Figure 1From: Effects of an ageing population and the replacement of immune birth cohorts on the burden of hepatitis A in the Netherlands Compartmental model for the transmission of hepatitis A, shown for the age group <1 years (for all other age-groups, the inflows to the M and S compartments due to births are not present). The model is stratified by sex and and by age (1-year age groups, from <1 years to 85+ years), with ageing simulated by advancing all compartments one age group at the end of each simulation year.Back to article page
