Testing for COVID-19 Infectivity (JCM ed.)

How can we determine whether someone who has COVID-19 can transmit the virus to other people? Tests in routine clinical use, such as reverse-transcription polymerase chain reaction and antigen tests, are designed to determine whether SARS-CoV-2 is present or not, but many people have proposed that these tests be used to determine whether a patient is infectious. Furthermore, tests for SARS-CoV-2 that are not routinely used in clinical laboratories, such as viral culture and detection of sub-genomic viral RNAs, have also been discussed as indicators of infectivity. But how accurate are any of these tests for determining whether someone is infectious?
