Sample Pooling as a Strategy to Detect Community Transmission of SARS-CoV-2
Category: Article Summary
Topic: Testing and Treatment
- The authors used sampled pooling, a strategy used for community monitoring of other infectious diseases, in this retrospective study to increase overall testing efficiency at an expected slight loss of sensitivity.
- 292 pools were screened, corresponding with 2740 nasopharyngeal samples and 148 bronchoalveolar lavage samples, collected from inpatients and outpatients between Jan 1-Feb 26 in the San Francisco Bay area. Results suggest that pooled screening may facilitate detection of early community transmission of SARS-CoV-2 and enable timely implementation of appropriate infection control measures to reduce spread.
