From: Treating cofactors can reverse the expansion of a primary disease epidemic
two-patch and four-patch cofactor: | |
---|---|
μ | disease-free death rate |
α | disease-related death rate |
ν | per capita birth rate |
β | disease acquisition contact rate |
ϵ | disease-free fraction of offspring from infected mothers |
four-patch cofactor only: | |
ζ | cofactor acquisition contact rate |
γ | cofactor recovery rate |
δ 1 | cofactor induced increase in susceptibility |
δ 2 | cofactor induced increase in transmission (eg. via increased pathogen concentration) |
λ 1 | rate adjustment for cofactor acquisition only from SZ contact |
λ 2 | 1 - λ 1 |
