* Chad’s human case count for January–December 2022 includes a human case detected in an area of the Central African Republic near the border with Chad.
† Civil unrest and insecurity since a coup in 2012 continued to constrain Guinea Worm Eradication Program operations (i.e., supervision, surveillance, and interventions) in Gao, Kidal, Mopti, Segou, and Timbuktu regions.
§ One human case and multiple infected animals detected in areas of Cameroon near the border with Chad might have been infected in Chad.
¶ Chad: primarily dogs, some cats; Ethiopia: dogs, cats, and baboons; Mali: dogs and cats; Angola: dogs; Cameroon: dogs and cats.
