For those with mild to moderate<unk> , replication-competent virus (i.e., potentially contagious) has not been<unk>  after 10 days following symptom onset. Recovery of replication-competent virus between 10 and 20 days after symptom onset has been documented in some persons with severe<unk> -19 that, in some cases, was complicated by immunocompromised state. However, in this series of<unk> , it was estimated that 88% and 95% of their specimens no longer yielded replication-competent virus after 10 and 15 days, respectively, following symptom onset.
A large contact tracing study demonstrated that high-risk household and hospital contacts did not develop infection if their exposure to a case<unk> started 6 days or more after the case<unk> s illness onset.<unk><unk>  can continue to have SARS-CoV-2 RNA detected in their upper respiratory specimens for up to 12 weeks. Investigation of 285 “persistently positive” persons, which included 126 persons who had developed recurrent symptoms, found no secondary infections among 790 contacts attributable to contact with these case<unk> . Efforts to isolate replication-competent virus from 108 of these case<unk>  were unsuccessful.
Specimens from<unk>  symptomatic<unk>  did not have replication-competent virus detected.
There have been no confirmed cases of SARS-CoV-2 reinfection to date.
Equivalent data from children and infants are not presently available.
