Comparison of the Efficacy of Rapid Tests to Identify COVID-19 Infection (CATCh COVID-19)
Comparison of the Efficacy of Rapid Tests to Identify COVID-19 Infection (CATCh COVID-19)
This study is designed to compare the efficacy of detection of COVID-19 infection using the
 serology test in blood sample and the PCR-based test in the nasopharyngeal (NP) and sputum
 sample. Furthermore, it aims to evaluate the temporal trend of appearance of IgM and IgG in
 blood.
The investigators hypothesize that viral-RNA test using sputum will be equally efficient as
 the test performed in NP swab. Moreover, the serology test and the PCR-based test will be
 comparable in efficacy for detection of infection
