Summary
Schistosomiasis infection, particularly Schistosoma haematobium, is highly prevalent in Cabo Delgado schools. Despite this, students and teachers demonstrate good knowledge of the disease, recognizing it as a public health issue.
Area of Science:
- Tropical Medicine
- Infectious Diseases
- Public Health
Background:
- Schistosomiasis is a significant parasitic disease affecting tropical and subtropical regions.
- Understanding infection prevalence and knowledge is crucial for effective control strategies.
Purpose of the Study:
- To assess schistosomiasis infection extent in schools in Cabo Delgado, Mozambique.
- To evaluate student and teacher knowledge regarding schistosomiasis.
- To identify potential shifts in disease distribution.
Main Methods:
- Conducted a survey across 12 schools in Cabo Delgado.
- Utilized validated questionnaires combined with parasitological stool and urine examinations.
- Assessed knowledge levels among students and teachers.
Main Results:
- Very high prevalences of Schistosoma haematobium infection were recorded in all surveyed schools (lowest at 77.5%).
- Questionnaires did not differentiate 'high risk' schools due to uniform high prevalence.
- Students and teachers exhibited good knowledge of schistosomiasis, recognizing it as a public health concern.
- Schistosoma mansoni infection was rare, but its vector, Biomphalaria, was identified in the area.
Conclusions:
- Schistosomiasis, primarily S. haematobium, poses a substantial public health challenge in Cabo Delgado.
- Effective disease control requires updated mapping due to potential changes post-conflict.
- The presence of the S. mansoni vector warrants further investigation and monitoring.
