Eduardo Hernandez (R), 52, a member of a fumigation brigade leaves a house after inspects in Havana February 2, 2016. Cuba conducts regular fumigation inside homes to check the spread of dengue, a virus transmitted by the Aedes aegypti mosquito that causes a fever which can be deadly. The same mosquito can also spread the Zika virus, although the Cuban government says there have been no reported cases of the disease in the country.
