Experience in global measles control, 1990-2001.

Worldwide during the 1980s remarkable progress was made in controlling measles through increasing routine measles vaccination to nearly 80%. In 2000, an estimated 777,000 measles deaths occurred, of which 452,000 were in the African Region of the World Health Organization (WHO). In 2001, WHO and the United Nations Children's Fund published a 5-year strategic plan to reduce measles mortality by half by 2005. Strategies include providing a second opportunity for measles immunization to all children through nationwide supplementary immunization activities, increasing routine vaccination coverage, and improving surveillance with laboratory confirmation of suspected measles cases. In 2000, over 100 million children received a dose of measles vaccine through supplementary immunization activities, a number projected to increase during 2002-2005. Current systems for monitoring measles vaccination coverage and disease burden must be improved to accurately assess progress toward measles control goals.
