urban yellow fever

基本解释

However, this mosquito species has re-colonized urban areas in the region and poses a renewed risk of urban yellow fever.
然而，随着这一类蚊虫在该地区再次出现，城市型黄热病有可能死灰复燃。
Urban yellow fever: Large epidemics occur when infected people introduce the virus into densely populated areas with a high number of non-immune people and Aedes mosquitoes.
城市型黄热病：如果受感染的人把病毒带入人口稠密的地区，而这些地区有很多人缺乏免疫力，并有伊蚊生存繁殖，就会发生大流行。
The risk of yellow fever transmission in urban areas can be reduced by eliminating potential mosquito breeding sites and applying insecticides to water where they develop in their earliest stages.
通过清除潜在的蚊虫繁殖场所，以及在蚊虫早期孽生的水中喷洒杀虫剂，可降低黄热病传播的风险。
