Connecticut’s COVID cases have been rising throughout the summer, reaching levels in August not seen since February, according to the Department of Public Health.

COVID cases in Connecticut remained relatively stable from March through early July, before rising in late July and August. Hospitalizations from COVID, which remained low throughout the summer months, also rose in August.

“Anecdotally, I’ve been hearing about more cases, and the data also always lags behind what’s actually happening,” said Manisha Juthani, commissioner of the Department of Public Health.

While half as many cases were reported in August 2025 as August 2024, case numbers are, in part, a function of how many people choose to get tested.

“Not every COVID case is being reported to us. So if somebody goes to an urgent care, or maybe just does a self test, we won’t get that data,” Juthani said.

On Wednesday, Gov. Ned Lamont released a statement encouraging all adults, and children older than 6 months, to get a COVID-19 booster shot.

Wastewater surveillance, which tests for COVID-19 concentration in wastewater, saw an increase in late July and at the end of August, otherwise remaining low through the early summer.

“I don’t really know if [COVID cases are] coming down, or if this is going to be part and parcel of the beginning of an early fall into winter increase,” said Juthani. “I think that remains to be seen.”
