Public Health Service DEPARTMENT OF HEALTH & HUMAN SERVICES Centers for Disease Control And Prevention (CDC) Memorandum Date: November 6, 2017 From: WHO Collaborating Center for Dracunculiasis Eradication, CDC Subject: GUINEA WORM WRAP-UP #251 To: Addressees Every uncontained Guinea worm from any source can spread infection! GUINEA WORM OUTBREAK IN ETHIOPIA After eleven consecutive months with no reported cases of Guinea worm disease, the Ethiopian Dracunculiasis Eradication Program (EDEP) has detected a total of 14 apparent cases between September 25 and October 16, 2017. At least one of the case patients allegedly had a worm emerge as early as mid-August. All of the patients are males between 16 and 40 years old, 11 are ethnic Oromo, and 1 is Agnuak; only one was contained. Nine patients were detected in Oromia Region, where they reside, while 3 were detected in Gambella Region (Figure 1, Tables 1 and 2). This outbreak was only discovered when the index case appeared at the regional hospital in Gambella town for treatment on September 25. Subsequently it was learned that two patients with broken worms had been treated at health centers in Yeti kebele (sub-district) in Anfilloo woreda (district) of Oromia Region before September 25 and sent home. The two patients were not reported to health authorities, they were not queried as to the potential sources of their infection, and no containment measures were taken.
