This is from a page from the Australian Gov web site on the Internet:-
The A$2.9-million Roll Back Malaria in Mindanao initiative, implemented from 2004 to 2007 in partnership with World Health Organization, aims to reduce malaria transmission, morbidity and mortality in high incidence provinces of Mindanao by 50 percent.
Other pages show its not a problem except in the rural areas.
For those who wanna know, I suggest a search 'Malaria in Mindanao' would be useful.
