Impact of immigration on HCV disease burden

In our modeling of Hepatitis C Virus, we look at individual countries and regions to predict their current disease burden. To create a more detailed picture of country specific burden, we have developed a module that looks at the number of people migrating each year to that country. By using the number of immigrants per year and the corresponding age, we are able to account for the number of new HCV infections entering a country through immigration and allocate them to the corresponding disease stage. The module assumes that the prevalence by age (and disease stage by age) among immigrants is the same as the rest of the population in the country of origin. This kind of data helps to provide a more accurate estimation of HCV prevalence and informs more effective policy making towards screening and treatment of HCV patients.
