• A study of antibody responses after COVID-19 infection in patients in Bangladesh indicated that while people who had mild symptoms generated an immune response, those who had no symptoms had lower antibody levels or did not generate any detectable immune response. IgM and IgA responses developed by day 14 after confirmation of infection in 72% and 83% of individuals with mild symptoms, respectively, and 100% of them developed IgG responses by day 30. In contrast, people without symptoms developed antibody responses significantly less frequently, with only 20% positive for IgA and 22% positive for IgM by day 14, and 45% positive for IgG 30 days after infection.
