The SARS-CoV-2 coronavirus seems like a bad movie saga, with sequels that do not stop emerging. The latest novelty comes from the United Kingdom, with the highly contagious XE recombinant variant, a mixture of BA.1 (ómicron) and its subvariant BA.2.
“At the moment, there really isn’t any public health concern,” said John Brownstein, an epidemiologist and chief innovation officer at Boston Children’s Hospital. “Recombinant variants are produced over and over again,” he told abcnews.
According to the expert, “the reason that this is the XE recombinant variant is that we have already had XA, XB, XC, XD, and none of them have turned out to be really worrisome”. In other words, these mixtures are common and they are extinct as fast as they appear.
Appeared on January 19, 2022 in the United Kingdom, the Health Security Agency reported a total of 637 cases of the XE variant in the penultimate week of the third month. What’s unsettling is that it might be “slightly” more transmissible than BA.2, by about 10 percent.
At the World Health Organization (WHO) they assured that “it continues to closely monitor and evaluate the risk to public health associated with recombinant variants, along with other mutations” of the coronavirus causing the worst pandemic in more than a century.
As of the closing of the edition of this note, more than 490 million people had been infected with SARS-CoV-2 since the end of 2019. The count of the Johns Hopkins University established 6.1 million fatal cases as a result of the disease.
