There is a "real risk" that coronavirus will spread through the air, which means it can be transmitted from one individual to another due to microscopic particles standing in the air, according to a public letter signed by 239 scientists and published. at Oxford University Press. They call on the World Health Organization and other public health organizations to change their guidelines for coronavirus.
"Hand washing and social distance are appropriate, but in our opinion, insufficient to provide protection against the spread of the virus in the air," the letter reads.
The WHO says the virus is spread through respiratory sprays that do not spread far, so a distance of 1.5-2 meters is advised.
"Spraying very large spots when you sneeze, for example, they come out of your mouth and fall straight to the ground due to gravity," Dr. Ron Elfenbein explained to CBSN. "While airborne transmission means the virus can stay in the air for a long time. ?
The authors of the letter cited a study conducted at a Chinese restaurant, where there was no evidence of direct or indirect contact between the people present, but the virus was transmitted.
This factor is completely dangerous indoors. Scientists recommend opening doors and windows, constant checks for infection and air filtration.
