Salmonella infection causes epidemic death in wild songbirds, with potential to spread to humans. In February 2021, public health officials in Oregon and Washington, USA, isolated a strain of Salmonella enterica serovar Typhimurium from humans and a wild songbird. Investigation by public health partners ultimately identified 30 illnesses in 12 states linked to an epidemic of Salmonella Typhimurium in songbirds. We report a multistate outbreak of human salmonellosis associated with songbirds, resulting from direct handling of sick and dead birds or indirect contact with contaminated birdfeeders. Companion animals might have contributed to the spread of Salmonella between songbirds and patients; the outbreak strain was detected in 1 ill dog, and a cat became ill after contact with a wild bird. This outbreak highlights a One Health issue where actions like regular cleaning of birdfeeders might reduce the health risk to wildlife, companion animals, and humans.
沙门氏菌感染导致野生鸣禽流行死亡，并有可能传播给人类。2021 年 2 月，美国俄勒冈州和华盛顿州的公共卫生官员从人类和野生鸣禽中分离出一株肠炎沙门氏菌血清型鼠伤寒沙门氏菌。公共卫生合作伙伴的调查最终确定了与鸣禽中沙门氏菌 Typhimurium 流行有关的 12 个州的 30 例疾病。我们报告了一起与鸣禽有关的人类沙门氏菌病多州暴发，这是由于直接处理患病和死亡的鸟类或间接接触受污染的鸟食器所致。伴侣动物可能在沙门氏菌在鸣禽和患者之间的传播中起了作用；在 1 只患病的狗中检测到了暴发菌株，而 1 只猫在接触野生鸟类后患病。此次暴发突出了一个“同一健康”问题，即定期清洁鸟食器等措施可能会降低野生动物、伴侣动物和人类的健康风险。
