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.
On his return to India in 1895, Ross began his quest to prove the hypothesis of Alphonse Laveran and Manson that mosquitoes were connected with the propagation of malaria, and regularly corresponded with Manson on his findings.
