Previous Dengue Infection and Mortality in COVID-19

Category: Article Summary

Topic: Clinical Characteristics and Health Care Setting

Keywords (Tags): risk factors

In a prospective study of 2,351 people with COVID-19 SARS in Brazil, those with previous symptomatic dengue (n=1177) had a lower risk of death after a median follow-up of 60 days (adjusted HR = 0.44). History of other previous infections, including malaria, Zika, and chikungunya, were not associated with mortality. The authors suggest that dengue might induce a degree of immunological protection against SARS-CoV-2 infection.
