In this modern world, HIV remains a fact of life. There are some Zoe working-group members that are HIV positive. I understand that the treatment to keep it in check is covered by the national health insurance of several African countries in which Zoe operates, but there are still challenges. The primary one is social stigma, but there’s also the difficulty, sometimes, of getting transport to whatever clinic is administering the treatment. (Those two things might be related, since you might not want to just pop down to your local village pharmacy to pick up a bottle of pills that can only have one use.)

Zoe ensures that each group member is tested and they get what they need to stabilize themselves, and it’s all handled discretely.
