Figure 9From: A unified framework of immunological and epidemiological dynamics for the spread of viral infections in a simple network-based populationHaving people's immune systems primed through re-infection prevents infection from reaching the rest of the population. Having key core people's immune system primed against re-infection (A and B) causes them to serve as barriers that prevent an outbreak from reaching the rest of the population, as measured by the accumulated viral load (C).Back to article page
