Abstract:

Background: Canine parvovirus (CPV) disease is highly contagious and primarily affects young, unvaccinated dogs. It can cause severe bloody diarrhea or vomiting and high mortality rates. Objective: This study aimed to analyze suspected and confirmed CPV cases in Cebu, Philippines, and identify factors associated with infection. Methods: This retrospective analytical study covered suspected and confirmed CPV cases tested using commercially available test kits in Cebu, Philippines, from 2018 to 2024. Clinical records from participating veterinary facilities were examined. Qualifying cases were processed, coded, and imported into statistical software for further analysis. Results: A total of 1,014 cases were studied, of which 72.7% of the dogs tested positive for CPV. Breed susceptibility varied, with Shih Tzus and mixed breeds exhibiting higher positivity rates. Vaccination appeared to significantly reduce the risk of CPV, as unvaccinated dogs had higher infection rates than vaccinated dogs. Statistical analysis indicated that younger dogs with incomplete vaccination were more likely to be CPVpositive. Conclusion: The findings underscore the importance of vaccinating puppies, conducting targeted public awareness campaigns, and enhancing veterinary services to mitigate CPV incidence. Future research may investigate seasonal variations, environmental factors, and long-term immunity in recovered dogs to develop better disease prevention strategies.
