In the Spanish region of Asturias, several cases of Covid could come from a new strain of the virus, very similar to BA.4 and BA.5.
For several days, theSpain remains on alert after an upsurge in the number of contaminations. If the country still seems to have the pandemic under control within its population, the discovery of cases potentially carrying a new strain of Covid worries the authorities.

In Asturias, researchers are asking themselves
This Tuesday, May 3, El Periodico revealed that the microbiology laboratory of the Central University Hospital of Asturias (HUCA) had identified at least 5 cases of a possible new strain of the virus. According to the researchers, the patients would be positive for the subvariants BA.4 Where BA.5present in South Africa.
However, they say he “there is no evidence that the carrier patients have any relationship with those in South Africa”. The geographical proximity of the cases, all identified in the same region, encourages scientists to consider “a specific evolution of the virus in Asturias”which could lead to “an aboriginal variant”.

New variant or simple new cases of BA.4 and BA.5?
For now the possibility of a new variant originating from Asturias remains at the hypothetical stage. The researchers are certain, however, that it is a different strain from those currently circulating in Spain, such as the BA.1 where the BA.2.

It is in particular the accumulation of cases that remains unpublished. There would currently exist 5 proven cases, as well 6 probable cases and 3 doubtful.
The Spanish scientists are therefore continuing their research and explain that they will be able to find out more by the weekendwith the arrival of new cases and the help of the international database.
According to the Spanish researchers, it does not appear that this potential new variant could change the course of the pandemic. However, if it really is a new variant, this strain could make it possible to readjust the vaccine current.
Generally speaking, this strain would be even more transmissible than the original version of the Covid variant Omicron. However, the symptoms related would not be of particular concern since none of the patients were hospitalized.
