Quinine hasn’t been used for malaria prophylaxis since the times of the British Empire. Even for its successor, Wikipedia has this:
> Areas of the world with chloroquine sensitive malaria are uncommon.[84]
The overlap between countries with few cases of Coronavirus and those with Malaria is tenuous at best. Turkey doesn’t have Malaria, and for that matter neither does Russia.
People in Malaria areas also tend not to use pharmacological prophylaxis, because the side-effects are impossible to tolerate in the long term. Prophylaxis is for tourists. That’s why mosquito nets are such effective intervention.
