25. Dengue fever incidence: Trinidad and Tobago

There is neither good prophylactic nor cure for dengue fever, a disease spread by Aedes aegypti mosquitoes. There are four different strains of the disease. Infection by one of the strains does not provide immunity against the other strains. The symptoms range from a non-specific viral syndrome to fatal hemorrhagic disease. Increasing temperatures promote the spread of this disease.
