SARS-CoV-2 Clinical Characteristics and Viral Shedding in Kuwait
OBJECTIVES: We aimed to describe the clinical characteristics of SARS-CoV-2 infection and estimate viral shedding duration in respiratory specimens. METHODS: A retrospective cohort study was performed from February 25 to March 25, 2020. In Kuwait, all suspected coronavirus disease 2019 (COVID-19) ca...

Sumario: | OBJECTIVES: We aimed to describe the clinical characteristics of SARS-CoV-2 infection and estimate viral shedding duration in respiratory specimens. METHODS: A retrospective cohort study was performed from February 25 to March 25, 2020. In Kuwait, all suspected coronavirus disease 2019 (COVID-19) cases, contacts of cases, and returning travelers were systematically tested for SARS-CoV-2 by RT-PCR. All infected persons, regardless of symptoms, were hospitalized and serially tested until they had two negative results. Descriptive statistics and regression analyses were performed. RESULTS: Two hundred seven cases of SARS-CoV-2 infection were included in this study. About half of the cases were asymptomatic and 1.9% died. The median time to negative RT-PCR was 22 days. Increasing age, ARDS, and low peripheral white blood cell count were associated with prolonged PCR positivity. CONCLUSION: Predictors for prolonged RT-PCR positivity included increasing age, ARDS, and low white blood cell count. The findings of this study may aid in better understanding of the epidemiology of SARS-CoV-2 infection and molecular testing dynamics. |
