Regarding chloroquine / hydroxychloroquine, it is very unlikely that those drugs are still in widespread usage in Africa. While for many years the drug of choice for fighting malaria, it long ago lost its effectiveness. Even by the early 1990s, the malaria parasite had developed an immunity to chloroquine, and I well remember the headlong rush there then was to develop alternatives (which luckily was successful).
There is currently quite a cocktail of anti-malarial medicines available in malaria-affected countries. However, neither chloroquine nor its more soluble version, hydroxychloroquine, feature amongst these!
