The role of veterinarians in zoonosis prevention: Advising families of immunocompromised children with pets

Background: Pet ownership is widespread, offering numerous benefits to individuals and families. However, the risk of zoonotic diseases must be carefully considered, especially for immunosuppressed patients. Knowledge gaps in preventive measures for zoonoses have been identified, underscoring the vital role of veterinarians in addressing this issue.

Objectives: This study aimed to assess the knowledge and recommendations of veterinarians regarding pet ownership by immunocompromised individuals. Additionally, we compared these insights with responses from European healthcare professionals specializing in pediatric transplant recipients.

Methods: We conducted an observational, cross-sectional study involving small animal veterinarians in Spain. An online survey was administered to gather information on veterinarians' knowledge of zoonoses and their recommendations for immunocompromised pet owners.

Results: A survey of 514 individuals was collected from experienced veterinarians mainly working in primary care clinics. Surprisingly, 63% of respondents did not routinely inquire about the presence of immunocompromised individuals among pet owners, although 54% offered specific recommendations for this group. Most respondents adhered to deworming guidelines for pets owned by immunocompromised individuals and demonstrated sound practices in Leishmania and Leptospira prevention, as well as the avoidance of raw food. However, gaps were noted concerning Bordetella bronchiseptica vaccination. Notably, veterinarians outperformed medical professionals in their knowledge of zoonotic cases and identification of zoonotic microorganisms. The presence of specific recommendations in veterinary clinics was viewed positively by nearly all respondents.

Conclusions: Our findings indicate that veterinarians possess a superior understanding of zoonotic pathogens and exhibit greater proficiency in diagnosing zoonoses compared with physicians. They stay well-informed about recommendations outlined in established guidelines and are more likely to provide written recommendations in their clinics than physicians. Nevertheless, knowledge gaps among veterinarians emphasize the need for enhanced communication between medical and veterinary professionals. Reinforcing the "One Health" concept is imperative, with veterinarians playing a pivotal role in this collaborative effort.
