QUESTION:

Who found that malaria was caused by a mosquito?

ANSWER:

The man who first discovered that malaria was transmitted by mosquitoes was a British Army doctor called Ronald Ross. Working in India in 1897-1898, Ross demonstrated how malaria parasites could be transmitted first between a patient and a mosquito, and then between hosts via mosquitoes (this latter work was done using birds). Ronald Ross was honoured with the Nobel Prize in 1902 for his discoveries.
