An unprecedented dengue outbreak occurred in 2010 in Port Sudan city, Sudan. Dengue incidence was 94 cases per 10 000 observed over 17 epidemiological weeks (total cases = 3 765). We report here the impact of the vector control response plan to the outbreak, which mainly entailed house inspection and insecticide space spraying. In total 3 048 houses were inspected during vector surveillance and 19 794 larvae and 3 240 pupae of Aedes aegypti were collected. Entomological indices decreased during the period: house index declined from 100% to 16% (F= 57.8, P < 0.001) and pupal/person (P/P) index from 0.77 to 0.10 (F= 3.06, P < 0.01) in weeks 9 and 21 respectively. This decline was accompanied by a decrease in cases from a peak of 341 cases in week 13 to zero in week 29 and the end of the outbreak. There was a significant correlation between the entomological parameters and dengue incidence (R2 = 0.83, F= 23.9, P < 0.001). Integrated epidemiological and vector surveillance is essential to an effective dengue control programme
2010 年，苏丹港口城市发生了一场前所未有的登革热疫情。在 17 周的流行病学观察期间，登革热发病率为每 10000 人中有 94 例（总病例数=3765 例）。我们在此报告了该疫情中控制病媒响应计划的影响，该计划主要包括房屋检查和杀虫剂空间喷洒。在病媒监测期间，共检查了 3048 所房屋，收集了 19794 只埃及伊蚊幼虫和 3240 只蛹。在整个期间，昆虫学指数下降：房屋指数从 100%下降到 16%（F=57.8，P<0.001），第 9 周和第 21 周的蛹/人（P/P）指数分别从 0.77 下降到 0.10（F=3.06，P<0.01）。这种下降伴随着病例数从第 13 周的 341 例高峰下降到第 29 周和疫情结束时的零例。病媒学参数与登革热发病率之间存在显著相关性（R2=0.83，F=23.9，P<0.001）。综合流行病学和病媒监测对于有效的登革热控制计划至关重要。
