More than 200,000 army, navy and air force troops fanned out across Brazil on Saturday to teach people how to eliminate the Aedes aegypti mosquito that spreads the Zika virus that many health officials believe is linked to severe birth defects, AP reported. The nationwide offensive is part of President Dilma Rousseff's declared war on the virus that has quickly spread across the Americas. According to Brazil's government, about 220,000 members of the armed forces accompanied by community health agents and mosquito control teams were deployed Saturday to help educate the population on how to eliminate mosquito breeding areas in and around their homes. The teams were expected to visit 3 million homes in 350 cities to distribute explanatory pamphlets. Wearing a white T-shirt printed with the campaign's "Zero Zika" slogan, Rousseff visited Rio de Janeiro's working class neighborhood of Zeppelin. She was accompanied by Mayor Eduardo Paes and Rio de Janeiro state governor Luiz Fernando Pezao. The president visited three homes and chatted with residents about the importance of eliminating the breeding areas for the mosquito that also transmits dengue, chikungunya and yellow fever. In one house, she sprayed insecticide in drains that could serve as mosquito breeding areas. Rousseff said in brief comments to reporters that the Zika outbreak will not stop this year's Olympic Games from being held in Rio de Janeiro as scheduled, starting on Aug. 5.
