5por Artzy-Randrup, Yael, Rorick, Mary M, Day, Karen, Chen, Donald, Dobson, Andrew P, Pascual, Mercedes“…The model explicitly considers the extensive diversity of multi-copy genes that undergo antigenic variation via sequential, mutually exclusive expression. It tracks the dynamics of all unique var repertoires in a population of hosts, and shows that even under high levels of sexual recombination, strain competition mediated through cross-immunity structures the parasite population into a subset of coexisting dominant repertoires of var genes whose degree of antigenic overlap depends on transmission intensity. …”

The vast diversity of “strains” and genes encoding this variation challenges the application of established models for the population dynamics of such infectious diseases. …”

9“…Influenza A (H3N2) offers a well-studied, yet not fully understood, disease in terms of the interactions between pathogen population dynamics, epidemiology and genetics. A major open question is why the virus population is globally dominated by a single and very recently diverged (2–8 years) lineage. …”

Re-emergence times are shown to be highly sensitive to small changes in low R(0) (secondary cases produced from a primary infection in a fully susceptible population). …”
