Among 713 equids sampled in northeastern Brazil during 2013-2018, West Nile virus seroprevalence was 4.5% (95% CI 3.1%-6.3%). Mathematical modeling substantiated higher seroprevalence adjacent to an avian migratory route and in areas characterized by forest loss, implying increased risk for zoonotic infections in disturbed areas.
在 2013 年至 2018 年期间,对巴西东北部的 713 匹马属动物进行采样,发现西尼罗河病毒血清阳性率为 4.5%(95%CI 3.1%-6.3%)。数学模型证实,在靠近鸟类迁徙路线和森林减少的地区,血清阳性率更高,这意味着在受干扰的地区,人畜共患病感染的风险增加。
