Epidemiology studies the distribution and determinants of health-related states in populations, and poliovirus is a classic example of a disease that has been targeted for eradication through vaccination campaigns. The virus has three serotypes: PV1, PV2, and PV3, with PV1 being the most commonly encountered. Understanding the epidemiology of poliovirus involves assessing factors like the host susceptibility, environmental conditions, and the effectiveness of interventions.
