Abstract

This study was aimed to find out the disease prevalence and major symptoms of parvovirus infection in cats treated in The General Animal Hospital of Chiang Rai Rajabhat University over the past 5 years. This study was a retrospective longitudinal study, which was conducted by extracting of data on clinical examinations and laboratory results recorded by veterinarians between 2018 and 2022. Out of 96 cats, which were suspected of parvovirus infection, only 67 were positive to the SensPERT FPV Ag test kit (69.79%; 95%CI = 60.44 – 79.14). The 5-year-prevalence of the disease was 1.01%, compared with the total number of cats treated for different health problems in the same period (67/6,662). The prevalence of the disease was mostly found in 2019 (15/1,021 or 1.47%). The infected cats were found in every month during a year-round, approximately 2 cases/month. The cases were mostly detected between October and March of the following year (71.64%). During the peak period, approximately 8 cases were reported for a month, with the highest cases (12) reported in October. According to the records, major symptoms specified to Parvovirus infection in cats were bloody diarrhea (100%), vomiting (97.01%), and high fever (70.15%), respectively. Unfortunately, there was no history of any vaccination in all cases. This could be a predisposing factor of parvovirus infection found in this study.
