Effect of Throat Washings on Detection of 2019 Novel Coronavirus

Clin Infect Dis. 2020 Nov 5;71(8):1980-1981. doi: 10.1093/cid/ciaa416.


The 2019 novel coronavirus was detected in self-collected throat washings. The positive testing rate of throat washing was much higher than that of nasopharyngeal swabs. Throat washing is a promising candidate for 2019-nCoV screening and monitoring due to its noninvasiveness and reliability.

Keywords: 2019 novel coronavirus; COVID-19; SARS-CoV-2; oropharyngeal washings; throat washings.
