A new dominant omicron strain in the U.S. is driving up cases — and reinfections

"The BA.5 variant is now the most dominant strain of COVID-19 in the country, according to the Centers for Disease Control and Prevention. And while it's hard to get an exact count — given how many people are taking rapid tests at home — there are indications that both reinfections and hospitalizations are increasing. Dr. Bob Wachter, the chair of the Department of Medicine at the University of California, San Francisco, says BA.5 is highly transmissible and manages to at least partially sidestep some of the immunity people may have from prior infections and vaccinations."
