The Health Protection Agency (HPA) has issued an alert warning of the spread of dengue and viral fever in Malé and the atolls.
The HPA said its statistics show an increase in the incidence of mosquito-borne dengue fever and advised precautionary measures to control mosquito breeding during the rainy season.
The agency also advised ensuring cleanliness and seeking medical assistance if a fever persists for more than three days.
Last year, the health ministry said dengue fever has become endemic in the Maldives since 2004 with annual outbreaks.
