Oomikroni alamvariant BA.2.75 "Kentaur" USA-s kohal:
Just one week after BA.5 had outcompeted all other Covid strains become dominant in the U.S., a new highly-mutated Omicron subvariant has arrived which may begin the cycle all over again.
BA.2.75 has a large number of mutations when compared to its sister Omicron lineages. Some of those adaptations could allow the virus to bind onto cells more efficiently, said Matthew Binnicker, director of clinical virology at the Mayo Clinic in Rochester, Minnesota. BA.2.75 was first sequenced in May in India, where it has spread rapidly.
A very early analysis of data from India by Raj Rajnarayanan — who is Assistant Dean of Research, NYITCOM at Arkansas State University — indicates that BA.2.75 may have a growth advantage over BA.5. It is unclear, as yet, whether BA.2.75 makes people sicker than previous variants.[...]
Since it was first identified, the subvariant has been spotted in “about 14 countries,” according to WHO Covid-19 Technical Lead, Maria Van Kerkhove. Those include Australia, Canada, Japan, Germany, New Zealand, the United Kingdom and the U.S.
