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，隨著這一類蚊蟲在該地區再次出現，城市型黃熱病有可能死灰複燃。
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.
城市型黃熱病：如果受感染的人把病毒帶入人口稠密的地區，而這些地區有很多人缺乏免疫力，竝有伊蚊生存繁殖，就會發生大流行。
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.
通過清除潛在的蚊蟲繁殖場所，以及在蚊蟲早期孽生的水中噴灑殺蟲劑，可降低黃熱病傳播的風險。
