We know this, it isn't rocket science.
If you truly want to wipe out an infectious disease in a given population of human beings, it only takes four steps. Billions of dollars worth of effort, but only four steps.
1. Create a cheap test that shows positive or negative for the infectious agent, and test *everybody*.
2. Those who test positive, physically separate into a quarantined area.
3. Hire researchers and caretakers to care for and treat the quarantined.
4. Use the quarantined population as a test bed to work on cures.
If you are working for the eradication of an infectious illness, and are not doing these four steps, you simply aren't trying very hard.
