More than 3 in 4 Americans over the age of 16 had COVID-19 as of the end of 2022, according to estimates from the Centers for Disease Control and Prevention.
New federal knowledge of testing from about 143,000 national blood donors found that 77. 5% of respondents had seroprevalence, or COVID-19 antibodies, of an infection before early 2023. That number varies widely from the number of reported COVID-19 cases, which stood at 30 cases consistent with another hundred people at the end of 2022, according to the CDC.
Highest seroprevalence in 2022, with about 48. 8% of blood donors having infection-induced antibodies as of February 15, 2022, according to the CDC. the end of the year.
The antibodies can show up in other people who have already been inflamed or vaccinated, the CDC notes. The study estimates that the country has achieved an overall seroprevalence rate of 96. 7%, adding infections and vaccines, until the end of 2022.
Workplace: Americans are working fewer hours than before COVID. Here’s why.
At the end of 2022, men had a higher infection rate than women, with a 3. 6% difference in infection-induced seroprevalence.
Millennials and Gen Z had higher rates of antibodies to infections, with rates of 87. 1% and 84. 4% for teams aged 16-29 and 30-49, respectively. The population over 65 years of age had the lowest rate at 56. 5%.
Among the races and ethnicities known in the study, the Hispanic population had the highest rate of infection-induced seroprevalence at 80. 6%, and the Asian population had the lowest at 66. 1%. The non-Hispanic white and black populations were roughly equivalent to 77. 4% and 77. 7%, respectively.
Opinion: Sorry RFK Jr. : COVID vaccines work. What to discuss?
The Midwest region had the estimated infections. Iowa, with an infection-induced seroprevalence of 90. 6 percent, had the rate of the 47 states and the District of Columbia included in the study.
The Northeast had the lowest rate, with Vermont having the fewest estimated infections.
