Definitions

Endemic country: A country with any designated administrative areas [implementation units (IUs)] known or reported to be endemic since 1980.

At-risk population: Total population in endemic administrative areas [implementation units (IUs)].

At-risk population living in areas with MDA: Total population in endemic areas where mass drug co-administration (MDA) is being implemented.

At-risk population covered by drug co-administration: Number of individuals reported to have ingested anti-filarial drugs in the adequate dosage. This number will never equal the population living in areas with MDA because pregnant women, children under two years of age (DEC plus albendazole combination) and children under 90 cm in height (ivermectin plus albendazole), and the very sick are not given drugs.

Percentage of at-risk population living in areas with MDA: (The total population in areas with mass drug co-administration divided by the total population of all endemic areas) x 100. Also known as geographic coverage.
