||Taiwan (traveller from Wuhan)
A 50 year old woman continued to shed live virus until day 18 and non viable virus until day 63 from symptom onset.
The study is a letter to the editor reporting the case of a 50 year old woman traveller from Wuhan to Taipei who became symptomatic after 2 days, excreted live virus in sputum for 18 subsequent days and non viable viruses until day 63.
Serial RT-PCR results in this case highlight the importance of the clinical specimens sampled from lower respiratory tract for detecting SARS-CoV-2 virus.
What did they do?
The study is case report undated.
A single case report requires replication.
|Clearly defined setting
||Demographic characteristics described
||Follow-up length was sufficient
||Transmission outcomes assessed
||Main biases are taken into consideration
What else should I consider?
This case report requires replication. Although culture was performed viral load (ct) was not quantified.
