An outbreak of trichinellosis in a military unit

Abstract

In December 2001, an outbreak of trichinellosis spreaded in a military unit. The aim of this paper was to show possibilities and consequences of trichinellosis infestations in military units during peace time, as well as to improve knowledge and awareness of medical corps personnel, commanders and soldiers about this disease. A descriptive and analytical epidemiological models were used to find out a source of outbreak and to identify the ways of its transmission. This outbreak was caused by the contaminated raw smoked sausage which had not undergone health inspection and brought from civilians to a military unit. Thirty-eight persons were exposed, twenty-one affected and hospitalized. The most frequent symptoms reported were fever (76.2%), myalgia (76.2%), palpebral edema (42.8%), face edema (19.0%) and diarrhea (14.3%). Test for indirect immunofluorescence was positive in 14.3% and ELISA test was positive in 28.6% of the patients. Eosinophilia was present in 85.7% of the affected. IgE values were increased in 28.6% and CPK values were increased in 61.9% of the diseased. All of the 17 exposed undiseased had negative laboratory analyses for trichinellosis. We propose intensifying health education and continuing the implementation of duly supervised and evaluated self-check programs. A well-tuned, fast-reacting epidemiological monitoring system has to be obligatory.
