Topic:

  • A seroprevalence study conducted April 28–May 3 in two high-incidence counties in metropolitan Atlanta (n=394 households and 696 people) found an estimated seroprevalence of 3% overall, and 5% among non-Hispanic Black participants. Of those seropositive, 50% reported illness or symptoms consistent with COVID-19, of whom 28% sought care and 16% were tested, demonstrating that many infections would not have been identified through case-based or syndromic surveillance.
