Análisis epidemiológico retrospectivo de Distemper Canino en la ciudad de Pachuca de Soto, Estado de Hidalgo

Abstract

Canine distemper virus (CDV) is the causative agent of one of the most spread, highly contagious and lethal viral disease in canines, whose morbidity varies between 25-75% and mortality between 50-90%. The aim of the present study was to carry out an epidemiological study of CDV from a Veterinary Hospital in the city of Pachuca de Soto, State of Hidalgo. The information was obtained from 7280 medical records of canine patients treated during the 2017-2018 period, of which 65 met the positive case criteria for the CDV. An observational, cross-sectional epidemiological study with a retrospective search of cases was carried out. It was determined that 8 out of every 1000 patients attending the clinic were positive for CDV, observing that a higher frequency of males with 63%, with Relative Risk (RR) of 0.67 and an Odds Ratio (OR) of 0.47 , patients under 6 months have the highest frequency of cases with 62% (RR of 8.0 and OR of 19.2); Despite the variability of the breeds within the analysis performed, the highest frequency was found in mongrel dogs with 52% (RR of 1.79 and OR of 2.66), on the other hand, it was determined that seasonality influences the degree of presentation of this disease, being greater in winter with 45% of cases (RR 1.81 and OR 2.47). In conclusion, in the Veterinary Hospital under study, the CDV affects male Creole dogs less than seven months of age unvaccinated more and the disease occurs most frequently in winter
