It is suspected that the high incidence of dengue fever helps confer protection against yellow fever, and that the Asian mosquito strains are not as competent as vectors of the disease.
- Previous exposure to or infection with dengue appears to confer some protection against yellow fever.
- Treatment consists of complete bed rest--including sedatives if necessary; a high-protein, high-carbohydrates liquid diet; analgesics for headache; and antipyretics and tepid sponge baths to reduce fever.
- Fluids must be carefully monitored for adequate blood volume; transfusions may be required.
- In severe cases, patients may receive calcium gluconate to help counteract hemorrhaging.
