Are diseases more common in certain regions?
I was playing my Abbasid Caliphate game recently and saw a smallpox outbreak pop up in the south.
Normally this wouldn't be noteworthy but I stopped and realized that I hadn't seen one in many hours. In my Ireland game it seemed like I rarely went an hour without an outbreak, and in Norway one every two hours seemed normal even before I expanded beyond the borders of a single Kingdom. So that got me wondering, are disease outbreaks more common in some places than in others?

Why disease is more common in the certain area?
Some genetic disorders are more likely to occur among people who trace their ancestry to a particular geographic area. People in an ethnic group often share certain versions of their genes, which have been passed down from common ancestors.How does geography affect disease?
Infectious diseases vary by geographic region and population, and they change over time. Increasingly, humans are moving from one region to another, thereby becoming exposed to a variety of potential pathogens and also serving as part of the global dispersal process.Where do new diseases most commonly originate?
In fact, 75 percent of new or emerging diseases originate in animals, and more than 60 percent of known infectious diseases in people, such as the rabies virus, ringworm and salmonella, are transmitted from animals, according to the CDC.What regions in the world are most impacted by communicable diseases?
Sub-Saharan Africa will remain the region most affected by the global infectious disease phenomenon--accounting for nearly half of infectious disease-caused deaths worldwide. Deaths from HIV/AIDS, malaria, cholera, and several lesser known diseases exceed those in all other regions.Travel Medicine: Diseases with Regional Patterns
