Evidence of recent dengue exposure among malaria parasite-positive children in three urban centers in Ghana

Blood samples of 218 children ages 2-14 years old with confirmed malaria in hospitals across Ghana were tested for dengue virus exposure. We detected dengue-specific immunoglobulin M (IgM) antibodies in 3.2% of the children, indicating possible coinfection, and IgG antibodies in 21.6% of them, which suggests previous exposure. Correlates of exposure are discussed.
