New CDC Coronavirus Guidelines Say Covid-19 Virus is Airborne

NEW YORK, KOMPAS.com - New CDC coronavirus guidelines say that the Covid-19 virus is airborne and can spread more than six feet through the air.

The top US public health agency’s new guideline was particularly emphasized for an airborne spread in poorly ventilated and enclosed spaces.

CDC officials maintained that such spread is uncommon and social distancing guidelines still make sense. However, several experts faulted the updated CDC guidelines.

They said the virus can spread more easily than the US health agency seems to be indicating and suggested that the public should wear masks even in prolonged outdoor gatherings when they are more than six feet apart.

The virus "is traveling through the air and there is no bright line. You're not safe beyond 6 feet. You can't take your mask off at 6 feet," said Dr. Donald Milton of the University of Maryland School of Public Health.

For months, the health agency has said that the virus spreads mainly through small airborne droplets when an infected person coughs or sneezes.

Most CDC coronavirus guidelines about social distancing is built around that idea, saying that six feet is a safe buffer between people who are not wearing masks.

In interviews, CDC officials have also acknowledged growing evidence that the virus can sometimes spread on even smaller particles called aerosols that spread over a wider area.

In the update posted on its website, the agency again acknowledged recent research showing people with Covid-19 infected others who were more than six feet away or shortly after an infected person left an area.

CDC officials called those ”limited, uncommon circumstances”.

In those cases, spread occurred in poorly ventilated and enclosed spaces where people were doing activities that caused heavier breathing, like singing or exercise, CDC officials said.

People can protect themselves by staying at least 6 feet away from others, wearing a mask, washing their hands, cleaning touched surfaces and staying home when sick.

Last month, the top US health agency ignited controversy among experts when it quietly posted an update that seemed to suggest the agency's position had changed, and then within days took it down again.
