“I lit a thin green candle to make you jealous of me, but the room just filled up with mosquitoes”*…




It turns out that, if you’re looking for them, the words “mosquitoes,” “fever,” “ague,” and “death” are repeated to the point of nausea throughout human history. (And before: … when the asteroid hit, dinosaurs were already in decline from mosquito-borne diseases.) Malaria laid waste to prehistoric Africa to such a degree that people evolved sickle-shaped red blood cells to survive it. The disease killed the ancient Greeks and Romans—as well as the peoples who tried to conquer them—by the hundreds of thousands, playing a major role in the outcomes of their wars. Hippocrates associated malaria’s late-summer surge with the Dog Star, calling the sickly time the “dog days of summer.” In 94 B.C., the Chinese historian Sima Qian wrote, “In the area south of the Yangtze the land is low and the climate humid; adult males die young.” In the third century, malaria epidemics helped drive people to a small, much persecuted faith that emphasized healing and care of the sick, propelling Christianity into a world-altering religion…

In total… mosquitoes have killed more people than any other single cause—fifty-two billion of us, nearly half of all humans who have ever lived. [They are] “our apex predator,” “the destroyer of worlds,” and “the ultimate agent of historical change.”…

They slaughtered our ancestors and derailed our history– and they’re not finished with us yet: “How Mosquitoes Changed Everything.”

* Leonard Cohen


As we nestle under our nets, we might spare a thought for Girolamo Fracastoro; he died on this date in 1553.  A physician, poet, and scholar of mathematics, geography, and astronomy, he he proposed (in 1546) that epidemic diseases are caused by transferable tiny particles or “spores” that could transmit infection by direct or indirect contact or even without contact over long distances; he called these infectious agents fomes, from the Latin, meaning tinder.  His theory was influential for three centuries, until it was sufficiently refined and extended to become modern germ theory, which superseded Fracastoro’s model.
