ABSTRACT
The emergence of the coronavirus disease 2019 (COVID-19) caused a large-scale outbreak and has rapidly spread across China and multiple countries. We reported countermeasures in infection control for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) infection and the experiences of point of care diagnostics and medical quarantine for presumed SARS-CoV-2-infected subjects. We conducted a retrospective cohort study on subjects came to Chung Shan Medical University Hospital with suspicion of SARS-CoV-2 infection during January to March, 2020. We performed the real-time reverse-transcription polymerase chain reaction testing (rRT-PCR) for SARS-CoV-2-infection and reported the results of testing and treatment. A total of 212 participants were enrolled due to suspicion of SARS-CoV-2 infection. Five of those were confirmed COVID-19 cases after monitoring for a period of 14 days and were cured. The time to rRT-PCR test conversion after treatment is variate. The infection control measures of home quarantine and mandatory medical quarantine combined with rapid diagnosis seem to postpone the speed of transmission of SARS-CoV-2 infection at once in Taiwan. Due to lack of vaccination and confirmed antiviral therapy, it is important to strictly abide by the infection control measures.
