We report three cases of yellow fever (YF) in a family traveling from the city of Sao Paulo, Brazil (without previous vaccination) to an endemic area, acquiring the disease and presenting mild-to-moderate symptoms. Despite posing the intermittent risk of YF in endemic areas, it also alerts to the threat of introduction and spread of YF in the urban cycle, when infected travelers return to non-endemic areas where potential vectors are highly prevalent.
我们报告了三例来自巴西圣保罗市（无既往接种史）的旅行者感染黄热病（YF）的病例，他们在疫区感染了该病并出现了轻至中度症状。尽管在疫区存在间歇性的 YF 风险，但它也提醒了人们注意 YF 在城市循环中的输入和传播的威胁，当感染旅行者返回潜在媒介高度流行的非疫区时。
