To keep a distance of one to two metres behind the people who are have been shown to be an effective smittetiltak.
But if the person in front of you walking, bicycles or jogging should be a safe distance to be longer, suggests research from the University of Leuten and Eindhoven University of Technology.
Scientists believe that distances of under 20 metres may be too small if you are behind a cyclist.
It is necessary to point out that this has not been validated research and that there is inadequate information about, among other things the methods that are used.

the Reason is that the infection can become caught in the person’s so-called “slipstream” or dragsug on the Norwegian, and the faster the person moves, the longer is the flow of air.
Whether you are out on the run or leisurely bike ride, believes the study is that the distance should be ten feet. If you are looking at a “hard” cycling, is a safe distance of 20 metres.
risks of infection: the Acting director Svein Lie tells us that tometersregelen still current, and that it included a certain amount of risks of infection when jogging or running.

Svein Lie, acting director, seems the belgian-Dutch study is interesting and something the ministry of Health should look closer at. He also points out that there is a certain risks of infection when people are out and “‘m panting and sweating”.
– But then it is important to say that the vast majority of smittesituasjoner seems to have happened in the close contact between people, at home or other places. So still, we think that the council to keep two metre distance and not be dense in groups is the most important.
– Should avoid to lie behind recreational
the ministry of Health writes that koronaviruset found in the tiny droplets that come out through your mouth and nose when an infected person coughs or sneezes.
The most common method of transmission is that you breathe in droplets of infection which float in the air or that you get the virus on your hands and get it in you if you are taking you in the face, they write on the helsenorge.no.
– If you breathe out or cough while you are out jogging, remains the drops in the air. The person running behind you in the so-called slipstream then goes through the cloud of droplets, ” says Bert Blocken, professor of aerodynamics at the KU Leuven and Eindhoven University of Technology to HLN.
In sports such as cycling and running exploits athletes slipstreamen from the competitor in front to their advantage. By using methods and models from this sport’s world, the researchers looked at how the infection can become caught.
They conclude that the risk of being hit by spyttpartikler from the person in front is greatest if you end up in their slipstream. In other words, is it better to jog or cycle by the side of each other than the rear and in front of each other.
Based on the findings recommend Blocken to keep a distance of at least four to five meters to the person walking in front of you.
the Whole the preliminary report named “COVID-19 Social Distancing v2.0: During Walking, Running and Cycling” has been made available on the web.
the Study is not peer reviewed
Simulations show that distance does not play so big role for the two persons moving side by side in calm weather. Those moves diagonally one behind the other have also less likely to be hit by spyttpartikler from the person in front.
On his own Twitter account writing Blocken that the analyses have been done without the headwind, tailwind or crosswind. According to the English newspaper The Guardian is not the study peer reviewed.
considering the situation, we decided that it would be unethical to keep the results confidential and let the audience wait several months on that fagfellevurderingsprosessen was completed, says Blocken.

According to VICE react to a epidemiolog at Harvard University that the study, which is not completed and has not been validated, now has received attention the world over.
– This study is not very useful for us science. It is disturbing how quickly this investigation has gone viral, ” says William Hanage.
There are still a lot of uncertainty related to how well koronaviruset spreading in the air.
– Must be practical also
1. april, the ministry of Health with a general guide for sport, which says that it can be arranged for idrettsaktivitet in smaller groups up to five people.
at the same time recommend the Norwegian cycling federation has all of its members that all sykkelaktivitet outdoor happens alone, and not in groups, because of the great danger of dråpesmitte.
the Acting director Svein Lie does not think the council about the safe distance of two meters will be changed with the first.
– I think that we must have a safe distance within what is feasible also. So people can make sure they are not too close into each other when they are out and bike or jogging next to each other.
