Affordable drugs are absolutely critical for all three diseases. The good news here is also that the prices for these drugs have come down dramatically. When the Global Fund was created 10 years ago, it was not only that we able to mobilize billions of dollars but also that the prices for drugs at that time were about $10,000 per patient per year. It was absolutely unaffordable with whatever kind of resources you would get.
Nowadays, we pay between $100 and $200 per patient per year for a complete treatment for AIDS, so that's a huge drop in the price. Similarly, the price of malaria drugs, the artemisinin-based combination therapy, has come down now to less than one dollar for the complete treatment that can cure malaria. For tuberculosis, the whole six-month drug treatment costs around $50.
These drugs have become much more affordable. This means that an upper-middle-income country like Botswana can now afford these themselves. But we need to continue to support lower-income countries like Democratic Republic of Congo, Ethiopia, Haiti, or many others. Otherwise, they would not be able to provide these drugs to their people.
