Abstract:
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.
