A new strain of coronavirus has made the infection even more contagious. Previously, two people could get the virus from one patient, but now their number has increased to four.
"The study in Hong Kong confirmed this trend, as the number of people who are expected to become infected from each infected person has increased from two and a half to three in March to four now," the South China Morning Post quoted Professor and Dean of the medical school of the University of Hong Kong Gabriel Leung as saying.
At the same time, the scientist noted that the increased infectivity does not make the coronavirus more deadly. According to him, the reason for the change in infection lies in a mutation of the most common strain of coronavirus. This mutation made the virus more infectious by almost a third.
In early July, Director of the National Institute of Allergy and infectious diseases of the United States Anthony Fauci said that one of the mutations of the new coronavirus is the g614 strain. This strain is able to multiply quickly and then infect people. He stressed that it was G614 in Italy that infected more than 240 thousand residents. However, in Wuhan, where the infection started, there was a different strain.
