First topic message reminder :

As evidence the WHO did not even recommend masks except for the sick. There is not one peer reviewed document showing it is. And the outbreak would be much more severe.

Shrestha et al. examined SARS-CoV-2 viral load over time among 230 health care personnel with COVID-19 who did not require hospitalization. Viral loads in the upper respiratory specimens (n=528) peaked by 2 or 3 days from symptom onset and decreased rapidly thereafter, with >85% of the area under the curve occurring in the first five days.

I do not believe it is airborn it is touch - Page 3 Empty shown 45% of air samples but we do not have that many sick

Post by dean Thu Jul 09, 2020 6:34 pm

wow ....   if they would only figure out what their research was actually telling them.

we can assume that any place a infected person is they are breathing and as noted by this study in a london hospital RNA was found in 38.7 percent of air samples and 52.3 percent of surfaces.       So this should be true anyplace.      And hense 45% of the air should make people sick because they are breathing it in so anyone walking in the vacinity would be ill.   Yet we know that is not true by the fact of the restaurant and bus ones and how the bar one very few people did get sick, should have been nearly all who were there.   But if touch the probability of you touching the same place and then your face is much lower.

Zhou et al. collected air and surface samples from seven clinical areas occupied by COVID-19 patients, as well as one public area of a London hospital. Overall, viral RNA was detected on 52% (114/218) of surfaces and 39% (14/31) of air samples, but no virus was cultured. Viral RNA was more likely to be found in areas immediately occupied by COVID-19 patients than in other areas (64% vs. 45%). These findings suggest there is a high risk of environmental contamination with viral RNA within health care settings, though the implications for infectious virus are less clear.

got to love this one, if it was airborne at a bar it would not be 0.6% of the people getting infected.

https://globalhealth.washington.edu/covid-19-literature-situation-report#.XwV0Dbc49so.facebook


As of May 25, 246 COVID-19 cases have been linked to an outbreak at a nightclub in Seoul, South Korea. Nightclubs in South Korea that had been closed previously as part of the social distancing policy re-opened on April 30, ahead of the April 30–May 5 Golden Week holiday. Through large scale contact tracing, Kang et al. tested 41,612 nightclub visitors and their contacts, of whom 0.6% were positive: 96 (39%) of SARS-CoV-2 positive persons were primary cases and 150 (61%) were secondary contacts. This suggests that superspreading events related to nightclubs have the potential to spark a resurgence of cases in South Korea.

wtf is wrong with these scientists and believing a bar is not touch. Again from Black lives matters marches we do not have evidence being presented any spikes. But this bar in the usa has 100 infected. ya I know they are not looking at the arizona University study that showed with a surface coating that last 90 days a reduction of 35% of hospital acquired infections, and they one is not immediately effective on surfaces. But when a door handle was wiped before the next person they showed a drop from was it 50% of surfaces to less than 5% in a clinic.

We have not heard of a huge jump from the trump indoor gathering, that people were not wearing masks but i would guess washing hands.

this was 239 from around the world so not even one per country. decent wring of the article, as they did put in some of the contrarian experts, the ones that support my side of the case.

https://news.yahoo.com/239-experts-1-big-claim-151916602.html


239 Experts With 1 Big Claim: The Coronavirus Is Airborne


The coronavirus is finding new victims worldwide, in bars and restaurants, offices, markets and casinos, giving rise to frightening clusters of infection that increasingly confirm what many scientists have been saying for months: The virus lingers in the air indoors, infecting those nearby.

......

Dr. Benedetta Allegranzi, the WHO’s technical lead on infection control, said the evidence for the virus spreading by air was unconvincing.

“Especially in the last couple of months, we have been stating several times that we consider airborne transmission as possible but certainly not supported by solid or even clear evidence,” she said. “There is a strong debate on this.”.....

...

“There is no incontrovertible proof that SARS-CoV-2 travels or is transmitted significantly by aerosols, but there is absolutely no evidence that it’s not,” said Dr. Trish Greenhalgh, a primary care doctor at the University of Oxford in Britain.

https://www.scientificamerican.com/article/how-coronavirus-spreads-through-the-air-what-we-know-so-far1/




How Coronavirus Spreads through the Air: What We Know So Far
The virus that causes COVID-19 can persist in aerosol form, some studies suggest. But the potential for transmission depends on many factors, including infectiousness, dose and ventilation


A preprint (not yet published) study led by Santarpia and his colleagues similarly found evidence of viral contamination in air samples and surfaces from rooms where COVID-19 patients were being kept in isolation. “I think there are a lot of us—myself included—who feel very strongly that the airborne route of transmission is very possible,” he says. “I would hesitate to call it proven by any means. But I think there’s mounting evidence to support it.”

Both the Nature study and Santarpia’s paper measured viral RNA, not actual virus, so it is not clear that the material found in aerosols was functionally infectious. “Finding RNA doesn’t tell you [that] you have aerosol spread,” says Perlman, who was not involved in either study.


ADVERTISEMENT
Another paper, recently published in the New England Journal of Medicine, showed that infectious SARS-CoV-2 virus can remain in aerosols for at least three hours—and for several days on various surfaces—in a laboratory setting. But the amount of viable virus diminished significantly during that time. Scientists do not know the infectious dose of SARS-CoV-2. (For influenza, studies have shown that just three virus particles are enough to make someone sick.)

Overall, most of the evidence that SARS-CoV-2 can become airborne comes from clinical settings—which tend to have a lot of sick people and may host invasive procedures, such as intubations, that can cause patients to cough, generating aerosols. It is not clear how representative of everyday environments these areas are. “There is not much convincing evidence that aerosol spread is a major part of transmission” of COVID-19, Perlman says.



The likelihood of airborne transmission—especially compared with other routes, such as droplets or surfaces—remains unclear. Most researchers still think the new coronavirus is primarily spread via droplets and touching infected people or surfaces. So diligent hand washing and social distancing are still the most important measures people can take to avoid infection.

coating that acts in 2 hours was able to cut 2 hospital infection rates by 36%. and door handle wiping cut contamination by 4 ties.
https://azbigmedia.com/business/uarizona-study-surface-coatings-may-fight-virus-spread/

The standard practice of surface disinfection using liquid-based chemistries according to product label instructions can render many viruses – including the coronaviruses – noninfectious,” Ikner said. “In contrast, high-touch surfaces treated with continuously active disinfectants are hostile environments to infectious viruses upon contact and demonstrate increasing effectiveness over time.”

Continuously active disinfectant technology has been around for almost a decade but has been focused primarily on controlling hospital-acquired bacterial infections, such as invasive methicillin-resistant Staphylococcus aureus, or MRSA.

UArizona researchers from the Mel and Enid Zuckerman College of Public Health investigated the impact of antimicrobial surface coatings in reducing health care-associated infections in two urban hospitals. The results of that study were published in October and found a 36% reduction in hospital-acquired infections with the use of a continually active antimicrobial.

“As communities are reopening after weeks of stay-at-home restrictions, there is significant interest in minimizing surface contamination and the indirect spread of viruses,” Gerba said.

Previous research on the environmental spread of viruses through contaminated surfaces modeled the spread of germs and the risk of infection in an office workplace. In that study, a contaminated push-plate door at the entrance of an office building led to the contamination of 51% of commonly touched surfaces and 38% of office workers’ hands within just four hours. With the use of disinfecting wipes, environmental contamination was reduced to 5% of surfaces and 11% of workers’ hands.

Black Light Experiment Shows How Quickly COVID-19 Can Spread | NowThi  


 
This black light experiment shows how easily a virus like the coronavirus can spread in public.

https://www.businessinsider.com/video-japan-nhk-uv-light-how-virus-spread-restaurant-2020-5?r=MX&IR=T  


A video with UV light shows just how far a virus can spread between 10 people at a buffet  


 
A popular video in Japan released May 8 shows how quickly a virus can spread among restaurant diners.
The Japanese state broadcaster NHK gathered 10 volunteers to eat as normal in a simulated buffet environment.
One person was chosen to be carrying the virus, and fluorescent paint was put on the person's hand to represent it.
The 10 people were then left for 30 minutes to get food from the buffet, sit down together, and eat.
Ultraviolet light was then used to lay bare how the paint had spread. Scroll down to watch the video.
All nine other people, table surfaces, glassware, and serving utensils bore traces of the paint within minutes, NHK said.
Three people had traces of the paint on their faces.
Hiroyuki Kunishima, of the St. Marianna University School of Medicine, told NHK that a "high-touch surface" like tongs or container lids were "harboring danger."
Two health experts told CNN the lesson to learn was that regular handwashing is key to stopping a virus from spreading.

70% of people infected with the coronavirus did not pass it to anyone, preliminary research shows. Superspreading events account for most transmission.

Reuters


An average person with the coronavirus infects about two other people, but an infected person sometimes passes the virus to far more people during a super-spreader event.

New research suggests such events, which typically involve indoor gatherings, are responsible for most coronavirus transmission.

Experts found that just 20% of coronavirus cases result in 80% of transmission. An estimated 70% of infected patients studied didn't pass the virus at all.

By targeting locations and activities that beget super-spreading, countries may be able to avoid more lockdowns during future waves of infections.

Visit Business Insider's homepage for more stories.

Super-spreader events, in which one person infects a disproportionately large number of others, are the primary means by which the coronavirus spreads, new research suggests.

A group of epidemiologists in Hong Kong found that just 20% of cases studied there were responsible for 80% of all coronavirus transmission. The researchers also found that 70% of people infected with the coronavirus didn't pass it to anyone else, and that all super-spreading events involved indoor social gatherings.

"That's the picture we have so far," Ben Cowling, one of the study co-authors, told Business Insider. "Super-spreading events are happening more than we expected, more than what could be explained by chance. The frequency of super-spreading is beyond what we could have imagined."

Microbial transmission in an outpatient clinic and impact of an intervention with an ethanol-based disinfectant

Conclusions

Microbes spread quickly in an outpatient clinic, reaching maximum contamination levels 2 hours after inoculation, with the highest contamination on examination room door handles and nurses’ station chairs. This study emphasizes the importance of targeted disinfection of high-touch surfaces.

Survival of Influenza A(H1N1) on Materials Found in Households: Implications for Infection Control  


 
In conclusion, testing two H1N1 strains of influenza A (one of which was a 2009 pandemic virus) demonstrates that in an environment that is consistent with indoor domestic settings in temperate zones, virus deposited onto the touched environment is likely to survive up to a few hours, though rarely more than nine hours, on the vast majority of surfaces. Metallic and non-metallic non-porous materials pose the greatest risk and should be targeted for frequent cleaning if situated in close proximity to patients infected with influenza virus; fortunately the latter are also more conducive to surface cleaning with a wide variety of simple cleaning agents [12]. Whilst our data suggest that the risk of virus transmission might last several hours after deposition, we generated very little data suggesting that appreciable amounts of virus survived much beyond nine hours. This probably means that frequently touched environments such as classrooms, offices and living rooms, which are then left unoccupied overnight, will not contain much viable virus on surfaces by the next morning. Nevertheless, the data still support frequent cleaning of commonly touched items and surfaces throughout the working day, particularly when symptomatic persons are present, for example in physician waiting rooms. In terms of cleaning regimens, one critically important consideration is that survival of virus in high titres for prolonged periods is not necessary for fomite transmission if surfaces are frequently re-inoculated (e.g. by toddlers). However the contribution of such indirect transmission relative to respiratory droplets directly from one person to another or relative to aerosol transmission remains unknown.

Beware of Workplace Germs


You collect more than a paycheck at work: Every time you touch your desk, keyboard, or telephone, you pick up germs. More than 10 million bacteria are on a typical office desk -- 400 times more bacteria than found on the average toilet seat -- which means that typing an email or making a call puts you at risk for illnesses.

The reason is pretty simple. "We touch a lot of different surfaces that hundreds of others might be touching," says Kelly Reynolds PhD, a professor and environmental microbiologist at the University of Arizona. "Germs spread quickly."

Even when professional cleaners do their best, germs linger. Bacteria counts are lowest at the beginning of the workday (because offices are often cleaned overnight), but it doesn't take long for germs to show up for work, too.

"As the day ramps up and more people touch more surfaces, the risk of coming in contact with bacteria goes up. Contamination levels reach their peak around lunch," Reynolds says.

CONTINUE READING BELOW
In one study, researchers asked volunteers to be artificially inoculated with a benign virus to test how fast it would spread. They found that "infected" co-workers spread the virus to 50% of workplace surfaces within 4 hours of arriving at work; thanks to shared contact with those surfaces, half of their co-workers also tested positive for the viruses.

To keep germs in check and avoid illness, clean your workspace. Wipe down your desktop, monitor, keyboard, computer mouse, and phone at least once a day -- but skip soap and water and opt for something stronger.

The CDC’s lesser emphasis on infected surfaces as part of the spread of COVID-19 is slightly different from that of the World Health Organization (WHO). The WHO states online that “COVID-19 spreads primarily from person to person,” but adds that, “it can also spread if you touch contaminated objects and surfaces.” The WHO even breaks down for readers all of the commonly-touched surfaces to be wary of, like doorknobs, computers, elevator buttons, and pens, noting that “If you touch something contaminated and then touch your face… you might fall ill.”

I do not believe it is airborn it is touch - Page 3 Empty what is the infectious dose

Post by dean Mon May 18, 2020 9:26 pm

https://www.nature.com/articles/d41586-020-00974-w

Is the coronavirus airborne? Experts can’t agree
The World Health Organization says the evidence is not compelling
, but scientists warn that gathering sufficient data could take years and cost lives.



In a scientific brief posted to its website on 27 March, the World Health Organization said that there is not sufficient evidence to suggest that SARS-CoV-2 is airborne, except in a handful of medical contexts, such as when intubating an infected patient.

Whether people with COVID-19 produce enough virus-laden aerosols to constitute a risk is also unknown, says Lloyd-Smith. Air sampling from people when they talk, breathe, cough and sneeze — and testing for viable virus in those samples — “would be another big part of the puzzle”, he says. One such study failed to detect viral RNA in air collected 10 centimetres in front of one person with COVID-19 who was breathing, speaking and coughing, but the authors didn’t rule out airborne transmission entirely6.

Another crucial unknown is the infectious dose: the number of SARS-CoV-2 particles necessary to cause an infection, says Lloyd-Smith. “If you’re breathing aerosolized virus, we don’t know what the infectious dose is that gives a significant chance of being infected,” he says. An experiment to get at that number — deliberately exposing people and measuring the infection rate at different doses — would be unethical given the disease’s severity.

here is another example a hospital reduced infections by 36% by using a coating for weeks that killed viruses and bacteria.

https://uanews.arizona.edu/story/continuously-active-surface-disinfectants-may-provide-additional-barrier-against-spread


Continuously Active Surface Disinfectants May Provide Additional Barrier Against the Spread of Viruses
As the novel coronavirus pandemic continues, UArizona researchers are evaluating the potential of antiviral surface coatings in continued defense against the environmental spread of viruses.


In the battle to slow or prevent the transmission of viruses, such as the novel coronavirus, continuously active disinfectants could provide a new line of defense, according to a recent University of Arizona study released on the health sciences preprint server MedRxiv.

While disinfecting high-contact surfaces is an important practice to prevent the spread of pathogens, these surfaces can be easily re-contaminated after the use of conventional surface disinfectants. Alternatively, continuously active disinfectants work to actively kill microorganisms and provide continued protection over an extended period of time.

"During the course of respiratory illnesses such as COVID-19, aerosols released during sneezing and coughing contain infectious viruses that will eventually settle onto various surfaces," said Luisa Ikner, associate research professor in the Department of Environmental Science and lead author of the study. "Factors including temperature, humidity and surface type can affect how long viruses such as SARS-CoV-2 will remain infectious after surface deposition."

"The only tools we have currently in reducing the environmental spread of viruses via surfaces are hand sanitizer, hand washing and the disinfection of surfaces," said Charles Gerba, a microbiologist and professor of environmental science in the College of Agriculture and Life Sciences. "This technology creates a new barrier in controlling the spread of viruses in indoor environments."

Gerba and his research team designed and conducted the study – which was funded by Allied BioScience, a company that manufactures antimicrobial surface coatings – to evaluate continuously active antimicrobial technology and its potential use against the transmission of viruses.

"We evaluated this technology by testing a modified antimicrobial coating against the human coronavirus 229E, which is one of the viruses that causes the common cold," Gerba said. "Even two weeks after the coating was applied, it was capable of killing more than 99.9% of the coronaviruses within two hours."

Human coronavirus 229E is similar in structure and genetics to SARS-CoV-2 but causes only mild respiratory symptoms. It can therefore be safely used as a model for SARS-CoV-2 to evaluate antiviral chemistries. The results from these experiments may provide new opportunities for controlling the environmental transmission of COVID-19.

"The standard practice of surface disinfection using liquid-based chemistries according to product label instructions can render many viruses – including the coronaviruses – noninfectious," Ikner said. "In contrast, high-touch surfaces treated with continuously active disinfectants are hostile environments to infectious viruses upon contact and demonstrate increasing effectiveness over time."

Continuously active disinfectant technology has been around for almost a decade but has been focused primarily on controlling hospital-acquired bacterial infections, such as invasive methicillin-resistant Staphylococcus aureus, or MRSA.

UArizona researchers from the Mel and Enid Zuckerman College of Public Health investigated the impact of antimicrobial surface coatings in reducing health care-associated infections in two urban hospitals. The results of that study were published in October and found a 36% reduction in hospital-acquired infections with the use of a continually active antimicrobial.

"As communities are reopening after weeks of stay-at-home restrictions, there is significant interest in minimizing surface contamination and the indirect spread of viruses," Gerba said.

Previous research on the environmental spread of viruses through contaminated surfaces modeled the spread of germs and the risk of infection in an office workplace. In that study, a contaminated push-plate door at the entrance of an office building led to the contamination of 51% of commonly touched surfaces and 38% of office workers' hands within just four hours. With the use of disinfecting wipes, environmental contamination was reduced to 5% of surfaces and 11% of workers' hands.

"Antimicrobial coatings could provide an additional means of protection, reducing the spread of coronaviruses in indoor environments and public places where there is continuous contamination," Gerba said. "We're evaluating a number of products right now and believe it may be the next major breakthrough in environmental infection control."

https://www.iamat.org/country/ecuador/risk/tuberculosis







Tuberculosis (TB) is an airbone bacterial infection caused by Mycobacterium tuberculosis. TB can be acquired by breathing contaminated air droplets coughed or sneezed by a person nearby who has active Tuberculosis. Humans can also get ill with TB by ingesting unpasteurized milk products contaminated with Mycobacterium bovis, also known as Bovine Tuberculosis. The most common form of the infection is pulmonary TB which affects the lungs. In some cases, the bacteria can also attack the lymphatic system, central nervous system, urogenital area, joints, and bones.

Risk
Mycobacterium tuberculosis is present worldwide and typically spreads in cramped, overcrowded conditions. There is no evidence that pulmonary TB is more easily transmitted in airplanes or other forms of public transportation. Long-term travellers, those with a weakened immune system or visiting friends and relatives (VFR travellers) in areas where Tuberculosis is endemic are at risk. Humanitarian and healthcare personnel working in communities with active TB are also at increased risk. Persons with active TB should not travel.

Ok here is a great example, 300-400 people drove 2 hours for a Texas high school state play off basketball game game where there is lots of yelling .   and only 3 people from that town/county to date got sick in 2 months.     If airborne it would have nailed so many at that incident location.    

https://news.yahoo.com/became-real-became-alive-coronavirus-105817855.html  



The basketball game
B’Anna Scroggins, her husband, Billy, and their friends packed into the Texan Dome at South Plains College on Friday, March 6, wearing their black and gold Vega Longhorns T-shirts. The regional basketball tournament had drawn a large crowd to watch the high school boys teams battle it out for a chance to go to the state finals.

The tournament was almost two hours away, but that’s what Vega residents do – support their students, even when their own kids have graduated or don’t play sports.

“The whole town was there,” said Shaye Pingel Warner, one of B’Anna’s best friends. “I bet there were 300-400 people there from our side. Probably more.”  



The threat of the disease spreading into Oldham County remains ever present. While the number of confirmed COVID-19 cases is still three, the rural county is surrounded by areas with far more cases.

Potter County, home of Amarillo and directly east of Oldham County, has about 1,000 cases of the virus. Nearby Moore County has more than 400 and Randall County has about 300.

Many Oldham residents commute to work in Amarillo or other cities, which means more cases could show up.

How coronavirus spread through a birthday and a funeral in Chicago
NEWS

by: Nexstar Media Wire

CHICAGO, ILLINOIS – MARCH 26: A Chicago Cubs fan wearing protective gear walks past a statue of the late long-time sportscaster Harry Caray outside of Wrigley Field on what was to be opening day for Major League Baseball on March 26, 2020 in Chicago, Illinois.

CHICAGO (NEXSTAR) – One person who attended a birthday and a funeral in Chicago earlier this year likely left 16 people infected with coronavirus, three of whom died, according to a Centers for Disease Control and Prevention study.

The gatherings happened about three days apart, before social distancing policies were implemented. The cases (seven confirmed and nine probable) range in age from 5 to 86 years old.

The first patient, labeled A1.1, had recently traveled out of state and had some mild respiratory symptoms, but decided to attend the funeral of a friend anyway. He hadn’t been tested at the time and didn’t know he had COVID-19, which investigators later confirmed.

The evening before the funeral, he spent about three hours with family members of the deceased friend, eating a “potluck-style” meal from common serving dishes. When he said his goodbyes, he expressed his condolences and hugged the other people at the dinner, according to the CDC.


(CDC)
Two of the family members started to experience COVID-19 symptoms between two and four days later, one of whom later died. A third developed suspected COVID-19 symptoms six days after the funeral.

The next day at the funeral, A1.1 had close contact with a fourth person, who later visited the sick family member in the hospital. That person embraced the family member without any protective gear and later developed a fever and cough believed to be from the novel coronavirus.

Three days after the funeral, still experiencing symptoms, patient A1.1 went to a birthday party attended by nine other family members. A1.1 embraced everyone at the party and shared food during a three-hour span.

Seven people at the party got sick, two of whom later died despite being placed on ventilators. A home care nurse and another family member developed COVID-19 after taking care of one of the patients without using protective gear. The family member is then believed to have passed it to a home contact who didn’t go to the party.

Several days after the birthday, three of the family members went to church while experiencing symptoms; at least one person at the service who touched the same offering plate and sat one row away developed confirmed COVID-19.

The study shows how quickly COVID-19 can spread through a community, and, the CDC points out, doesn’t include any potential cases of asymptomatic infection.

“Overall, these findings highlight the importance of adhering to current social distancing recommendations, including guidance to avoid any gatherings with persons from multiple households and follow state or local stay-at-home orders,” the CDC says in the report.

https://www.who.int/docs/default-source/coronaviruse/who-china-joint-mission-on-covid-19-final-report.pdf

Report of the WHO-China Joint Mission
on Coronavirus Disease 2019 (COVID-19)


Routes of transmission

COVID-19 is transmitted via droplets and fomites during close unprotected contact between
an infector and infectee. Airborne spread has not been reported for COVID-19 and it is not
believed to be a major driver of transmission based on available evidence; however, it can
be envisaged if certain aerosol-generating procedures are conducted in health care facilities.
Fecal shedding has been demonstrated from some patients, and viable virus has been
identified in a limited number of case reports. However, the fecal-oral route does not
appear to be a driver of COVID-19 transmission; its role and significance for COVID-19
remains to be determined. Viral shedding is discussed in the Technical Findings (Annex C)
My add in China they found a patient had taken a long bus ride maybe 8 hours, the trackers got the bus film and located all the people on the bus and found very few of them were sick, the infected person was in the back of the bus and one person in the middle of the bus isle seat fot sick and only the people close to him tested positive.   So it is not as easily transmitted by air as one would envision.      Also if it was that easy entire planeloads would always be succumbing to flus yet I rarely get sick when flying and no one would fly if it was found it was that easy to be infected.  From this article, it also notes that 78-85% is family spread.

Household transmission
In China, human-to-human transmission of the COVID-19 virus is largely occurring in
families. The Joint Mission received detailed information from the investigation of clusters
and some household transmission studies, which are ongoing in a number of Provinces.
Among 344 clusters involving 1308 cases (out of a total 1836 cases reported) in Guangdong
Province and Sichuan Province, most clusters (78%-85%) have occurred in families.
Household transmission studies are currently underway, but preliminary studies ongoing in
Guangdong estimates the secondary attack rate in households ranges from 3-10%.

and lastly, when studying the H1N1 it was found that there was a 30% drop in spreading when schools were closed.    So I conclude the following, a person in a house gets it, they may be asymptomatic, the entire family gets it, the person with a job goes to work and co-workers who are in close proximity toch something that person touches, like he hands them a pen, they water cooler button, , coffee pot handle, elevator button.      That person goes home and gets their family sick by door know to home, the child gets infected and is asymptomatic and goes to school and during gym gets hit in the face with a ball and throws it and another catches it and that child thows it and so on so all the kids get it.    They take it home and again the entire family gets it.    mom or dad go to work and it goes and goes.

bus example
https://www.scmp.com/news/china/science/article/3074351/coronavirus-can-travel-twice-far-official-safe-distance-and-stay

These findings, from a group of official researchers from Hunan province investigating a cluster case, challenge the advice from health authorities around the world that people should remain apart at a “safe distance” of one to two metres (three to six and a half feet).
Their work was based on a local outbreak case on January 22 during the peak Lunar New Year travel season. A passenger, known as “A”, boarded a fully booked long-distance coach and settled down on the second row from the back.
The passenger already felt sick at that point but it was before China had declared the coronavirus outbreak a national crisis, so “A” did not wear a mask, nor did most of the other passengers or the driver on the 48-seat bus.
Several passengers became infected during the four-hour bus journey.
Several passengers became infected during the four-hour bus journey.
China requires closed circuit television cameras to be installed on all long-distance buses, which provided valuable footage for researchers to reconstruct the spread of the virus on the bus, whose windows were all closed.

What you should know about DIY masks and ventilators

Regardless, Davies wrote in a recent summary of her team’s findings that social distancing, hand-washing, and the avoidance of face touching are by far the most effective ways to protect society, adding that masks should be a last resort that is meant to prevent “an unavoidable risk of exposure.” (Here’s how long coronavirus lasts on surfaces and in the air.)

cdc says wear masks..  I disagree for the reasons WHO still says.  

https://newatlas.com/health-wellbeing/cdc-guidance-cloth-face-masks-coronavirus-us-government/?utm_source=New+Atlas+Subscribers&utm_campaign=d2a9b4dfa3-EMAIL_CAMPAIGN_2020_04_06_08_13&utm_medium=email&utm_term=0_65b67362bd-d2a9b4dfa3-90245106

Experts have been divided on the topic of mask wearing over the past week. Some have suggested mass population mask wearing may reduce levels of community transmission considering there is increasing evidence of asymptomatic transmission. However, other experts have expressed concern masks can breed a false sense of security, resulting in wearers relaxing social distancing measures and general hygiene practices.

It is this particular concern that seems to be causing the World Health Organization to hold back from instituting general mask wearing recommendations. Michael Ryan, Chief Executive Director of the WHO Health Emergencies Programme, reiterated this point at the WHO’s most recent press briefing.


“We must preserve medical, surgical and respirator masks for our front-line workers but the idea of using respiratory coverings or mouth coverings to prevent coughing and sneezing projecting disease into the environment or towards others; that's a mechanical process and that in itself is not a bad idea but that doesn't negate the need for hand-washing, it doesn't negate the need for physical distancing, it doesn't negate the need for people to stay at home if there's a stay-at-home order in place,” said Ryan.

the argument of facemasks.     ,, they missed a few things in this research, one being it increased a person to believe they are secure so they spend more time out.   And stores are not happy with people hanging out, a letter from costco home depot employees say shop fast get out.   The employees are at larger risk the longer you think you are now safe so you stay longer.    Next this happened with me, they do note the education issue but missed a huge point,  people belive that the means of transmission is airborne when they have to use a mask, when the real culprit is touching what an infected person touched.      This was directly brought to my attention with a 14 year old child who told me I was wrong because they are telling everyone to wear masks.   This rationalization is from human factors people can visualize the cough with smell, someone releases gas and you can smell it through the entire room.   Hense a child and or not scientific person will only believe in facemasks and then clean their hands less.    In this case, she believed she could touch me and not wash her hands as much.    I find these researchers at Cambridge very lacking when they know that not one study ever done shows airborne is the transmission mechanism.  

https://newatlas.com/health-wellbeing/cambridge-coronavirus-widespread-cloth-face-mask-covid-19/

There are three general arguments frequently presented against broad general use of face masks: there is no evidence they protect a person from contracting the virus, mass adoption takes valuable resources away from frontline healthcare workers, and they instill a false sense of security in the wearer, resulting in reduced adherence to other important hygiene measures.


The editorial does note prior research investigating real-world mask use in regards to influenza transmission found masks confer “no significant protection.” However, many of the arguments for mask wearing suggest the point of advocating broad mask use is about limiting transmission from those unaware they are infected, instead of acting as a protective measure for healthy subjects.

Quotable: Dr. Michael Osterholm, at the University of Minnesota, said he had no doubt that the six-foot distance would clearly “reduce the number of droplets you come in contact with.” But, he added: “The question is what does it take for you to get infected? And that I think is the trillion-dollar question.”

I have said from the get go this is not airborn transmission .   I cited airplanes as not being overrun with all passengers getting sick and second the bus example (4 hour closed windows and not wearing masks and the people near the infected did not but some in the middle of the bus did.  and as noted WHO did not recommend masks.  And that there is one single article in all these years that viruses are airborn for transmission.  Ya you do not want a sick person coughing on ya.    the Chicago one where those the infected hugged at the wedding all got sick except one, and apparently no one else at the wedding did.   Still not one study showing airborne is able to show it.

This version updates the 27 March publication by providing definitions of droplets by particle size and adding three relevant publications.

Modes of transmission of the COVID-19 virus
Respiratory infections can be transmitted through droplets of different sizes: when the droplet particles are >5-10 μm in diameter they are referred to as respiratory droplets, and when then are <5μm in diameter, they are referred to as droplet nuclei.1 According to current evidence, COVID-19 virus is primarily transmitted between people through respiratory droplets and contact routes.2-7 In an analysis of 75,465 COVID-19 cases in China, airborne transmission was not reported.8

I believe this is a great example of how it is not airborne.     and how difficult it is to get it.       Here is a cruise ship  that had a case obviously they could not test and either could the hospital they dropped the Italian off at before getting to Florida to pick up more passengers, it holds 2200 to 2,800  passengers.         After departing florida 3 days later they drop of several sick passengers in PR still not knowing if it was corona virus for many more days to come .    Here is a guests video of the partying that took place the close eating and so on.   And you can even hear people coughing very heavily in the background in a closed area with many people in the area.      Also note these appear all to be 50 yo and older.    And when they were flown on a charter back to the USA  to atlanta the 600 americans and canadians we at the time checked for fever and if no fever were than allowed to go to other commercial  flights to their homes.         And again how many were asymptomatic and we did not see a huge death rate from that ship even with the higher age risk group and the flights people were not and still are not reporting sickness from those flight that took the people home.  

If it was as easy to catch from airborn everyone would have been sick getting off that boat and when they were flying instead of the dreaded 2 persons infected a day it would have been 20-200 infected on an airplane.    Would be astronomical numbers.       Watch this video.   amazingly reported only 15 have died  considering all were of the higherst risk age groups and the partying that went on in ultra close range, if airborne they would have all had it.

Cruise Ship Partied On as Coronavirus Spread    
Jennifer Catron boarded Carnival’s Costa Luminosa on March 5 for a transatlantic cruise. Her video diaries provide a window into life on board the ship as the coronavirus scare became a full-blown pandemic.

Coronavirus pandemic
See also: 2020 coronavirus pandemic on cruise ships § Costa Luminosa
On 2020.02.29, a 68-year-old Italian man in critical condition was transferred from Costa Luminosa to a hospital in the Cayman Islands due to heart issues.[16] On 2020.03.12, the Health Services Authority of the Cayman Islands announced that the man was their first confirmed coronavirus case.[17][18] His death was announced two days later.[16][19]

On 5 March 2020 the vessel left Fort Lauderdale for a transatlantic cruise. Two people disembarked with symptoms of the coronavirus in Puerto Rico. Subsequently, on 13 March 2020, it was confirmed to be due to coronavirus disease 2019 – the first known cases in Puerto Rico.[20] One of the two persons died several days later. Because of the virus outbreak several sick passengers were left at Tenerife and passengers were placed under quarantine in their rooms. The ship was not allowed to dock in Spain. It docked at Marseille, France, discharging sick passengers who flew home distributing the virus,[19] and went to Savona where the rest of the passengers were disembarked on 23 March, many of them sick.[21] After the disembarkation at Marseille, French authorities confirmed 36 people with COVID-19 infection.[22] On 21 March local news in Puerto Rico reported the death of the quarantined Italian woman.[23] On 7 April 2020, A Miami lawyer filed a lawsuit against the Costa Cruises over mishandling and allowing passengers to sail Costa Luminosa despite having flu-like symptoms.[24]


here is another note about Carnival cruise.   Seems the owner is a friend of trumps and is on the task force to re-open the country.    Shows how the company has cut corners many times with huge fines.    Yep thats they type of business leader we need helping the world.

As evidence the WHO did not even recommend masks except for the sick. There is not one peer reviewed document showing it is. And the outbreak would be much more severe.
