A variant probably more contagious than the rest of the Sars-Cov-2, to the point that some researchers believe that it would be more dangerous than a virus which would be less contagious but more … deadly. Illustration with epidemiologist Adam Kucharsky, from the London School of Hygiene & Tropical Medicine, who carried out this type of demonstration on Twitter, supporting calculations: “The key message is that an increase in something that grows exponentially (i.e. transmission) can have a much more effect than the same proportional increase in something that only increases a result (ie gravity). “ In other words, between two strains – one more lethal, the other more transmissible – it would be the most transmissible strain which would quickly do more damage …
