A highly mutated Covid variant, feared to be better at infecting vaccinated people than previous variants, has now been detected in a third state.
The BA.2.86 strain was picked up through wastewater testing in Ohio, the state’s health department announced Wednesday, after the variant was detected in Virginia and Michigan over the past week.
Further analysis by the Centers for Disease Control and Prevention (CDC) is underway to confirm that the Ohio sample is the new strain, also known as “Pirola.”
The CDC announced Wednesday that it believes “the large number of mutations in this variant raises concerns about greater escape from existing vaccine immunity and previous infections compared to other recent variants.”
It comes as the number of Covid hospitalizations in the US has risen 22 percent in one week, the fifth week in a row that they have increased. The CDC is now predicting an acceleration in the number of new hospitalizations in the coming month.
According to the Centers for Disease Control and Prevention (CDC), about 2,000 Americans are hospitalized every day.

The CDC forecast supersedes a previous projection that recordings would “remain stable or show an uncertain trend.”
The forecast, released Mondaysuggests that about 2,000 Americans are hospitalized every day, the vast majority of whom are over the age of 65.
Hospital admissions are still three times lower than at this time last year, and mortality rates are still very low.
Doctors on the ground also say the illness is the mildest they’ve seen in Covid patients during the pandemic.
Still, concerns about the new variants have led to masks creeping back into everyday life.
A Kaiser Permanente hospital in Santa Rosa, California and Upstate Community Hospital in Syracuse, New York, which together serve millions of Americans, have reduced mandates for doctors, nurses, patients, and visitors.
Ken Gordon, a spokesperson for the Ohio Department of Health (ODH), shared this CBS news the department “worked with the CDC on further evaluation of the sample,” but added that the “preliminary detection has not (yet) been confirmed.”
Wastewater is tested as part of routine monitoring for the National Wastewater Monitoring System.
Positive wastewater tests can detect old cases, but can also signal new cases.
Since the end of the pandemic, the number of people taking Pap smears has been very low, with only a handful of these being analyzed for variants.
The BA.2.86 strain is highly mutated and potentially has a higher chance of infecting vaccinated Americans, the CDC said yesterday.
The stain has more than 30 mutations in the spike protein — the part the virus uses to infect humans — that sets it apart from currently dominant strains, and is expected to make it more difficult for the immune system to recognize in vaccinated or previously infected individuals. people.
It may also be more likely to cause illness in people who have recently recovered from a Covid infection.
“The large number of mutations in this variant raises concerns about greater escape from existing vaccine immunity and previous infections compared to other recent variants,” the CDC said in its risk assessment of BA.2.86, which has been dubbed the “Pirola.” named. variant.
However, the agency said it was too early to know if this will cause a more serious infection than other variants and appears confident in its assessment that levels of immunity in the US population will still provide broad protection.
“Almost the entire U.S. population has antibodies to SARS-CoV-2 due to vaccination, previous infection, or both, and it is likely that these antibodies will continue to provide some protection against severe disease from this variant,” the CDC said.
DailyMail.com revealed on Tuesday that the variant had been detected in a patient in Virginia, marking the second official case after being diagnosed last week in a Michigan resident.
However, the CDC said that because so few smears are analyzed now, the strain is likely much more widespread than official numbers indicate.
And the Covid positivity numbers – the proportion of Pap smears that come back positive – almost doubled between July and August.
The CDC said the current increase in U.S. hospitalizations is unlikely to be caused by BA.2.86. because of the delay it takes for people to catch Covid and then get sick.
This new BA.2.86 strain is believed to be descended from the BA.2 ‘stealth’ variant which took off worldwide early last year and which itself is a spin-off of the original Omicron strain.
The updated Covid vaccines – due to be released this fall – target strains descended from the XBB Omicron subvariant, which has become the dominant type worldwide.
The CDC said researchers are evaluating the effectiveness of the updated admissions, which are expected to reduce serious illness and hospitalizations.
Compared to other strains descended from the Omicron subvariant, BA.2.86 has many more mutations.
The CDC compared the differences between it and its probable ancestor BA.2 as similar to the difference between the Delta and Omicron variants.
“The large number of mutations in this variant raises concerns about greater escape from existing vaccine immunity and previous infections compared to other recent variants,” the CDC said.
“For example, an analysis of mutations suggests that the difference may be as great or greater than that between BA.2 and XBB.1.5, which circulated nearly a year apart.”
“However, virus samples are not yet widely available for more reliable laboratory testing of antibodies, and it is too early to know the true implications for immunity.”
