SARS-CoV-2 Clinical Characteristics and Viral Shedding in Kuwait
Mohammad Alghounaim, Chelsea Caya, Khalid Alothman, Almonther Alhasawi, Jesse Papenburg
Abstract
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 Feb 25th to March 25th, 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: 207 cases of SARS-CoV-2 infection were identified. About half of 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 SARS-CoV-2 infection epidemiology and molecular testing dynamics.
