[Prevalence of Malaria, Intestinal and Urinary parasite infections in Kalifabougou, Mali]

Soil transmitted helminthiasis and schistosomiasis are neglected tropical diseases (NTD), affecting the health status of endemic Malian populations. Mali has a national NTD elimination program using the mass drug administration (MDA) strategy combining Albendazole, Ivermectinand Praziquantel. Malaria still remains a public health problem in Mali. The Community health Center (CSCOM) in Kalifabougouvillage in the Kati health district has benefited from such MDA program since 2010.

To evaluate the prevalence rate of malaria, intestinal and urinary parasite infections in the local population.

We conducted a nested cross sectional and cohort study in May 2011 on volunteers aged three months old to 25 years old. Blood smear (blood), Kato-Katz (Stools) and urine filtration techniques were used to evaluate parasite prevalence. Informed consent and assentment were obtained from the volunteers before their inclusion. All volunteers received treatment against the parasite diseases of interest according to the guidelines of national disease control programs.

A total of 688 volunteers were included. The prevalence rates of parasitic infections were 22.1% [95% CI= 22.06 - 22.12] for Plasmodium falciparum, 9% [95% CI: 8.9-9.034] for Schistosoma haematobium; 3.5% [95% CI: 3.48-3.513] for Hymenolepis nana and 0.1% [95% CI : 0.093-0.107] for Schistoso mamansoni. The prevalence rate of the co-infection Plasmodium falciparum - Schistosoma haematobium was 2.18% [95% CI= 2.17 - 2.19] in Kalifabougou.

Praziquantel and Albendazole-based MDA and Artemisinin based combined therapy (ACTs) could explain theobserved low prevalence of helminthiasis and malaria in Kalifabougou, Mali.
