Coronavirus Infection, Vaccination and School Cases: Town-By-Town

CONNECTICUT — There are only three holdouts against the red tide that has washed over the state in the final weeks of 2021.

Norfolk, Canaan and Roxbury have all reported less than five cases of COVID-19 per 100,000 residents. The rest of the state is in the high-alert red zone, according to data released from the state Department of Public Health.

The color codes correspond to guidance from DPH. Populations in the red zone have reported 15 or more cases per 100,000 people over a two-week average.

Mansfield remains the vaccination outlier, still with just over 40 percent of its population fully vaccinated. Of all Connecticut municipalities, only Canaan, with its population of 1,053, has fully vaccinated all its residents.

The graph above illustrates the slow progress toward complete vaccination.

As of Thursday, those residents who have received at least one dose of the vaccine against COVID-19 include more than 95 percent of those over the age of 55, 87 percent of those between 45-54, 89 percent of those between 35-44, 82 percent of those between 25-34, 76 percent of those between 18-24, 82 percent of those between 16-17, 74 percent of those between 12-15 and 32 percent of those aged 5-11.

The table below shows cases and deaths among fully vaccinated persons by age group.

As of Thursday, 43,337 cases of COVID-19 among fully vaccinated persons in Connecticut have been identified. Of the 2,490,677 persons who are fully vaccinated, 1.74 percent have contracted the virus.

Two hundred fifty-six COVID-19 related deaths have occurred among the 43,337 fully vaccinated
persons confirmed with COVID-19. These deaths represent 16.2 percent of all COVID-19 deaths since February 9, 2021.

The charts above and below show the "relative risk," or the difference in risk when comparing rates between vaccinated and unvaccinated persons.

The latest data show unvaccinated residents have a 13 times higher risk of dying from the coronavirus, compared to the vaccinated. Their risk of hospitalization is also 13 times greater, and the risk of infection is 4 times as great.

Although coronavirus deaths in Connecticut have declined markedly since February, it is important to note that death — and hospitalization — rates have consistently been higher among unvaccinated persons compared to fully vaccinated persons.

During the week of Dec. 16-22, 753 Connecticut schools reported coronavirus cases among either students or staff.
