Interpreting Diagnostic #Tests for #SARS-CoV-2 | Infectious Diseases | JAMA | JAMA Network
Using available evidence, a clinically useful timeline of diagnostic markers for detection of #COVID-19 has been devised (Figure). Most of the available data are for adult populations who are not immunocompromised. The time course of #PCR positivity and seroconversion may vary in children and other groups, including the large population of asymptomatic individuals who go undiagnosed without active surveillance. Many questions remain, particularly how long potential immunity lasts in individuals, both asymptomatic and symptomatic, who are infected with SARS-CoV-2.
