摘 要
本文旨在调查犬瘟热的流行病学特征和探讨预防措施。犬瘟热是一种由DNA病毒引起的传染病，具有高传染性和致死率。它通常通过犬之间的接触和空气传播途径传播。一些因素，如季节变化、疫苗接种率和犬群的年龄和健康状况，也会影响犬瘟热的发病率和扩散程度。同时，由于犬瘟热病毒的多种变异株，近年来在犬群中出现了多种病例类型和传播模式，增加了对该病的预防和防控的难度。因此，频繁的疫苗接种、洁净杂忘处置、有效的检疫管控等预防措施被认为是控制该病最有效的手段。本文为犬瘟热的流行病学学术调查提供了有益的信息，以帮助我们更好地了解该疾病的病理学和治疗方法，并为制定有效的疫苗接种和防控策略提供参考。

Abstract：This article aims to investigate the epidemiological characteristics of canine distemper and explore preventive measures. Canine distemper is an infectious disease caused by DNA virus with high infectivity and mortality. It is usually transmitted through contact between dogs and airborne transmission. Some factors, such as seasonal changes, vaccination rates, and the age and health status of the dog population, will also affect the incidence rate and spread of canine distemper. Meanwhile, due to the multiple variants of canine distemper virus, various case types and transmission modes have emerged in dog populations in recent years, increasing the difficulty of preventing and controlling the disease. Therefore, preventive measures such as frequent vaccination, clean disposal, and effective quarantine control are considered the most effective means to control the disease. This article provides useful information for the epidemiological investigation of canine distemper, in order to help us better understand the pathology and treatment methods of the disease, and provide reference for the development of effective vaccination and prevention and control strategies.
