Methods We systematically collected the data about dengue cases, the assessment of epidemic foci, and the management and evaluation from the municipal mosquito vector control team for emergency response in Guangzhou, Guangdong province, China, 2019. We assessed the effectiveness of the team's performance by epidemic duration and cumulative case number at the epidemic focus. The rank sum test was used to analyze whether the epidemic situation was affected by the response, also different response, from the team. Results In 2019, a total of 1 478 local cases were reported in Guangzhou, distributed in 680 epidemic foci, including 143 (21.03%) foci of outbreaks. The team dealt with 28 epidemic foci, accounting for 4.12% of the total foci. The density of adult mosquitoes was significantly reduced after mosquito vector control from the team (t=6.909, P<0.001). Both the epidemic duration and case number were significantly lower in the foci where the treatment began within eight days after the epidemic emerged and there were at least two round actions than in the foci without the treatment (Z=3.984, 2.345, 2.048, and 3.586, all P<0.05). Conclusion Early and full-scale control of mosquitoes at dengue epidemic foci by the municipal mosquito vector control team for emergency response, in the form of government-purchased services, can contain the community spread of dengue. In future dengue prevention and control by mosquito vector control, more personnel should be added, and other control forces should be united to establish an effective mechanism of surveillance, evaluation, and emergency response. %U http://www.bmsw.net.cn/EN/10.11853/j.issn.1003.8280.2020.03.003
