Critical community size
Critical community size (CCS) is the minimum size of a closed population within which a human-to-human, non-zoonotic pathogen can persist indefinitely. When the size of the closed population falls below the CCS level, the low density of infected hosts causes extinction of the pathogen. This epidemiologic phenomenon was first identified during measles outbreaks in the 1950s.
