Measles is primarily considered a propagated transmission epidemic. It spreads through respiratory droplets when an infected person coughs or sneezes, allowing the virus to propagate among susceptible individuals. While it can occur in localized outbreaks, it is not typically classified as a common source epidemic, which usually involves a single source of infection affecting a population simultaneously. Vaccination has significantly reduced the incidence of measles in many regions, but outbreaks can still occur, particularly in areas with low vaccination rates.
