Knowledge, attitudes, and practices of municipal veterinary practitioners towards echinococcosis

Abstract

Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are among the most relevant zoonoses in Europe. According to the European Food Safety Authority (EFSA), Echinococcus granulosus sensu lato causing CE is the most significant foodborne parasite in South-Western Europe, followed by Echinococcus multilocularis, the etiological agent of AE. Among the challenges and opportunities highlighted in the literature to combat these diseases are the need to evaluate and increase awareness of stakeholders. In Portugal, Municipal Veterinary Practitioners (MVP) are the animal health authority at the municipality level, playing a crucial role in diagnosis, prevention and control of infectious diseases in animals, helping to mitigate transmission to humans. However, their knowledge, attitudes, and practices (KAP) towards CE, as well as awareness of AE expansion across Europe, remain overlooked. In this work, a cross-sectional study was conducted for the first time in Portugal to bridge knowledge gaps concerning CE and AE, using an online self-administered questionnaire collecting information on the municipal kennel, KAP towards CE, and understanding of AE epidemiology. Eighty-three MVP from mainland and islands completed the questionnaire, with highest representability from the central-northern region. MVP had, on average, a medium to high level of knowledge of CE but acquaintance with AE was insufficient, although echinococcosis was frequently mentioned as target of health education sessions (77.0%). A high rate (60%) of reported entries into municipal kennels of stray dogs originating from countries with AE endemic areas was registered, suggesting that the presence of these potentially AE-infected stray dogs pose public health risks. Most kennels did not perform routine coprological analysis or faecal matter disinfection after dog internal deworming. The lack of proper training and well-conceived written plans of infection control and prevention were evidenced in several kennels. Altogether, our findings highlight the need to update knowledge and practice of MVP under the One Health approach, through reinforced education, training and communication involving all stakeholders.
