May 7, 2023 · It's about 1.2 times more infectious, more transmissible, than prior variants. So what we're going to see is, over the next several months and into the summer, this will become the dominant ...
Jun 14, 2022 · BA.4 and BA.5 may be the most transmissible versions yet. In some countries, those subvariants are replacing BA.2 roughly as fast as BA.2 replaced the original Omicron, the U.K. Health Security ...

Unlike what its nickname might suggest, the BA.2 subtype isn't known as "stealth" omicron because it's difficult to find. The nickname comes from a shortcut that helped researchers quickly identify omicron in PCR tests. Because of a quirk in omicron's genetic sequence, PCR test results looked different from typical positive tests, essentially provi...
The BA.2 subvariant most likely evolved as omicron circulated widely around the world. As a virus spreads and replicates, it naturally picks up random mutations that can change how it behaves, such as how contagious it is or how severely it can make people ill — although many mutations won't change how the virus affects humans. It's too soon to kno...
Preliminary research in Denmark, where cases involving BA.2 are rising, suggest that the subvariant may be more contagious than the original omicron strain, which was already the most transmissible known variant to date. The BA.2 subtype accounted for 20 percent of Denmark's Covid-19 cases at the end of December, and it jumped to 45 percent of repo...
So far, there is no evidence to suggest that the subvariant causes more severe illness or symptoms, but it may be too soon to tell. Danish health officials said in a news briefing Wednesday that while the BA.2 subtype seems more contagious, there are no indications that it has an impact on hospitalizations or deaths. Still, hospitalizations and dea...
More research is needed, but early reports show that vaccines are roughly as effective against BA.2 as they are against the original strain of omicron. While omicron's mutations allowed it to better evade protective antibodies generated by vaccines and natural immunity, the vaccines and the booster shots protected the vast majority of people from b...
The omicron subvariant has been identified in several countries, including Denmark, the United Kingdom, Norway, India, the Philippines and South Africa. In the U.S., BA.2 accounts for an extremely low percentage of newly reported cases, but it has already been detected in California, Washington, New York, Texas, Utah, New Mexico and other states.
Sep 1, 2023 · Except in rare cases, the original version of Omicron is no longer circulating—neither is the original strain of the SARS-CoV-2 virus and the early, more severe Alpha and Delta variants. But, as of early September 2023, CDC estimates showed a long list of circulating Omicron subvariants, including more than a dozen XBB strains.
