HIV epidemic evolves in three phases. First phase is low prevalence, when prevalence of the disease is less than 5% in any high risk group of the country. Second phase is concentrated epidemic when proportion of infected people in any high risk group rises more than 5%. Third and last phase of epidemic is generalized epidemic when prevalence of HIV infection rises over 1% among blood donor or pregnant women.
