U.S. Centers for Disease Control and Prevention (CDC) on Monday stated that COVID-19 could spread through virus lingering in the air and sometimes even for hours. It further emphasised about the issues largely warned by public health experts about airborne transmission of the virus.
The CDC’s new rule was provided weeks after the agency published – and then removed – a similar warning, drawing flak over spreading of virus.
In Monday’s new guidance, CDC asserted that it traced contacts of people with COVID-19 who transmitting the infection to others who were more than 6 feet away. It was known to have propagated largely within closed spaces with poor ventilation. In view of this, CDC said researchers claim the amount of infectious smaller droplet and particles, or aerosols, produced by the covid effected people had become potential enough to spread the virus.
It is learnt that the revised guidance has come consequently after a team of U.S. scientists warned in an open letter published in medical journal Science on Monday, claiming that aerosols lingering in the air could be a major source of COVID-19 transmission.
CDC laid it’s point of emphasis earlier that close-contact transmission is more common than through air but switched to the other opinion and turned volte-faced after the latest development.
“The reality is airborne transmission is the main way that transmission happens at close range with prolonged contact,” the researchers said in a press meet.
