Trichinellosis in hospitalized patients from Western Romania: A retrospective study

Trichinellosis is a public health problem and an economic issue in porcine animal production and food safety. The aim of this retrospective study was to evaluate the current epidemiologic, laboratory, clinical and therapeutic aspects of human trichinellosis in Western Romania. We retrospectively investigated the medical records of patients hospitalized in infectious diseases hospitals from three counties in Western Romania, between January 1st, 2012 and December 31st, 2016. A total of 83 patients diagnosed with trichinellosis were included in the study. Pork meat was the food source of infection in 76 (91.6%) patients and wild boar meat in 4 (4.8%). Patients were aged between 2 and 78 years; 48 (57.8%) were males and 27 (32.5%) came from an urban area. The most frequent symptoms included myalgia in 66 (79.5%) patients, fever in 55 (66.3%), eyelid edema in 40 (48.2%) and asthenia in 35 (42.2%). Two patients died and the others had favorable outcome. Although the number of reported cases has decreased in the past years, trichinellosis remains an important public health problem in Western Romania. Educational programs for both swine breeders and consumers are imperative, and implementation of strict hygienic measures aimed to control infection transmission are strongly recommended.
