Abstract
We studied 2351 participants with coronavirus disease 2019; 1177 (50%) reported previous dengue infection. Those without previous dengue had a higher risk of death (hazard ratio: .44; 95% confidence interval: .22-.89; P = .023) in 60-day follow-up. These findings raise the possibility that dengue might induce immunological protection against severe acute respiratory syndrome coronavirus 2.
