A member of the Cuban army fumigates against the Aedes aegypti mosquito to prevent the spread of zika, chikungunya and dengue, in Havana, on February 23, 2016. Cuban President Raul Castro announced Monday that 9,200 troops and police have been mobilized in a campaign to eliminate mosquitoes and protect the country against the Zika virus. Cuba has not officially recorded any cases of the mosquito-borne virus, which is strongly suspected of causing serious birth defects in babies born to infected mothers. But 28 countries and territories in the Americas and the Caribbean have reported cases of active Zika transmission, with 1.5 million in Brazil, the hardest-hit country. AFP PHOTO / YAMIL LAGE
