IMPACT OF EPIDEMIOLOGICAL FACTORS ON TOXOCARIASIS IN CHILDREN
Journal Title: Przegląd Pediatryczny - Year 2008, Vol 38, Issue 4
Abstract
Introduction: Humans, especially children, become infected by Toxocara ingesting either infective eggs from soil, on dirty hands, raw vegetables, or after consuming undercooked poultry, cattle, pig or rabbit meat containing larvae. The highest risk of infection with these nematodes concerns young children (2-7 years old), who play in sandboxes and have contact with young dogs or cats. The aim of the study was to analyse the dynamics of Toxocara canis infection with reference to environmental conditions, and to define risk factors of this infection in case of children. Material and methods: In the period I (1994-1998 years), and in the period II (2004-2007 years) all children diagnosed and treated in our hospital were serologicaly examined for the presence of anti Toxocara antibodies. During the first period the analysis comprised 49 out of 450 children, in the second – 42 out of 3634 children. In both groups of patients the place of living (rural/urban), type of domiciles (household, block of flats), presence of garden or farm areas, data on contacts with domestic dogs and/or cats were noted. Results: In the years 2004-2007, T. canis infection was significantly more frequent than in the years 1994-1998 (p<0.01). In case of both periods among children with toxocariasis boys prevail. 67.35% and 69% children with toxocariasis lived in town rather than in the countryside in two analysed periods. The families of infected children kept dogs with nearly the same frequency in case of both periods. In both periods statistically no significant differences in the prevalence of Toxocara infection with reference to the place of living were observed. Conclusions: In last ten years, frequenting of Toxocara canis infection with children explored in ICZMP decreased. Toxocariasis appears more often in case of boys than girls living in a city. Having pets doesn’t increase the risk of Toxocara infection.
