I will highlight two or three things that are very important.
One is the focus on health system strengthening, meaning that we are not only working towards the three specific diseases, but we know from experience that we need to build health systems in order to end the epidemics. Therefore, the systems are supposed to be sustainable to deliver other health outcomes and development outcomes for the country.
Health system strengthening is key to the sustainability of our efforts. We are investing about a fourth of our current investment in that area—about $1 billion U.S. a year, which is very significant.
The second element towards sustainability and towards ensuring that there is a future is the fact that we are catalyzing domestic resources for help through our co-funding requirements. This means that each time we allocate a grant to a county to fight the three diseases, we also require them to step up their own efforts, and their own funding for the fight against these three diseases and for building their own health systems. We've been very successful in doing that.
In the current investment case, we are projecting an increase of 48% of domestic resources for health. We expect implementing countries to actually invest most of the resources that are needed to step up the fight and end the epidemics by 2030. If we are requesting at least $14 billion for the Global Fund, we are in fact expecting the implementing countries to invest $46 billion, which is much more.
This is increasing and making our efforts sustainable through this catalytic effect. As a testimony of that, we also have a sustainability and transition policy. Some countries transit through multi-year plans towards picking up the responsibility of taking care of the fight against these three diseases by themselves. This is a testimony of how countries become responsible and pick that up.
