Canine parvovirus (CPV) is an important and often fatal pathogen of domestic dogs. It is resistant in the environment and cross-species transmission has been indicated in some canid populations, but never in Australia. The aim of this study was to determine if an association exists between 1. reported CPV cases in domestic dogs, and 2. the wild canid distribution in New South Wales (NSW), Australia. Reported CPV cases, and reports of the presence of wild dogs and the red fox (), were extracted from a voluntary surveillance database and a voluntary pest reporting system, respectively. A total of 1,984 CPV cases in domestic dogs, and 3,593 fox and 3,075 wild dog sightings were reported between 2011 and 2016. Postcodes in which CPV cases were reported were significantly (P = 0.0002) more likely to report wild dogs (odds ratio 2.07, 95% CI 1.41-3.03). Overall, CPV cases were significantly ( < 0.05) correlated with both fox reports (r 0.225) and wild dog reports (r 0.247). The strength of association varied by geographical region and year; the strongest correlations were found in the mid-North Coast region (r 0.607 for wild dogs) and in 2016 (r 0.481 for foxes). Further serological and virological testing is required to confirm the apparent and plausible association between domestic CPV cases and wild canid distribution found in this study.
犬细小病毒（CPV）是家犬的一种重要且常致命的病原体。它在环境中具有抗性，在一些犬科动物种群中已出现跨物种传播，但在澳大利亚从未发生过。本研究的目的是确定：1. 家犬中报告的CPV病例与2. 澳大利亚新南威尔士州（NSW）野生犬科动物分布之间是否存在关联。分别从一个自愿监测数据库和一个自愿虫害报告系统中提取报告的CPV病例以及野狗和赤狐（）出现的报告。2011年至2016年间，共报告了1984例家犬CPV病例，以及3593次狐狸目击和3075次野狗目击。报告有CPV病例的邮政编码地区报告野狗的可能性显著更高（P = 0.0002）（优势比2.07，95%置信区间1.41 - 3.03）。总体而言，CPV病例与狐狸报告（r = 0.225）和野狗报告（r = 0.247）均显著相关（P < 0.05）。关联强度因地理区域和年份而异；在中北海岸地区发现最强的相关性（野狗的r = 0.607）以及在2016年（狐狸的r = 0.481）。需要进一步的血清学和病毒学检测来确认本研究中发现的家犬CPV病例与野生犬科动物分布之间明显且合理的关联。
