Epidemiology

The branch of medical science that deals with the frequency and spread of viruses in populations over time is called Epidemiology. It is used to disrupt the series of infection in populations during outbursts of viral diseases. Host, virus and environmental factors are watched to define the dynamics of viral infections, the final goal is to devise intervention strategies. Programme of viruses can be vertical, means from mother to child (or) horizontal, means from person to person. The rate of transmission of viral infections depends on factors that include population density, the number of susceptible individuals, the worth of healthcare and the weather.
