5 Percent Of CT Residents May Have Had Coronavirus: CDC

A total of 185,000 people in Connecticut may have contracted the coronavirus, more than four times previous estimates, the CDC said.

CONNECTICUT — Around 5.2 percent of the state’s population may have contracted the coronavirus as of late May, according to a Centers for Disease Control and Prevention antibody survey. That equates to around 185,000 potential cases in Connecticut, which is more than four times the amount of cases identified at the time.

The CDC said the survey showed between 3.8 and 6.6 percent of the Connecticut population have been infected with the virus at some point.

The CDC partnered with commercial testing labs to estimate infection levels for four states and a handful of large cities. Around 23 percent of New York City residents have antibodies for the virus as of late May, according to the CDC.

The survey was the second of its kind from the CDC. The first also included Connecticut and estimated an infection rate of 4.9 percent as of May 3.

The second survey was conducted between May 21 and 26. It included people who had blood samples collected for reasons unrelated to COVID-19, including routine medical visits. A total of 1,800 Connecticut samples were collected.

The survey found around 5.8 percent of women and 4.6 percent of men in Connecticut were infected.

The CDC notes the survey comes with some caveats. It isn’t random and relies on people whose blood was taken for routine screening or sick visits, which may not reflect the population as a whole.

The results reported by the CDC are adjusted for false positive and false negative results. The CDC notes that it is possible that antibody levels may decrease over time and that people who previously tested positive for the presence of antibodies may at some point test negative.

The CDC also warns that the survey shouldn't be interpreted to mean people who tested positive for antibodies are immune to the virus. It is still unknown how long antibodies last and what level of protection they offer.
