A prestigious panel of scientific experts told White House officials during a briefing on Wednesday evening that the spread of the coronavirus can occur not only through coughing and sneezing, but also through speaking and even just breathing. according to CNN .
"While the current specific research is limited, the results of the available studies are consistent with the possibility that the virus also contaminates through the aerosol produced by normal breathing", reads a letter of Harvey Fineberg, chairman of the National Standing of Sciences Standing Committee.
The letter was in response to a question raised by Kelvin Droegemeier, the director of the Office of Science and Technology Policy at the White House.
"The research currently available supports the possibility that the coronavirus can be spread via bioaerosol generated directly from the exhalation of patients," the letter continues.
Fineberg told the CNN that this danger is not as high in open and ventilated areas.
“If you generate an aerosol containing the virus in a room with no air circulation, it is conceivable that if you later walk through it, you can inhale the virus ", he said Fineberg to the CNN . "But if you're out in the open, the breeze will probably disperse it."
The letter comes in response to a specific question sent by the surgeon general Jerome Adams. The latter asked officials from the US Centers for Disease Control to reconsider the initial decision to advise the public against wearing masks. A decision that was initially also made here in Italy, and which persists in spite of the increasing evidence.
“We have learned that there is a good deal of asymptomatic spread of the coronavirus. This is why we asked the CDC to verify whether the fact that more people wear masks or not prevents the transmission of the disease to other people ”. This the declaration di Adams Wednesday on “Good Morning America. "
The clarification in response was quite eloquent. The rules on masks will likely change very soon.
