The CDC pulled its guidelines on how Covid spreads by aerosols shortly after posting them online.
CDC Reverses Guidelines
In a move sure to cause confusion the CDC Removes Guidelines Saying Coronavirus Can Spread From Tiny Air Particles.
For months, the CDC said the new coronavirus is primarily transmitted between people in close contact through large droplets that land in the mouths or noses of people nearby. On Friday, however, it added that tiny particles known as aerosols could transmit the virus. Then abruptly on Monday, the CDC reversed course and removed the additions. Much of the guidelines’ earlier description of Covid-19 transmission, emphasizing spread via large droplets, was restored.
The agency last week walked back a controversial recommendation that close contacts of Covid-19 patients don’t need to get tested if they don’t have symptoms.
