who discovered malaria

Malaria was first discovered to be caused by a protozoan parasite by the French physician Charles Louis Alphonse Laveran in 1880.

Core discovery

Laveran observed parasites inside the red blood cells of a patient with malaria on November 6, 1880, at the military hospital in Constantine, Algeria, identifying them as the causative agent of the disease.

This was the first time a protozoan was recognized as the cause of a human disease, and Laveran later received the Nobel Prize in Physiology or Medicine in 1907 for this work.

Role of mosquitoes

Later, in 1897, British doctor Sir Ronald Ross showed that malaria parasites are transmitted by mosquitoes by finding the parasite in the gut of a mosquito that had fed on an infected host.

Ross’s work proved the mosquito transmission cycle and earned him the Nobel Prize in Physiology or Medicine in 1902.
