The Philippines 2004 measles campaign: a success story towards elimination.

Prior to the 2004 Philippines Measles Follow up Elimination Campaign, measles caused an estimated 6000 deaths among Filipino children. After the campaign, cases and deaths decreased by 96.4% and 99.2%, respectively. The Nationwide Rapid Coverage Assessments, with an extensive system of feedback, was the prime factor in reaching the under-immunized areas.
