Status for the period January–February 2016
As of February 2016, a cumulative total of 1 case has been reported from Sarh (quartier Kassai) village, Sarh District, Moyen Chari Region. The case was contained.
From January to March 2016, of the 218 dogs reported with Dracunculus medinensis infection, 166 (76%) 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 being undertaken to find appropriate ways to interrupt transmission of infections in both humans and animals.
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.
