[Toxocariasis in Swiss children]
Insights
Toxocariasis, a parasitic infection, was found in rural Swiss children with dog contact or geophagia. Urban children showed no infection, highlighting environmental risk factors for toxocariasis.
Area of Science:
- Parasitology
- Pediatrics
- Epidemiology
Background:
- Toxocariasis is a zoonotic parasitic infection caused by the roundworm Toxocara.
- Understanding the prevalence and risk factors in pediatric populations is crucial for public health.
- Previous studies have indicated potential links between environmental factors and Toxocara infections.
Observation:
- Six clinical cases of toxocariasis in Swiss children were reported.
- An epidemiological study compared infection rates in urban (Basel) and rural (Entlebuch) settings.
- Clinical observations noted excessive and sustained eosinophilia as a primary symptom.
Findings:
- No seropositive results for toxocariasis were found in 70 urban children from Basel.
- Four out of 68 children tested in rural Entlebuch were seropositive for toxocariasis.
- Seropositive children reported close contact with dogs, particularly puppies, and/or geophagia.
Implications:
- The study suggests a higher risk of toxocariasis in rural environments, potentially linked to specific lifestyle factors.
- Findings underscore the importance of considering Toxocara infection in children presenting with eosinophilia, especially those with potential exposure.
- Further research into environmental and behavioral determinants of toxocariasis in Switzerland is warranted.
Abstract:
A report is presented on 6 clinical observations of toxocariasis in Swiss children and on an epidemiological study of toxocara infections conducted in an urban and a rural area. The ELISA test in 70 children from the city of Basel revealed no seropositive result. In contrast, 4 of 68 children tested in the village of Entlebuch were seropositive. All reported close and intensive contact with dogs (mainly puppies) or geophagia. The main presenting symptom in our 6 clinical observations was excessive and sustained eosinophilia. Additional clinical and epidemiological aspects, the clinical picture and current therapy are discussed.
