How Does Environmental Variability Affect Disease Distribution?

Environmental variability can significantly affect the distribution and occurrence of diseases. For example, changes in temperature and humidity can influence the prevalence of vector-borne diseases such as malaria and dengue fever. Warmer temperatures may increase the breeding rates of mosquitoes, leading to higher transmission rates. Similarly, water quality and sanitation practices are closely linked to waterborne diseases like cholera and typhoid fever. Variability in these environmental conditions can lead to outbreaks or reductions in disease cases.
