Omicron strain cases rise in the United States

LA CROSSE (WKBT) — The COVID-19 pandemic is still infecting people across the globe and the Omicron subvariant BA.5 is to blame.

It is estimated to have caused 82 percent of cases in the United States due to the virus’ high transmission rate.

However, Doctor of Laboratory Medicine and Pathology at Mayo Clinic Health System Matthew Binnicker says that’s not the only reason BA.5 is the most dominant Omicron strain.

“It also has some properties of what we call immune evasion that allow the virus to sidestep some of the prior immunity from either vaccination or previous infection,” he said.

Omicron has also mutated into a strain called BA.2.75, which hasn’t caused a high number of cases in the U.S.

However, it’s possible the strain could infect more Americans in just a matter of months.

Scientists hope to make an additional vaccine that will protect against both strains of Omicron.
