Centers for Disease Control and Prevention came out with numbers on the airborne spread of the virus that are being challenged….
The longer scientists study the Covid-19 virus the better they get at actually knowing about it and how it works….
There is no doubt that the vaccinations and mask wearing work….
When the Centers for Disease Control and Prevention released new guidelines last month for mask wearing, it announced that “less than 10 percent” of Covid-19 transmission was occurring outdoors. Media organizations repeated the statistic, and it quickly became a standard description of the frequency of outdoor transmission.
But the number is almost certainly misleading.
It appears to be based partly on a misclassification of some Covid transmission that actually took place in enclosed spaces (as I explain below). An even bigger issue is the extreme caution of C.D.C. officials, who picked a benchmark — 10 percent — so high that nobody could reasonably dispute it.
That benchmark “seems to be a huge exaggeration,” as Dr. Muge Cevik, a virologist at the University of St. Andrews, said. In truth, the share of transmission that has occurred outdoors seems to be below 1 percent and may be below 0.1 percent, multiple epidemiologists told me. The rare outdoor transmission that has happened almost all seems to have involved crowded places or close conversation….
This isn’t just a gotcha math issue. It is an example of how the C.D.C. is struggling to communicate effectively, and leaving many people confused about what’s truly risky. C.D.C. officials have placed such a high priority on caution that many Americans are bewildered by the agency’s long list of recommendations. Zeynep Tufekci of the University of North Carolina, writing in The Atlantic, called those recommendations “simultaneously too timid and too complicated.”
They continue to treat outdoor transmission as a major risk. The C.D.C. says that unvaccinated people should wear masks in most outdoor settings and vaccinated people should wear them at “large public venues”; summer camps should require children to wear masks virtually “at all times.”
These recommendations would be more grounded in science if anywhere close to 10 percent of Covid transmission were occurring outdoors. But it is not. There is not a single documented Covid infection anywhere in the world from casual outdoor interactions, such as walking past someone on a street or eating at a nearby table….
Dr. Fauci on mask wearing….
“We’ve had practically a nonexistent flu season this year merely because people were doing the kinds of public health things that were directed predominantly against covid-19,” Fauci said.
Fauci added that it is “conceivable” that during seasonal periods where respiratory-borne viruses such as the flu are prevalent, people might decide in the next year or two to wear masks to diminish the possibility of either spreading or catching these diseases.
Common viruses such as influenza have virtually disappeared this year, partly because of coronavirus restrictions like face masks. And a sharp decline in flu infections during this year’s season has led to only one registered pediatric death, compared with dozens in past years, official data shows….
