Serological co-infection of dengue and COVID-19: case series in Bangladesh

Parallel symptoms and laboratory findings between dengue and coronavirus disease 2019 (COVID-19) pretense a diagnostic contest in some dengue-endemic countries in Asia. In this study, we described ten cases of suspected COVID-19-dengue co-infection in a tertiary care hospital in Bangladesh. Serological data showed that patients with positive results for dengue virus (DENV) NS1 antigen and anti-dengue IgG and IgM were also reactive to COVID-19 rapid antibody tests, suggesting dengue with COVID-19 coinfection. The present study indicated a public health concern regarding COVID-19 and dengue detection in Bangladesh as well as in other dengue-endemic countries and it was important for these nations to manage both pathogens concurrently.
