A COVID-19 confirmed case is a patient with an acute respiratory illness and RT-PCR confirmation of SARS-CoV-2 infection (i.e. any positive RT-PCR results obtained prior to admission or after enrolment in the study). In case the patient has any inconsistent RT-PCR results (e.g. a positive followed by a negative or a negative followed by a positive result), he/s he/she will be considered as a COVID-19 confirmed case if he/she has at least one positive result during his/her illness under consideration.
Other: no intervention
A COVID-19 negative case is a patient with an acute respiratory illness, in whom all RT-PCR tests are negative for SARS-CoV-2

Started Nov 2022 (actual). Primary completion is estimated for Nov 2023, 11 months after the start.
Of 1,640 non-industry observational studies under COVID-19, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 30. This study's planned 11 months is below that.
Counting every sponsor, half of 1,774 studies reached it within 13 months; a quarter within 5 and three quarters within 29.
