Do varieties cause the disease to last longer?



Olivier Verne announced at a news conference Feb. 18 that the isolation period for a positive test for the new coronary virus would be seven to ten days from Feb. 22. A decision justified by the Minister of Health citing “certain studies” showing that different variants of Kovid-19, identified since the beginning of 2021, prolong the transmission period of the disease.

What is it about? From the end of January the first questions arose as to the breeding season of these varieties, which have been identified in the United Kingdom, South Africa or Brazil. In an article, magazine National Geographic “Some mutations (…) can infect humans for a long time,” he said.

The first British public health study, in collaboration with the University of Birmingham, found that viral weight, virus size in the body. B.1.1.7 strain is more prevalent in infected individuals, Commonly known as the “British” variety. The increase in the incidence of infectious diseases and UK cases of this mutation is a possible explanation.

But another study released on February 16 and signed by researchers at various major American universities points to another explanation: whether the virus load is B.1.1.7 variant or some other variant of Kovid-19, it will be “similar”. . But The duration of infection increases.

An isolation period has already changed

According to the researchers, this was the average time of infection 13.3 days for the variant and 8.2 days for the other variants. This study has not yet been evaluated by other researchers, and one author a Tweet, Only seven instances of the variant have been studied.

Isolation time has been reduced to 14 days in September for individuals who initially tested positive for 14 days. In the absence of a variant, the Minister of Health explained that the contagious disease was “more than a week old but still present, but very rare.”
