In the 1940s and 1950s, Brazilian authorities made such a ferocious assault on Aedes aegypti – the mosquito that spreads the Zika virus – that it was eradicated from Latin America’s largest country by 1958.
But Aedes aegypti returned, and now Brazil has launched another offensive against the pest, employing hundreds of thousands of troops to fumigate and educate people about how to eliminate its habitats. The assault is part of President Dilma Rousseff’s “war” on the Zika virus, which the Centers for Disease Control and Prevention says can cause devastating birth defects.
But eradication experts say there is little chance Brazil can come anywhere near stamping out the pest like it did a half century ago. The world is different, with globalization bringing more travelers and trade across borders. And Brazil is different; its resources are limited as the country suffers through its worst recession in decades and its president is focused on battling impeachment for allegedly breaking fiscal rules in managing government funds.
