Clinical outcomes of initially asymptomatic patients with COVID-19: a Korean nationwide cohort study.

ABSTRACT:

Background

This study was performed to compare severe clinical outcome between initially asymptomatic and symptomatic infections and to identify risk factors associated with high patient mortality among initially asymptomatic patients.

Methods

In this retrospective, nationwide cohort study, we included 5621 patients who had been discharged from isolation or died from COVID-19 by 30 April 2020. The mortality rate and admission rate to intensive care unit (ICU) were compared between initially asymptomatic and symptomatic patients. We established a prediction model for patient mortality through risk factor analysis among initially asymptomatic patients.

Results

The prevalence of initially asymptomatic patients upon admission was 25.8%. The mortality rates were not differ
