Is the nucleic acid interval one meter or two meters?

For nucleic acid testing, it is a relatively safe distance to keep a distance of more than one meter. Relevant research shows that most droplets land on the ground within 0.8- 1.0 meters under the action of gravity. Therefore, it is suggested that when two people do nucleic acid at the same time, try to keep a distance of one meter before and after to reduce the risk of cross-infection.

However, because some viruses have strong viability, if they are in a windy environment, the scope of virus transmission may be relatively expanded, so the interval of one meter is not absolutely safe. It is recommended to wear a mask immediately after nucleic acid testing to avoid going to crowded places.

Every time nucleic acid is a large-scale nucleic acid, people need to line up to do nucleic acid. I believe that there will be such a problem in nucleic acid production sites everywhere, that is, people are too crowded. It is the most dangerous way to squeeze people at the moment of an epidemic, because it is uncertain whether there are positive cases in the team. Therefore, the safest way to do nucleic acid on a large scale is to line up in order to do nucleic acid, and everyone consciously separates one meter. The community can also use the building number as nucleic acid and avoid people waiting for a long time.
