Study Shows CT Had Six Times the Number of COVID-19 Infections Originally Reported

Connecticut had at least six times the number of people infected with COVID-19 as the state reported — an estimated 167,700 residents infected by the disease at the beginning of May, the Centers for Disease Control and Prevention said today.

The CDC said its first antibody study of 1,431 Connecticut residents indicated that nearly 5% of the state’s population had antibodies to COVID- 19 at the beginning of May. Connecticut was the second-highest of five states tested for antibodies in the agency’s first study. Only New York showed a higher rate of infection, nearly 7%.

The blood samples in Connecticut were taken from April 26 to May 3. On May 3, the state reported that 29,300 residents had tested positive for the coronavirus, about one sixth of the infections the antibody tests discovered.

The CDC partnered with commercial laboratories to conduct a large-scale geographic seroprevalence survey that tested for COVID-19 antibodies in clinical blood specimens from Connecticut, South Florida, the New York City metro area, Missouri, Utah and Western Washington State.

The survey includes people who had blood specimens tested for reasons unrelated to COVID-19, such as for a routine or sick-visit blood test by commercial laboratories. The. CDC aims to test about 1,800 samples collected from each testing area about every three to four weeks to determine what percentage of people tested already have antibodies against COVID-19, and how that percentage changes over time in each area.

The CDC plans to expand the survey to an additional four states, including California, Louisiana, Minnesota, Pennsylvania and Utah.

Increased use of antibody testing will provide a snapshot of how many Americans actually had the disease even when they did not think they ever had it, experienced few or mild symptoms or no symptoms at all.
