With regards to the use of Malarone, while you can get it, it is not yet recommended for areas where the malaria is not yet resistant to Chloraquine.
Ergo, Malarone is the bigger gun that will be brought out when Chloraquine is no longer effective. And an added benefit, at this time Chloraquine is also significantly less expensive than Malarone.
