It never ends
New Covid strain is the most transmissible yet, WHO says
The coronavirus Omicron strain XBB.1.5, which has become the dominant strain in the U.S. in just a matter of weeks, could drive a new wave of cases, a World Health Organization official told reporters Wednesday.
“We are concerned about its growth advantage, in particular in some countries in Europe and the Northeast part of the United States, where XBB.1.5 has rapidly replaced other circulating sub-variants,” said Maria Van Kerkhove, the WHO’s Covid-19 technical lead.
Still, health officials are not sure whether that means more people will go to the hospital or die, because of immunity built up by vaccination and prior infection.
What we know: Public health officials have detected the strain in 29 countries, but it could be circulating in many more, Van Kerkhove said.
In the U.S., the sub-variant went from being present in 4 percent of sequenced cases to 40 percent in just a few weeks, White House Covid-19 Response Coordinator Ashish Jha tweeted Wednesday.
But the WHO doesn’t yet know whether XBB.1.5 is more severe than other circulating sub-variants.
You’d think they’d have some idea about the severity after a few weeks if it’s hitting so many people, right?
What’s next: Jha warned that Americans’ immunity against XBB.1.5 “is probably not great” if a prior infection was before July or if they have not received the bivalent shot that became available in September.
He advised people to get their bivalent booster, to test before attending large gatherings or before meeting with elderly or immunocompromised people and to wear a high-quality mask in crowded indoor spaces.
Yes, yes, get the booster, which doesn’t seem to stop people from getting COVID nor from getting a severe case.
Is it normal for a naturally developing virus to have so many strains/variants in such a short time? That it keeps changing?
