In Africa, the virus is carried by the Aedes africanus mosquito, which is classically found along the continent’s equatorial belt stretching from Cape Verde to Kenya. Few human beings ever acquired Zika because the africanus mosquitoes mostly fed on wild monkeys and chimpanzees.
David Morens and Anthony Fauci (who heads the U.S. National Institutes of Allergy and Infectious Diseases) argue that changes in lifestyle in Africa in the later twentieth century afforded the virus the opportunity to infect another, more globally common mosquito, Aedes aegypti.
As villagers built rainwater-catching devices and uncovered containers full of water became common across Africa, the aegypti mosquitoes placed their larvae in the fresh, clean still water. The aegyptipopulations swelled all over the continent, expanding into Aedes africanus territory and likely feeding on primates that had been infected with Zika by africanus.
In late 2015, the record-breaking El Niño was wreaking havoc across South America, forcing evacuation of more than 150,000 people in Paraguay due to torrential downpours and flooding and causing a drought in northern Brazil. Much of Brazil has been hit by heavy rains, however, causing significant agricultural losses and prompting President Dilma Rousseff to declare emergencies after Christmas in the country’s southernmost states. The rains left more puddles, pools, and ponds for mosquito breeding, allowing both Aedes species to surge across the region.
And all three
diseases—dengue, chikungunya and Zika—are now prevalent. In the first quarter of 2015, Brazil suffered 460,000 cases of dengue,120,000 more than in the same period of 2014. -
