Onchocerciasis status

Onchocerciasis is a country-wide public health problem in Nigeria.

Rapid epidemiological mapping of onchocerciasis in Nigeria, showing areas (in red) where community-directed treatment with ivermectin is needed

This map is an approximation of actual country borders.

Ivermectin coverage

Geographical coverage (2007)
  • Number of communities treated with ivermectin: 33 924
  • Treatment target (number of communities): 35 339
  • Geographic coverage (2006): 96%
Therapeutic coverage (2007)

Co-implementation of CDTI and other health interventions

In addition to delivering ivermectin, community-directed distributors (CDDs) are being trained to deliver other health care interventions to their community.

Number of CDTI projects with distributors delivering other health interventions (2007):

  • Malaria
  • Bednet
  • Lymphatic flariasis
  • Vitamine A
  • Schitosomiasis
  • Guinea Worm
  • Primary Eye Care
