Although the COVID-19 disease was expected to have been cured, there are a lot of infected individuals in the world who showed a positive response again for SARS-CoV-2 infection through PCR. The viral load detected in asymptomatic patients was similar to that in the patients demonstrating COVID-19 symptoms. In addition, PCR testing using stool samples rather than nasopharyngeal swab samples may be necessary to determine SARS-CoV-19 infection. Experts in viral infections are paying close attention to these features of SARS-CoV-2. In this Review, issues and improvements related to PCR testing for COVID-19 will be described along with new findings.
