Assessment of schistosomiasis and intestinal helminths following mass drug administration in the Centre and Plateau Central regions of Burkina Faso

Abstract

Schistosomiasis is the most important waterborne disease in Sub-Saharan Africa. Transmission is governed by the spatial distribution of specific freshwater snails that act as intermediate hosts and human water contact patterns. In developing countries, such as Burkina Faso it remains a serious health problem, which management face important gaps. The main of theses gaps is the lack of reliable information about prevalence. Then, this study has been undertaken in order to determine the prevalence of schistosomiasis in the Centre and Plateau Central regions in Burkina Faso. A cross-sectional descriptive study was conducted in the Plateau Central and Centre regions of Burkina Faso to assess the status of schistosomiasis and intestinal worms among school age children. 1,455 school-age children were selected to participate to the study. Results shows that prevalence of Schistosoma haematobium in the Plateau Central and Centre regions were 4% and 0.6% respectively, with an overall prevalence of 2.3% (95% CI: 1.5% -3.1%) in two regions. The following intestinal parasites were found in stools with various prevalence: Schistosoma mansoni 0.1% (95% CI: 0% -0.3%) and Ancylostoma duodenale 0.1% (95% CI: 0% -0.2%). The prevalence of urinary schistosomiasis in the Centre and Plateau Central regions had been greatly reduced from the previous level in the published data since the large-scale population treatment initiated in 2004. The study confirmed the success in controlling the disease by preventive chemotherapy. However, the progress toward its elimination requires that the implementation of a monitoring and evaluation system focused on sentinel sites, and aiming at quantifying the impact of treatment, be gradually coupled with a monitoring system to identify any outbreak of residual transmission.

Persistance de la schistosomiase urinaire en zones endémiques soumises aux traitements de masse répétés au Mali

“…La comparaison entre les trois sites d'étude a montré que la prévalence de l'infection à S. haematobium dans le village de M'Pèba (72,36%) était nettement supérieure à celles des villages de Guénidanga (52,61%) et de Kalabougou (24,4%) ; P< 10 -6 (Tableau 4). Ces taux de prévalence de S. haematobium sont nettement supérieurs à ceux obtenus par Zongo et al (2016) dans deux régions du Burkina Faso soient 4% et 0,6% avec une moyenne de 2,3% (95% CI: 1,5% -3,1%). Pour tous les villages confondus, la prévalence de l'infection à S. haematobium entre sujets de sexe différent n'était pas significativement différente.…”

Clinicopathologic Features of Urinary Bladder Cancer at a Tertiary Hospital in Western Kenya

“…Whereas the current study adopted a prospective design, that was conducted in Nairobi adopted a ten-year retrospective design which is often fraught with incomplete data that may cause proportionate variations on the factors of interest. Squamous cell carcinoma proportion in this study could be attributed to chronic urinary tract infections from either bacteria or Schistosoma haematobium parasite which are prevalent in Western Kenya which is within the Lake Victoria basin 10,37 . This study reported that nine in ten (91.1%) of the participants had low grade tumors with 8.9% presenting with high grade tumors.…”

Epidemiology of tsetse flies in the transmission of trypanosomiasis: technical review of The Gambia experience

“…About 50 million cattle and 70 million sheep and goats are at risk for AAT and an estimated three million cattle die from the disease annually in Africa (Simarro et al, 2010). As the parasite maneuvers ways to avoid the animal's immune system, and in the absence of a suitable vaccine, surveillance, speedy diagnosis and treatment with existing drugs are not effective and vector control efforts will go a long way in decreasing the incidence of AAT (Oyibo et al, 2009;Zongo et al, 2016). AAT still remains by far the most devastating parasitic and neglected zoonotic disease in Africa, affecting both humans and livestock.…”
