Background: Elucidation of the chain of disease transmission and identification of the source of coronavirus disease 2019 (COVID-19) infections are crucial for effective disease containment. We describe an epidemiological investigation that, with use of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serological assays, established links between three clusters of COVID-19.
Methods: In Singapore, active case-finding and contact tracing were undertaken for all COVID-19 cases.
Article Synopsis
- Three COVID-19 clusters were identified in Singapore in February 2020, linked to a Chinese tour group, a corporate conference, and a church.
- Researchers collected clinical and epidemiological data to understand transmission modes and found that 36 cases were connected to these clusters, with a median incubation period of 4 days.
- The study highlights the need for enhanced surveillance and contact tracing in areas with high travel from China to prevent widespread COVID-19 transmission.
