Strap in, folks. The whole article is like this
The parasite enters your body via a deer fly bite. Luckily for the whole world except Western and Central Africa, the parasite only lives in Western and Central Africa. Loa Loa is currently inside millions of Africans. The good news is that there's medicine that clears it right up. The bad news is that said medicine can f**king kill you. That's because the parts of Africa which Loa Loa plagues harbor more than one horrific parasite. They also have to deal with Onchocerca, a ringworm which causes "river blindness." A lot of people have both parasites at one time. If a person takes medicine to kill one while they have the other as well, they can go into a coma or straight up die, for reasons science doesn't understand.
Oh, and American deer flies are theoretically suitable hosts for Loa Loa, meaning it's technically possible for it to spread to the United States. Maybe you should start lighting things on fire now to be prepared.
