seircovid2S

sircovid2S is an R package for running a compartmental model which captures the history of infection with 2 strains of SARS-CoV-2 in an age-structured population.

knitr::include_graphics("model_schematic.png")

We consider the case of 2 strains of SARS-CoV-2 in circulation (1 and 2). Infection with any of the two strains is assumed to confer life-long immunity. The age-stratified population is assumed to have constant size and to be structured into:

• $S$ = susceptibles
• $I_1$ = infected with strain 1
• $I_2$ = infected with strain 2
• $R_1$ = recovered from infection with strain 1
• $R_2$ = recovered from infection with strain 2
• $I_12$ = currently infected with strain 2, having previously been infected with strain 1
• $I_21$ = currently infected with strain 1, having previously been infected with strain 2
• $R_12$ = recovered from infections with both strains
