Congenital and Blood Transfusion Transmission of Chagas Disease: A Framework Using Mathematical Modeling

Figure 1

Flow chart for the dynamics of proposed model. Letters inside box indicate the number of individuals in each compartment: infected women from country with vector (), healthy women from country with active vector transmission (), infected men from country with active vector transmission (), healthy men from country with active vector transmission (), infected women from country without vector transmission (), healthy women from country without vector transmission (), infected men from country without vector transmission(), and healthy men from country without vector transmission (). is the death rate for healthy people and is the death rate for infected people. is the rate of infection due to blood transfusion. Dashed lines indicate the births. Newborns from can be an infected female (1), healthy female (2), healthy male (3), or infected male (4). The same occur for newborns from that can be infected female (5), healthy female (6), infected male (7), or healthy male (8). Healthy women and only gave birth to healthy newborns (flows not shown).
