The site takes a strict approach, according to its founder, Joshua Weitz, as a person is supposed to remain contagious for ten days, while other researchers believe that this period ranges from 5 to 6 days, although viral deposits remain later. .
The approved model does not take into account that the person infected with the virus will probably stay at home and will not participate in the event after symptoms appear, since its authors base that most infections are caused by people who do not have symptoms to a great or absolute degree, or they are unaware of their infection.

And this equation says for those who want to assess the risks: “If there are ten people at the same table, the risk that at least one of them will be infected with the virus is 32 percent in Paris, 18 percent in Washington. and 58 percent in Prague, for example. “
This math is simple. It is based on recent data on the spread of the “Covid-19” epidemic, presented in an easy-to-read manner on a website that has been increasingly successful since its inception in July at the initiative of researchers at the Georgia Tech Institute at United States.
The methodology adopted to assess the risk of transmission was endorsed in an article published in the prestigious journal “Nature”.
The “Covid-19 Risk” website, available in English, was the victim of its success on Thursday, due to the large number of visits it received and messages indicating that an error sometimes appeared.
Researchers assess potential risk based on the official number of cases counted each day at a given site.
The model also takes into account that the actual number of infections is five to ten times greater than the total number of positive diagnostic tests.
A user can base one of these two assumptions (5 or 10 times) on his calculations.
Meanwhile, the percentages take into account the assumption that the risk is 10 times higher.
The user can also choose the size of the event while specifying the number of people expected to participate in it, be it 10, 25, 50 or one hundred, up to 5,000.
