Who discovered the disease malaria? Who discovered the malaria disease and when? Malaria has been known for thousands of years; there are written accounts of the disease, including a description of its symptoms, in ancient Chinese medical texts from 2700 BCE. The ancient Romans and Greeks also knew about malaria. However, the causes of the disease were only discovered in the 19th century. In 1880, a French surgeon called Charles Louis Alphonse Laveran stationed in Algeria was the first person to see the parasites that cause malaria in the blood of an infected person.
Regardless of exactly how it was discovered, the first documentation of its use as malaria is recorded in 1630 in Peru. It continued to be used for its antimalarial properties until the 1920s, when other drugs with fewer side effects took its place, like chloroquine. That's almost 300 years of use.
