Eight Connecticut municipalities are currently in the COVID-19 red-zone alert level, according to data released March 24 by the state Department of Public Health.

Fairfield, Goshen, Guilford, Middletown, New Haven, North Haven, Weston and Westport each reached the red-zone baseline of 15 cases per 100,000 people in the two-week period ending March 19. Westport, with 25.1 cases per 100,000 people had the highest daily rate in the state. Red is the highest level of four color-coded zones.

More than half of all tested COVID-19 cases in New England are now linked to an Omicron subvariant called BA.2, according to the Centers for Disease Control and Prevention. Much of the state’s municipalities remain in the lower-alert zones. The daily test positivity March 24 was 2.64 percent.

Here is how the DPH calculated the risk of being unvaccinated (compared with those vaccinated):

  • 3 times higher risk of being infected.
  • 9 times higher risk of being hospitalized.
  • 4 times higher risk of dying.

Those who have been infected with COVID-19 also figures into the risk.

“Absolutely, there is definitely some sort of herd immunity with natural immunity and vaccinations and boosters as well,” says Dr. Ulysses Wu, Hartford HealthCare’s System Director of Infection Disease and Chief Epidemiologist. “But all of that is waning at this point.”
