Mapping diseases goes way back. In the infamous Broad Street pump incident of 1854, John Snow mapped cases of cholera in a London neighborhood during an epidemic and noticed most cases were using water from the same pump.

Maps easily show the distribution of diseases. This visualization of the distribution is useful for many applications in public health. For example, if you were planning a campaign to distribute mosquito nets in Africa to prevent malaria, a map would show you that malaria is not endemic in the Sahara desert as it is Sub-Saharan Africa. The map helps you prioritize net distribution to the highest risk areas. Such maps are relevant for all diseases across the field of public health.
