Previous Dengue Infection Increases COVID-19 RiskMay 19, 2021
Experts from the University of São Paulo analyzed blood samples from Brazil and found that people who have had Dengue previously are twice as likely to exhibit COVID-19 symptoms when infected by the SARS-CoV-2 virus. The study is published in the Oxford Academic journal Clinical Infectious Diseases.
The researchers collected blood samples from 1,285 residents of Mâncio Lima, a small town in the state of Acre, part of Brazil's Amazon region. The results showed that the populations most exposed to Dengue, probably due to socio-demographic factors, are at high risk of getting sick when infected by the SARS-CoV-2 virus. Marcelo Urbano Ferreira, leader of the study, said that the results indicate an example of a synergistic epidemic or syndemic, wherein two epidemic diseases exhibit a synergic interaction so that one aggravates the effects of the other.
