Two meters apart. Put on the gags. These are generally useful tips, but two people have no idea where they will be infected with the new coronavirus. According to a study by vdc from Great Britain and the USA, we compiled an interactive tool. Easily find out what increases the risk of infection and how to dream it.
Rising sweat caused by covid-19 disease in the world and in the Czech Republic is leading to new ways of slowing down infections without introducing paralyzing measures. One such trip is offered by the British-American team in a study published in late August in the prestigious BMJ scientific journal. We present their tweaks in the following interactive graphics.

The clem chart is shown relative risk. Described activities are selected types,
specific circumstances may cause the virus to rise or fall sharply.
The scientists took care of the mistake that the virus was only at such a distance as the droplets.
A distance of two meters may not be enough
It had droplets as dark as aerosols, it looks two, they do not fall to the ground, warn. When retracting or sweeping, the droplets can reach a distance of seven and eight meters in a few seconds.
The danger of contagion is influenced by a number of factors, which are nicely combined, swells and researchers. How much risk do you take when you are in a group of people and no one shows symptoms of the disease? Bad environment, on whether the people have worn pipes, on ventilation, concentration of people, volume of communication and its duration, the leaders enumerate the basic factors.
The table showing the relative degree of risk on the basis of five factors: environment, number of people, volume of communication, hands and duration of contact.
The study of sciences, published in BMJ, also received known attention thanks to the color chart. We have prepared for it an esk translation (available in PDF).
Scientists at the table emphasize that this is a relative estimate, not an absolute strength: The factors do not include the presence of hardening and quenching people, which increases the danger. He gave a variable, which is not included in the overview, is the susceptibility of specific people to infection, or two viruses in the droplets.
The humidity of the environment in particular plays a role, but the ride was not proven, the scientists noted. And finally, only those situations where someone who is infected with the virus is mentioned are at risk. This is due to the fact that the virus can be found in an individual without symptoms, usually cannot be detected in advance.
The distance of people from each other must be part of the strategy, leading to the study. It must take into account factors such as the number of people, the air flow, the concentration of people and personal protective equipment such as handkerchiefs. According to you, a comprehensive understanding of how the virus and what increases the risk of infection is likely to lead to a possible return to normal social and economic life.
