Credit for this claimed shift to a mathematical approach is given to the British physician and amateur mathematician, Sir Ronald Ross, who won the Nobel Award in 1902 for demonstrating how malaria spreads through mosquitoes. Ross carried out his mosquito researches while serving in British India. But epidemiology has always been mathematical, studying the population-wide spread of disease in a numerical and statistical way.
