Allergic Disorders and Susceptibility to and Severity of COVID-19: A Nationwide Cohort Study

Category:

Topic:

  • In a propensity-score-matched nationwide cohort study (n=219,959) of individuals tested for SARS-CoV-2 in South Korea, patients with allergic rhinitis and asthma were more likely to have a positive SARS-CoV-2 test and to have severe COVID-19 outcomes if infected, compared to individuals without these conditions. The greatest increased risk was among those with non-allergic asthma (for positivity, aOR=1.3, 95%CI 1.1–1.7; for severe disease, aOR=4.1, 95%CI 1.7–10.5).
