A total of 1011 dogs were reported with D. medinensis infection, of which 665 (66%) were contained.
Since 2012, an unusually large number of dogs infected with the parasite has been reported along the Chari River in the same areas where human cases are being reported.
The parasites found in dogs are genetically indistinguishable from those emerging from humans. Operational research is under way to find appropriate ways to interrupt transmission of infections in both humans and animals.
A total of 3093 rumours were reported, of which 97% were investigated within 24 hours.
