AB: A veterinary epidemiological survey was conducted as a result of the availability of a large, extensive set of registration data in a paediatric hospital. From 1991-94, 237 dog bite cases represented 0.45% of emergencies in the Trousseau hospital (Paris). For children aged less than 3 years, the frequency of admission to the hospital reached 19.6% (compared to an average of 11.4% for children of all ages), with 75% of the lesions located on the head. These results confirm published results gathered in other countries. The large number of cases gives evidence of a link between sex and age (P< 0.001) and demonstrates the evolution of the sex ratio with age (significant dominance of the male sex only after the age of 12). Analysis of the links between age and certain circumstances (day, month, holidays, season) suggests further studies that take into account the age and maturity of the child (10 years).
