Study reveals alarming prevalence of schistosomiasis in Benin, requiring an urgent response

The thesis of Moudachirou Ibikounle from the University of Abomey-Calavi highlights a prevalence of 85% for S. haematobium and 30% for S. mansoni in Benin, underscoring the urgency of an appropriate response to this public health challenge. This research, resulting from a Franco-African co-supervision, proposes targeted control strategies to reduce transmission.

Schistosomiasis represents a major public health issue in Benin, with significant economic and social implications. Moudachirou Ibikounle's research analyzes the epidemiology and host-parasite interactions of these diseases, confirming the presence of two species of human schistosomes, S. haematobium and S. mansoni, with alarming prevalence rates.

The results show that S. haematobium has a prevalence of 85%, while S. mansoni reaches 30%. Snail vectors, such as Bulinus forskalii and Bulinus globosus, are identified as key to transmission. The study also reveals variable compatibility of S. haematobium populations with different Bulinus groups, opening the way to targeted control strategies.

The strategic implications of this research are significant. Decision-makers must incorporate these findings into prevention and treatment programs to reduce the costs associated with the disease. An integrated approach, taking into account cercarial chronobiology and human behavior, is essential to optimize public health interventions.

« "The prevalence of S. haematobium reaching 85% in Benin underscores the urgency of targeted interventions to combat schistosomiasis," says Moudachirou Ibikounle. »

« "This research provides crucial data for decision-makers, enabling them to effectively guide public health investments in Benin," notes the Lektaris team. »
