Increasing Prevalence of Plasmodium vivax among Febrile Patients in Nouakchott, Mauritania

The occurrence of Plasmodium vivax malaria was reported in Nouakchott, Mauritania in the 1990s. Several studies have suggested the frequent occurrence of P. vivax malaria among Nouakchott residents, including those without recent travel history to the southern part of the country where malaria is known to be endemic. To further consolidate the evidence for P. vivax endemicity and the extent of malaria burden in one district in the city of Nouakchott, febrile illnesses were monitored in 2012-2013 in the Teyarett health center. The number of laboratory-confirmed P. vivax cases has attained more than 2,000 cases in 2013. Malaria transmission occurs locally, and P. vivax is diagnosed throughout the year. Plasmodium vivax malaria is endemic in Nouakchott and largely predominates over Plasmodium falciparum.
