Scientists are keeping a close eye on a new version of the COVID 19 omicron variant. The new variant, referred to by researchers as BA2, is a descendant of the omicron mutation. At least three cases have been reported in the U. S.. They were found in patients at Houston Methodist Hospital in Texas, where researchers are studying samples of the virus.
The new version appears to have similar traits as the original, such as its apparent ability to evade preexisting immunity, whether from the virus or from vaccinations. BA2 has also been dubbed as “stealth omicron”, according to the Washington Post, because its genetic traits make it difficult to detect with a PCR test, which could detect the original version or the variant. The U-K Health Agency reported cases of BA2 have been detected in 40 countries and was first reported in the Philippines. It is the dominant form of the virus in Denmark. Scientists say there is still much to learn about the new version. As of right now, there is “insufficient” evidence that it causes more severe illness or is more contagious than the original omicron variant.
