Schistosomiasis risk is present in the country, the full extent of Schistosomiasis risk is unknown due to fragmentary research:
S. haematobium is present in the southern part of Mauritania. The highest rates are reported from populated areas along the Sénégal River, the Karakoro River valley including the settlements along their tributaries and diversion canals. Other regions reporting cases include Inchiri, western Hodh Ech, Chargui, southwestern Hodh el Gharbi, western Adrar, Assaba, and western Tagant.S. mansoni has been reported in the southern region of Trarza along the Sénégal River. The full extent of Schistosomiasis risk in the Mauritania is unknown.
The nomadic life of Mauritanian herdspeople facilitates the spread of infection. Travellers should consider all oases and settlement areas at risk. Additional snail intermediate host: Bulinus umbilicatus.
