Trichinellosis in the Krasnodar Territory

The Krasnodar Territory is a natural focal area for a zooanthroponosis, trichinellosis, the causative agent of which is nematodes Trichinella spiralis (Owen, 1825) and Trichinella pseudospiralis (Garkavi, 1972). According to statistical data, the main source of human infection in the Krasnodar Territory is natural foci of Trichinella, which dwell in wild animals and domestic pigs and birds. In the evolution, Trichinella has acquired a wide range of hosts that have similar food chains and provide for sustained function of the natural focus. A high trichinellosis prevalence is recorded in the mountain and mountain-coastal zones of the Krasnodar Territory. These zones include Tuapsinsky, Lazarevsky, Apsheronsky, Labinsky, Ust-Labinsky, Otradnensky, Belorechensky, Goryacheklyuchevsky and Mostovsky Districts. The research was carried out in the Krasnodar Territory in 2019–2023. Thirty-two patients were hospitalized in the Krasnodar Specialized Clinical Infectious Hospital in 2019; 35 patients in 2020; COVID-19 pandemic was in 2021; 38 patients in 2022; and 34 patients in 2023. Trichinellosis is dangerous to human health and life and causes significant economic damage to pig farming, and therefore it is necessary to strengthen the work of veterinary and public health services to sanitize natural synanthropic foci of trichinellosis.
