As of 30 September 2016, 944 of the dogs were reported with Dracunculus medinensis infection, of which only 631 (67%) were contained.

Since 2012, an unusually large number of dogs infected with the parasite have been reported along the Chari River in the same areas where human cases are being reported. The parasites found in dogs are indistinguishable by polymerase chain reaction (PCR) analysis from those emerging from humans.

Operational research is under way to find appropriate ways to interrupt transmission of infections in both humans and animals.

As of 30 September 2016, 1562 rumours of dracunculiasis have been reported; 98% were investigated within 24 hours.

Since 2009, a nationwide cash reward of CFA 50 000 [about US$ 100] has been offered for the voluntary reporting of dracunculiasis cases. People are requested to report to the nearest health facility.
