It is why the CDC’s guidelines tell you to quarantine for at least two weeks once you know you have been in close contact with a COVID-positive person. Even when you are infected, you might not test positive for days. And, for the zillionth time, lots of people - especially younger people like McEnany - might not show symptoms. They were meant to confirm cases in people who had symptoms. The tests were never intended or approved to give the “all-clear” to patients. The statement underscores how the White House misused rapid testing. It is a good time to remember that testing is not prevention.įollowing CDC guidelines, White House Press Secretary Kayleigh McEnany should have already been in a two-week quarantine when she briefed journalists (without wearing a mask) on Sunday. The list of White House occupants, staff and friends that have COVID-19 grew again Monday.
Testing does not protect you from COVID - how those rapid COVID tests are supposed to be used They say it is possible for COVID-19 to linger in the air for minutes, maybe even hours, if it is sucked into a heating or air conditioning system and blown back into a room. have said for some time that they thought airborne transmission, until now, has been unwisely ignored. The CDC is catching up with similar guidance from the World Health Organization, which published a brief in July that opened the door to the possibility of an airborne virus. The new guidance will also, no doubt, focus new attention on ventilation systems in businesses and schools. The new guidance makes it even more important to wear a mask - even when more than six feet away from others - because when you expel infected droplets in the air, the virus also lingers in the air. The people who were infected were in the same space during the same time or shortly after the person with COVID-19 had left. Under these circumstances, scientists believe that the amount of infectious smaller droplet and particles produced by the people with COVID-19 became concentrated enough to spread the virus to other people. Sometimes the infected person was breathing heavily, for example while singing or exercising. These transmissions occurred within enclosed spaces that had inadequate ventilation. There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. The new warning makes it clear that while most COVID-19 cases are spread by being within six feet of an infected person, it is also possible to be infected if you are far away from an infected person.
“This kind of spread is referred to as airborne transmission and is an important way that infections like tuberculosis, measles, and chicken pox are spread,” the CDC says. It is a significant statement since the warning focuses on how the virus may linger in the air and be spread in enclosed spaces with poor ventilation. But on Monday, the CDC reposted the new warning, only this time it was intentional.
