Dracunculiasis

Chad

Status for the period January–April 2016

As of 30 April 2016, a cumulative total of 2 cases were reported, one from Sarh (quartier Kassai) village, Sarh District, Moyen Chari Region and one from Ngara village, Bailli district, Chari Baguirmi region. The cases were contained. Both cases were male children.

From January to April 2016, of the 337 dogs reported with Dracunculus medinens is infection, 265 (72%) 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 April 2016, 993 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.
