Keeping distance is cited as one of the most important COVID-19 prevention measures. In the recommendations of various organizations it is said that on the street, in a store or in transport, you should try to stay at a distance of one to two meters from other people. is that enough?

What they recommend to us

On April 1, the head of Rospotrebnadzor said that residents of Russia must maintain a distance of at least a meter between themselves. The department made an exception only for taxi passengers. A similar distance, but without reservations in favor of a taxi, is recommended by the World Health Organization. The US Centers for Disease Control and Prevention (CDC) believes that the distance should be two meters. The distance of 1.8 meters (six feet) is also often heard in the recommendations of doctors, hospitals and Internet resources.

Why distance is needed

The new coronavirus can be transmitted through the air, with droplets that form when coughing and sneezing. It is known that viruses can survive in the air for up to three hours. It is assumed that distance can protect against this route of infection. One study found that healthcare workers are less likely to get the flu when they are 1.8 meters away.

According to experts

In a comment to Live Science, Krys Johnson, an epidemiologist at Temple University, said the distance (1.8 meters) is more of a guideline than a clear prescription.

“Keeping a distance between yourself and other people with whom you do not live in the same apartment is very good. For premises, this should be considered the absolute minimum,”she said.

Johnson said that 1.8 meters is the average distance that droplets fly when coughing or sneezing. She noted that this measure is more likely to be effective, provided that people cover their mouths when they sneeze and are not very sick.

Those who consider such a distance to be sufficient have enough opponents.

“Probably 1.8 meters is not enough. This rule is based on research from the 1930s and 1940s. Since then, it has already been shown that it is wrong: the drops can fly further. Nonetheless, hospitals continue to believe this rule. It's like a flat earth theory - there is a chorus of believers shouting at anyone who argues with real evidence,”Professor Raina MacIntyre told Live Science.

Recently, a study appeared that showed that when sneezing, droplets fly much farther than previously thought. In addition, there is reason to believe that the new coronavirus can travel through the air in an aerosol.
