Human trichinellosis in children from Timis County, Romania: epidemiological features from a retrospective study conducted between 1990 and 2006.

Trichinellosis, a parasitic zoonosis caused by the ingestion of inadequately cooked pork containing Trichinella larvae, has been a serious health problem in Timis, the largest of the Romanian counties. The authors conducted a survey on trichinellosis in children from Timis County, emphasising epidemiological aspects. Medical records from 106 children who were hospitalised at the Victor Babes Infectious Diseases Hospital in Timisoara from 1990 to 2006 were investigated. Children affected by trichinellosis were predominantly in the 10- to 14-year-old age group (34.9%). Most patients (59.43%) were inhabitants of urban areas and 59.43% of cases were males. Winter was the season when the number of cases peaked (76.42%). The highest prevalence of disease (18.87%) was recorded in 1994. For 38.68% of the patients, eosinophilia ranged between 10% and 20%. The length of hospitalisation ranged from 8 to 14 days in 50.94% of cases. In recent years, human trichinellosis has decreased in Timis County as a result of an improvement in the implementation of hygiene measures. The highest prevalence of the disease recorded in 1994 can be explained by an economic transition period when national pig farms began to close. Winter was the season with the highest prevalence because people eat a lot of pork during the traditional holidays.
