Why is Genetic Variability Important in Epidemiology?
In epidemiology, genetic variability plays a pivotal role in numerous aspects. It helps in understanding the susceptibility of individuals to diseases, the variation in disease severity, and the response to treatments and vaccines. For instance, certain genetic markers may make individuals more susceptible to infectious diseases like HIV or malaria. Similarly, genetic variability can influence how different populations respond to environmental factors, such as toxins or pathogens.
