This is characteristic of viruses: they evolve, mutate, change… nothing exceptional on the horizon. But while the Covid-19 pandemic continues to claim victims, the emergence of new variants is under scrutiny more than ever. A third seems to have been born, this time in California… and it is said to be very common in the US state.
CAL.20C: the Californian variant of Sars-CoV-2
The discovery was made rather by chance, as is the case in this type of situation: while they were looking for the presence of the British variant of the Sars-CoV-2 virus in December 2020, a variant which they found in the cases tested positive, the researchers identified a new version of the virus. Called CAL.20C, it is the third confirmed major variant.
According to the researchers, the first cases of this new variant actually appeared in July 2020, but it was not until November 2020 that its spread increased. Now, it accounts for nearly half of new Covid-19 cases in the US state, a situation which does not fail to recall that which the United Kingdom is facing with its British strain, having led to an increase in cases such that the country has been confined since the beginning of the year 2021.
A variant that is again more contagious?
The researchers are worried about this new variant, the origin of which they are trying to understand, but also the impact on the pandemic: is it more deadly or more contagious than the classic variant of Sars-CoV-2 or the British variant, called B.1.1.7?
In any case, it seems to be spreading all over the United States, the strain having already been identified in several American states such as Washington, Nevada, Texas or even Arizona.
Information that should consolidate Joe Biden in his decision to counter the reopening of flights to the United States, announced by Donald Trump for January 26, 2021, against all expectations, and to which he is opposed.
