Those who recovered and are asymptomatic might still be able to spread COVID-19

This report, from Wuhan, China describes the growing realization that a subset of infected individuals may continue to shed SARS-CoV-2 (COVID-19) virus weeks to months after symptomatic recovery from COVID-19 the infection.

 

This report, from Wuhan, China describes the growing realization that a subset of infected individuals may continue to shed SARS-CoV-2 (COVID-19) virus weeks to months after symptomatic recovery from COVID-19 the infection.

While the implications of this finding are not clear, they raise the possibility that a subset of patients who have had the infection and recovered may be able to infect others long after symptom resolution.

In China, the current recommended period of isolation after COVID-19 exposure is 14 days and hospitalized patients who recover and remain asymptomatic are discharged after two negative nucleic acid tests (swab tests), taken at least 24 hours apart.

What are the clinical and public health implications of these new finding that individuals have persistent viral shedding after symptom resolution?

The answers to these important, yet unanswered questions will impact individuals, families, and public health policy. These findings support the need for continued ongoing testing in groups of people to detect asymptomatic shedding both from new cases and those who recovered from COVID-19 infection in the past.
