produced when a person coughs, sneezes or speaks, an assumption based on decades-old infection-control teachings about how respiratory viruses generally pass from one person to another.
Critics say that inaction at the agency led to national and local health agencies around the world being similarly sluggish in addressing the airborne threat. Having shifted its position incrementally over the past two years, the WHO also failed to adequately communicate its changing position, they say. As a result, it didn’t emphasize early enough and clearly enough the importance of ventilation and indoor masking, key measures that can prevent airborne spread of the virus.
Morawska presented what she says was a compelling case for airborne transmission. Two facts stood out. First, there was solid evidence that people were becoming infected even when they were more than one metre — the safe distance recommended by the WHO — from a contagious individual. Second, years of mechanistic studies had demonstrated how mucus in a person’s airway can spray into aerosols during speech and accumulate in stagnant rooms. Morawska felt rebuffed by the WHO and its advisers.
The disconnect was there even in the use of scientific terms. Infection-control experts have long drawn a hard line between droplet viruses and airborne ones, seeing only the latter as capable of travelling far and lingering in the air. “Dogmatic bias is certainly a big part of it,” says Don Milton, an occupational-health physician who studies aerosol transmission of infectious diseases at the University of Maryland in College Park.
According to Trish Greenhalgh, a primary-care health researcher at the University of Oxford, UK, the IPC GDG members were guided by their medical training and the dominant thinking in the medical field about how infectious respiratory diseases spread; this turned out to be flawed in the case of SARS-CoV-2 and could be inaccurate for other viruses as well. These biases led the group to discount relevant information — from laboratory-based aerosol studies and outbreak reports, for instance.
Still, Li is disappointed that it took the WHO until October 2020 to acknowledge that aerosols play a part in disease transmission in community settings. And in its updated guidelines on mask use, in December 2020, the agency still emphasized shortfalls and gaps in the evidence for aerosol transmission, and the need for more “high quality research” to understand the specifics of how the virus spreads.
Because they do not care…
I think many of us 'ordinary' folk suspected the possibility before they did 😒
Is there a shortened way to publish an article? Like in 300 words or 10 bullet points. I know writing an article is a great art and there are people who would learn from it. I’m just looking for a add on, to rush into the real “why” WHO did that and move on. Thanks!!
Because WHO is stupid and sold.
WHO are a waste of space and have been pretty much consistently wrong through the pandemic. The advice they gave in spring 2020 is likely one of the reasons that most countries failed to keep it out as WHO said it was not possible, and also recommended against masks
because they're corrupt
I've been saying it the whole time. This pandemic never had to be this bad. The world is controlled through politics alone. Any scientist not having their mouths controlled by money could tell you this.
Not only that. They should listen and take seriously all opinions; especially when they come from top scientists and Nobel laureates.

Health experts, FDA advisers struggle with COVID booster strategyWASHINGTON (TND) — Health officials say COVID case numbers have steadily risen over the last two weeks, driving fears of another surge. Several states have seen cases rise over the last few weeks. The biggest jump was in Washington, D. C. with a 106% increase. Doctors say the highly contagious BA. 2 variant is the likely culprit.

Why the WHO took two years to say COVID is airborneEarly in the pandemic, the World Health Organization stated that SARS-CoV-2 was not transmitted through the air. That mistake and the prolonged process of correcting it sowed confusion and raises questions about what will happen in the next pandemic.
