Results: Immune Response to SARS-CoV-2 in Health Care Workers Following a COVID-19 Outbreak

In baseline testing at $2$ - $3$ weeks, $48%$ of Covid-19 patients had a positive IgG response, and at $8$ - $12$ weeks, 77.8% had a positive response. - The majority ( $72%$ ) of patients showed an increase in IgG levels between the baseline and follow up testing. Those who had contact with infected individuals but never developed Covid showed no positive IgG levels at follow up testing. - For IgA response, $76%$ of Covid patients showed elevated levels at baseline, but only $32%$ showed elevated levels at the follow up. And, some patients with no IgA levels at baseline still later developed IgG levels at the follow up.
