K-K, Kato-Katz test;

^£Areas are classified according WHO; pSC, pre-school children; SC, School Children; GP, General Population.

^*Prevalence calculated based on the total results obtained by the examination of two slides/stool sample/person;

^**Sensitivity was determined on the results from the examination of at least one stool sample/person (2 slides/sample of stool).
