![]() The new guidance is also clear about asymptomatic transmission: “People who are infected but do not show symptoms can also spread the virus to others,” it says. In enclosed spaces with poor ventilation, a person who was breathing heavily – while singing or exercising, for example – can infect people who aren’t nearby, even after the person with Covid-19 has left the space. “Small droplets can also form particles when they dry very quickly in the airstream.”īut the CDC now says the virus can spread through small particles of virus that linger in the air and may be able to infect people more than 6 feet away. These droplets can range in size from larger droplets (some of which are visible) to smaller droplets,” the guidance says. ![]() “When people with COVID-19 cough, sneeze, sing, talk, or breathe they produce respiratory droplets. The agency still says Covid-19 is thought to mainly spread through close contact between people – within 6 feet of each other. Still, the available data suggest “it is much more common for the virus that causes COVID-19 to spread through close contact with a person who has COVID-19 than through airborne transmission,” the new guidance says. Such environments and activities may contribute to the buildup of virus-carrying particles.” In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. “Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19-positive person left an area. ![]() “CDC continues to believe, based on current science, that people are more likely to become infected the longer and closer they are to a person with COVID-19,” the agency said in a statement on Monday. The US Centers for Disease Control and Prevention has again updated its guidance about how Covid-19 spreads to include information about potential for airborne transmission. ![]()
