Nothing can happen in the air, can it? That depends, experts say:
One thing is clear: it is best for all of us to stay at home. Nevertheless, we also have to go shopping, visit the doctor or get some fresh air for a few minutes. But can we get infected? For example, in line at the bakery or when a jogger runs past us in the park?
The coronavirus is transmitted via droplets or smear infections. So you could get infected if you are close to someone who is infected with the virus and who may also be coughing you up. The droplets can fly up to two meters when coughing. The likelihood is particularly high if you are in a closed room or in an area where there is little air circulation with a sick person.
Do I get infected outside?
But can the virus spread while walking? According to the current study situation, it cannot be excluded because there are still too few studies. So far there is only one U.S. study of the NIH health institute. The researchers demonstrated that the virus stays in the air for up to three hours when sprayed with a spray. Christian Drosten, a virologist from the Charité in Berlin, says in the podcast of the NDR: “Someone coughs up the virus or has a wet pronunciation – then the virus stays in the air a short time in front of and around these people and then falls relatively quickly to the ground. ” He also emphasizes: “When you are outside, what you exhale is diluted and, of course, the virus is also diluted.”
But it is also not very likely. Because for the virus to spread in the fresh air, several cases would have to occur at the same time:
- The distance between the two people is not big enough.
- The virus should have connected to a droplet that remains suspended in the air as an aerosol. (As a rule, the droplets are so heavy that they drop to the ground immediately after being eliminated)
- The viral load in the aerosols should be sufficient to infect another person.
- It would have to be almost windless and the still healthy person would have to inhale the aerosol at this very moment.
Better safe than sorry
In order not to take any risks at all, you should always keep your distance from other people. According to the Robert Koch Institute, there is currently the talk of 1.5 meters. And then your own reason also matters when it comes to the risk of infection.
On weekends, go to the park, where the rest of the city also feels and where you can hardly get past each other on the paths without having to push yourself, please be sensible and better go home. Also, wash your hands at least after every course out of the house.
