The Dangerous Gnat

We used to call them gnats in Lincoln. The Spanish call them mosquitoes (diminutive for mosca – fly). It was many years before I realised these are the same thing, basically, although there are different sorts.

For us they were just pesky nuisances, but this is mankind’s ‘deadliest predator’. How come? The answer: malaria. In 2018 there were 228,000,000 new cases and 400,000 died, but few in the ‘developed world’.

For millennia people got the ague, got sick and many died. It even decided major events, such as Hannibal’s failed assault on Rome, the limits of Alexander the Great’s conquering. It was thought to be bad air that caused it (mal-aria).

Eventually mankind found the cure – draining swamps and quinine, a refined variant of which, hydroxychloroquine, has been in the news recently. Of course, a lot of the world can’t afford these solutions.

This reminded me of a trip we took a few years ago to the unspoilt Aransas National Wildlife Refuge on the Texas coast. We stopped outside the gate of the reserve to take a quick entry photo, and by the time we got back in the car I had a number of mosquito bites on my arm. Of course, the whole of this eastern part of Texas was one big swamp before white men arrived. What a lot of mosquitoes! And what a heroic effort to carve the city of Houston out of such terrain. No wonder they use a lot of pesticide.

To know history and its causes is to understand today!

Thanks to an excellent review by Steven Shapin in the recent London Review of Books, on the book The Mosquito; A Human History of our Deadliest Predator by Timothy Winegard. Sounds like a great book!
