Measles Quote by David Quammen
““It comes and it goes. But epidemiologists have recognized that, with measles virus, as with other pathogens, there’s a critical minimum size of the host population, below which it can’t persist indefinitely as an endemic, circulating infection. This is known as the critical community size (CCS), an important parameter in disease dynamics.””
About This Quote
Source Book: Spillover by David Quammen, 2012
A disease needs a sufficiently large host population to continue spreading; below a certain threshold it dies out.
In simple terms: Pathogens need enough hosts to survive.
