You cannot keep taking malaria medications in the long term. What I did is I took doxicyclin until I got a car, knew where was the hospital and knew some neighbours. If you treat Malaria quickly you shouldn't have much health issue so you need to make sure you can do that quickly.
There can be many mosquitos if you live in the land, but by the sea you don't see many of them. And houses are well equipped with mosquito nets.
