Topic: Transmission
- Yong et al describe how active case finding and contact tracing were used to identify cases and establish links between three clusters of COVID -19 in Singapore. The investigations used both SARS-CoV-2 serological assays and traditional epidemiological methods to confirm transmission between cases. This study is important to those establishing links among locally transmitted COVID-19 cases and tracing the transmission chain to an imported or initial source.
