“A distinction should be made between formal policy (which is currently sequential deployment virtually everywhere) and the pragmatic realities of different countries and regions. Distribution of designated ACT through the formal health sector is the official policy in most countries.”
There is a whole body of literature attempting to find the best method of prophylaxis for the whole population.

The literature examines whether rotating the anti malarials used will hinder development of resistance.
