OverviewEdit

Mycobacterium tuberculosis

The Disease Rate determines how prevalent disease is in a city's population and, as a result, how many people are killed by disease. It is lowered by decreasing  the population density of the city or by purchasing improvements like Hospitals (the decrease Disease directly) and Subways and Recycle Centers (that decrease Pollution and, as a result, Disease too, indirectly). It is increased by purchasing certain improvements that increase Pollution and by buying more infrastructure (increases Base Population and Population Density).

The Disease Rate cannot be lower than 0% and cannot be higher than 100% (known as Atzuya's limit). At 100%, a city will be losing population equal to 100 times it's Infrastructure (the formula for Base Population) and will therefore be left with the minimum population of 10.

ImportanceEdit

A positive Disease Rate will decrease the population of a city, which in turn decreases the income from a city's population.

Population Reduction Edit

The formula that determines how much population is reduced by in a city is a function of the Disease Rate and Infrastructure.

People Killed by Disease = Disease Rate * Infrastructure * 100
