That's a fascinating question. The mix will differ from country to country. Essentially, prevention takes education, and awareness in particular, in highly vulnerable populations. This is where you need community leaders and you need peer-to-peer education. You don't need a formal doctor going into those populations. You need a particular approach, in that sense.
You also need tools. You need tests, tests, tests, and in that sense, you need self-tests, for example. We need to scale up self-testing. This is one of the lessons we learned from COVID as well. These tools are really important, as is all the treatment, obviously, including prep.. There is still a lot to be done in that space.
