What year did malaria start?
Malaria first emerged as an infection of humans tens of thousands, if not hundreds of thousands, of years ago. The species of malaria that infect humans probably evolved from closely related malaria species that infect macaques (in the case of Plasmodium vivax) and gorillas (in the case of P. falciparum).
The earliest records from human history of malaria come from a Chinese medical parchment almost 5000 years ago, and it is believed the ancient Egyptians also recognised the symptoms of the disease. Written accounts of malaria also occur in ancient Roman and Greek texts, though the true causes of malaria were not discovered until the 19th century.
