Seroprävalenz und SARS-CoV-2-Testung in Gesundheitsberufen

Abstract

The SARS-CoV‑2 causes a disease spectrum that includes asymptomatic and mildly symptomatic infections with subclinical manifestations but which can nevertheless still be potentially contagious. Evidence from SARS-CoV‑2 infected macaque monkeys and from studies with seasonal coronaviruses suggests that the infection is likely to produce an immunity that is protective for a certain period of time. Available test methods enable a high degree of reliability, e.g. if high-quality serological methods are combined. Although individual test results have to be interpreted with caution, serosurveillance in a tertiary eye care center and large eye research institute can reduce anxiety and provide clarity regarding the actual number of (unreported) SARS-CoV‑2 infections.
