Islamic Africa is AIDS free while Christian Africa has it en masse. Islam will prevail always
While this is true but there is something you need to consider.
Muslims are not open to fornication like non-Muslims who proudly brag about it. They only keep it to themselves for extremely obvious reasons so they’re less likely to get tested and ignore the symptoms.
I remembered reading various Muslim majority ethnic forums back then (before social media killed it), many Muslim forumers shared stories of hearing how one got sick and discovering their partners had those diseases and strongly advocated testing in their countries before marriages because of it.
So, it is a widespread issue but we will never know the real statistics. Not to mention, the lack of resources etc.
