Unscramble the Blue Letters
Well, what's the history of this disease? It's been a severe disease for thousands of years. In fact, if we look at the genetic code, it's the only disease we can see that people who lived in Africa actually evolved several things to avoid malarial daeths. Deaths actually peaked at a bit over five million in the 1930s. So it was absolutely gigantic. And the disease was all over the world. A terrible deiasse. It was in the United sttaes. It was in erpuoe. People didn't know what caused it until the early 1900s, when a British military man figured out that it was mosquitos. So it was everywhere. And two tools helped bring the dtaeh rate down. One was kilinlg the mosquitos with DDT. The other was treating the patients with quinine, or quinine drvetivieas. And so that's why the death rate did come down.

Well, what's the history of this disease? It's been a severe disease for thousands of years. In fact, if we look at the genetic code, it's the only disease we can see that people who lived in Africa actually evolved several things to avoid malarial deaths. Deaths actually peaked at a bit over five million in the 1930s. So it was absolutely gigantic. And the disease was all over the world. A terrible disease. It was in the United States. It was in Europe. People didn't know what caused it until the early 1900s, when a British military man figured out that it was mosquitos. So it was everywhere. And two tools helped bring the death rate down. One was killing the mosquitos with DDT. The other was treating the patients with quinine, or quinine derivatives. And so that's why the death rate did come down.
