Insights
Soil-transmitted nematode infections are common in Buea District primary pupils, with rural areas most affected. Health education alongside Mebendazole treatment improves control of Ascaris and Trichuris infections.
Area of Science:
- * Parasitology
- * Public Health
- * Pediatric Medicine
Background:
- * Soil-transmitted nematodes pose a significant health burden, particularly in school-aged children.
- * Understanding prevalence and intensity across different geographic settings is crucial for effective control strategies.
- * Previous interventions have focused on chemotherapy, but integration with health education requires further investigation.
Purpose of the Study:
- * To determine the prevalence, intensity, and geographical distribution of soil-transmitted nematodes in primary school children.
- * To evaluate the efficacy of Mebendazole treatment and the added benefit of health education in controlling these infections.
Main Methods:
- * A cross-sectional experimental study was conducted in the Buea Health District.
- * Three hundred and forty primary school children participated in the study.
- * Interventions included Mebendazole treatment and health education.
Main Results:
- * The overall prevalence of soil-transmitted nematodes was 59.1%, with significantly higher rates in rural areas (P<0.01).
- * Ascaris lumbricoides was the most prevalent parasite; Mebendazole effectively reduced Ascaris and Trichuris infections but not hookworm.
- * Health education, combined with Mebendazole, significantly slowed re-infection rates for Ascaris and Trichuris compared to anthelmintic treatment alone.
Conclusions:
- * Soil-transmitted nematodes, including Ascaris lumbricoides, Trichuris trichiura, and hookworms, are highly prevalent in the study area.
- * Mebendazole is effective against some nematodes but not hookworms.
- * Health education is a valuable adjunct to chemotherapy for sustained control of soil-transmitted nematode infections in children.
Objective:
To investigate the prevalence, intensity of infection and control of soil-transmitted nematodes in primary school pupils of urban, suburban and rural localities.
Setting:
Buea Health District.
Design:
A cross section experimental study.
Subjects:
Three hundred and forty primary school children.
Intervention:
Mebendazole treatment complemented with health education.
Results:
The overall prevalence rate of soil-transmitted nematodes in the Buea Health District was 59.1%. The infection rate was significantly different in the urban, suburban and rural localities of the health district (P<0.01), with the rural area having the highest rate of infection. Ascaris lumbricoides was the most predominant parasite. The intensity of infection with the various helminth species was not significantly different between children of urban, suburban and rural localities. Mebendazole treatment significantly reduced the intensities of infection with Ascaris and Trichuris (P<0.05). The treatment, however, was ineffective against hookworm infection. Re-infection rate with Ascaris and Trichuris was slower in children who additionally received health education than in those who received only anthelminthic treatment.
Conclusion:
Ascaris lumbricoides, Trichuris trichiura and hookworms are the predominant nematodes reported in children of urban, suburban and rural localities in the health district. Health education is advocated as a complement to chemotherapy in the control of soil-transmitted nematodes.
