So far over 4000 babies, the most susceptible, have been born with microcephaly and a few adults have died. Critics blame the Brazilian government for not better controlling the mosquito population.

The most efficient and potent mosquito control chemical ever invented is kept on the sidelines of the war on mosquito-borne disease because of a ridiculous, poorly done study by a flaky environmentalist Rachel Carson and then FDA head and Greenpeace officer Bill Ruckelshaus who banned it solely because of Carson's stupid book, "Silent Spring".
The smug sanctimony of American environmentalists has condemned millions of third-world peasants to death, disease, and birth defects.
