COVID Keep your distance after some one near your recovers


At the moment you are being told to hiberate for 7-14 days with suspected issues, but this work is just to warm you that people may have virus for a few days after they seem to be recovering, so maintain your social distancing. People shed virus for a variable amount of time. I haven’t got time to do a full post. Obviously this data was from moderately ill people and people with milder disease may be OK but better to safe than sorry.

Likewise detecting virus does not mean it is infective.

Li Y, Hu Y, Zhang X, Yu Y, Li B, Wu J, Wu Y, Xia X, Xu J. [Follow-up testing of viral nucleic acid in discharged patients with moderate type of 2019 coronavirus disease (COVID-19)]. hejiang Da Xue Xue Bao Yi Xue Ban. 2020 May 25;49(1):0. Chinese.

OBJECTIVE: To investigate the clinical outcome of patients with moderate type of corona virus disease 2019 (COVID-19) after discharge by retesting viral nucleic acid.

METHODS: Seven patients with moderate COVID-19 met the discharge criteria enacted by National Health Commission were quarantine in hospital for 7 days, then continuously quarantined at home for 4 weeks after discharged. During the three weeks of quarantined period, the symptoms and signs were documented; and sputum or nasal swab and feces samples were collected to test SARS-COV-2 nucleic acid by RT-PCR method.

RESULTS: There were no symptoms and signs during the quarantine period in all 7 patients. However, respiratory swabs from 3 patients were confirmed positive of SARS-COV-2 nucleic acid at 5 to 7 days after they met the discharge criteria.

CONCLUSIONS: The study indicates that there is a relatively high incidence of positive viral nucleic acid in patients met the discharge criteria, and it is suggested that patients met the current discharge criteria should be quarantined in hospital for another 7 days and the follow-up viral testing is necessary.

About the author



  • But Prince Charles had a positive test 7 days ago and now he’s back out and about ?! Surely our guidance is wrong from govt ?

    • Not sure if persistent shedders, post-recovery, are infectious. The detection of viral RNA does not necessarily mean that the viral particles are viable. This issue has been discussed a lot online amongst virologists. But to be safe the Chinese quarantine recovered COVID-19 patients for 14 days at home to prevent delayed transmissions.
