Knowing prevalence in wild canids helps us assess the risk of zoonotic spillover. In this study, we updated the infection statistics among red foxes in northern and northeastern Poland since the last monitoring effort at the district (Polish: ) level (2001-2004). We collected faecal samples from 192 red foxes from the districts of Słupsk, Puck, Wejherowo, Kościerzyna, and Kartuzy (Pomorskie Voivodship); 200 individuals from the districts of Bartoszyce, Kętrzyn, Gołdap, Iława, and Węgorzewo (Warmińsko-Mazurskie Voivodship); and 47 individuals from the district of Augustów (Podlaskie Voivodship). Based on nested PCR testing confirmed by Sanger sequencing, we calculated the prevalence with a 95 % confidence interval and compared the results to previous reports. We recorded the highest proportion of infected red foxes in Gołdap District (21/40, 52.5 %, 95 % CI: 37.5 %-67.1 %). The shared prevalence in Puck, Wejherowo, Kościerzyna, and Kartuzy Districts was 10.4 % (19/182, 95 % CI: 6.7 %-15.8 %). One red fox tested positive in Iława District (1/48, 2.1 %, 95 % CI: -0.6 %-11.9 %). We found no statistically significant changes in prevalence in the sampled areas. Our results indicate that prevalence has remained stable in red fox populations throughout the region over the past 20 years.
了解野生犬科动物中的流行情况有助于我们评估人畜共患病溢出的风险。在本研究中，我们更新了自上一次在地区（波兰语：）层面（2001 - 2004年）监测以来波兰北部和东北部赤狐的感染统计数据。我们从斯武普斯克、普克、韦耶罗沃、科斯琴纳和卡尔图济（滨海省）地区收集了192只赤狐的粪便样本；从巴尔托希采、凯特尔津、戈乌达普、伊瓦瓦和韦戈热沃（瓦尔米亚 - 马祖里省）地区收集了200只个体的样本；以及从奥古斯托夫（波德拉谢省）地区收集了47只个体的样本。基于经桑格测序确认的巢式PCR检测，我们计算了患病率及其95%置信区间，并将结果与之前的报告进行比较。我们记录到戈乌达普区感染赤狐的比例最高（21/40，52.5%，95%置信区间：37.5% - 67.1%）。普克、韦耶罗沃、科斯琴纳和卡尔图济区的共同患病率为10.4%（19/182，95%置信区间：6.7% - 15.8%）。在伊瓦瓦区有一只赤狐检测呈阳性（1/48，2.1%，95%置信区间： - 0.6% - 11.9%）。我们发现在采样区域患病率没有统计学上的显著变化。我们的结果表明，在过去20年里，整个地区赤狐种群中的患病率一直保持稳定。
