The Municipalidad de Palmares said Thursday that 28 cases of suspected dengue have been reported there so far this year.
Municipal officials have issued a call for citizens to take preventative measures. They also noted that the chinkungunya virus is carried by the same mosquito, and that there is a danger that this illness will appear.
The municipality said it is joining with the Ministerio de Salud seeking citizens to eliminate the places where mosquitoes may develop.
The rainy season usually increases the number of places where the Aedes aegypti mosquitoes may lay eggs.
