The Centers for Disease Control and Prevention (CDC) updated its coronavirus guideline on Monday. The updated version states that Covid-19 is spread not only by droplets but also by air, which means that a distance of two meters is not enough to protect oneself from the virus indoors. Especially in places where people sing or talk often. That is why wearing masks is vital.

Until now, there has been no mention in the CDC manual that even the smallest particles emitted by an infected person could move in space and be released into the air (unlike droplets that soon fall on any surface). “Covid-19 can be spread through the air. Some infections can be spread through droplets and small particles in the air and can even stay in the air for several hours. The virus can infect a healthy person even when it is quite far away from an infected person. “He stands and even after the infected person leaves the room.”

Last month, the CDC made a small change to the guidelines for the airborne transfer of Covid-19, but the amendment was later dropped because officials said the opinion had not yet been scientifically tested.

The same virus, depending on the circumstances, can move through the air and may not. For example, in an enclosed space, air conditioning can spread the virus from an infected person in all directions, infecting healthy people even more than 2 meters away. The same case was reported in South Korea, at Starbucks, where 27 people were infected simultaneously.

Some viruses, such as measles, are known to be transmitted by airborne droplets and are therefore easily transmitted. Other viruses (even the flu) are spread by droplets. COVID-19-like viruses are among these two types of viruses and are spread in both droplets and gas. Therefore, for our own safety, we must follow the advice of doctors: avoid crowded places and wear masks constantly.

“Airborne viruses are less dangerous in the open because they are rapidly dispersed by large streams of air, and frequent ventilation of enclosed spaces significantly reduces the risk of spreading the disease,” said Zeinef Tufek, a reporter for The Atlantic magazine. Frequent hand washing and social distance are still needed. The new document again states that the chances of transmitting the coronavirus through the surface are not great.

Winter is approaching, it is already cold outside and we all want to spend time in cozy and warm spaces, however, in today’s conditions, the best place to meet loved ones is again open spaces where the risk of spreading the virus will below.
