"The new coronavirus spreads through the air"? U.S. agencies withdraw relevant epidemic prevention guidelines

　　China News Service, September 22. According to the American Chinese website, on the 21st, the Centers for Disease Control and Prevention (CDC) withdrew an epidemic prevention guide saying that the new crown virus may be spread through the air, saying that the guide was "misissued."

　　It is reported that the US Centers for Disease Control and Prevention issued this guidance on the 18th, stating that the new coronavirus can usually be "spread through respiratory droplets or fine particles (such as small aerosol particles)", even when people breathe.

　　However, the agency also claimed on the 21st that this guideline was "wrongly issued" and has now been deleted from the CDC website.

"The Centers for Disease Control and Prevention is currently updating its recommendations on the spread of the new coronavirus in the air," the agency said, and will release the updated statement later.

　　Currently, the CDC's guidelines on the coronavirus are the same as the guidelines before the update.

The guide states: "The virus spreads mainly from person to person." It mentions that the virus "may be spread in other ways," but it does not mention airborne transmission.

　　The CDC’s page states that the new coronavirus is mainly spread between people in close contact, and “spread through respiratory droplets produced when an infected person coughs, sneezes, or speaks.

　　In addition, the CDC has added new measures to its information about protecting yourself and others.

Previously, the agency recommended that people maintain a social distance of about 6 feet, wash their hands, clean and disinfect surfaces regularly, and cover their mouth and nose with a mask when they are around other people.

The new guidelines also recommend that people should stay at home and self-isolate when they are sick, and "use air purifiers to reduce airborne bacteria in indoor spaces."

It pointed out that masks should not replace other preventive measures.

　　The update also changed the statement surrounding asymptomatic transmission, from "some people without symptoms may be able to transmit the virus" to "people who are infected but show no symptoms can transmit the virus to other people."
