BOSTON — State health officials reported nearly 4,000 coronavirus breakthrough cases last week, another increase from the previous week while fully vaccinated hospitalizations ticked up.
The count of 3,892 breakthrough infections last week was a 43% jump from the 2,732 fully vaccinated cases during the prior week.
The once-surging omicron variant had been retreating during the last several weeks, but health experts are now warning of the omicron BA.2 “stealth” variant. The Boston-area COVID-19 wastewater data recently started to rise again. State health officials have been encouraging people to get a booster shot to get more protection from the variants.
