Aeromonas hydrophila sepsis after ERCP and laparoscopic cholecystectomy: a case report.

Onchocerciasis due to is transmitted from person to person by repeated bites of infected black flies, mainly in tropical areas (). The number of people infected with onchocerciasis is estimated at 37 million in 36 countries, 99% of whom live in 31 countries in sub-Saharan Africa. Approximately 500,000 of these people suffer significant vision loss and half are blind (). The number of people at risk of onchocerciasis infection is estimated at 85.6 million in the world (). In Mali, the public health importance of onchocerciasis was reported as early as the 1970s (). Onchocerciasis was initially considered endemic in five regions in Kayes, Koulikoro, Sikasso, Ségou and Mopti. According to the Mali National onchocerciasis control program (PNLO in French), 34 health districts out of the 75 in the country were endemic for onchocerciasis between 1971 and 1987 with a total of 4,589,963 inhabitants at risk of onchocerciasis (). Before control interventions (vector and mass drug administration), onchocerciasis prevalence varied notably across the five health districts. Kéniéba had the highest levels, typically exceeding 45–60%, while Séféto showed high prevalence ranging from about 30 to 60%. Sélingué presented intermediate values, generally between 15 and 50%, and Dioïla had moderate prevalence around 15–30%. In contrast, Kati showed the lowest levels, with prevalence usually between less than 5 and 15% (National onchocerciasis control data).
