Methods The national Aedes surveillance data was statistically analyzed using SPSS 18.0 software. Results In 2018, the mean Breteau index (BI) of Aedes mosquitoes was 3.25, and the mean mosquito ovitrap index (MOI) was 5.19. In category I provinces with the high dengue risk, the mean BI of Hainan throughout the year, that of Zhejiang from the first half of April to the first half of November, that of Fujian from April to November (except the second half of April), that of Yunnan from the first half of July to the first half of October, and that of Guangxi from June to August and the second half of September were all higher than 5, indicating a risk of dengue transmission; the BI of 9 surveillance cities in Guangdong from March to November indicated a risk of dengue transmission; the mean MOI of Guangxi from the first half of May to the second half of September and that of Guangdong from the second half of May to the first half of October were all higher than 5, indicating a risk of dengue transmission. In category Ⅱ provinces with the medium dengue risk, the BI of Hubei and Sichuan from May to September, that of Shanghai from June to September, and that of Chongqing, Anhui, Jiangxi, Henan, and Hunan from May to October indicated a risk of dengue transmission; the BI of Jiangsu indicated no risk of dengue transmission during the study period. The MOI of Guizhou from June to September, that of Henan in July and September, and that of Hunan in July indicated a risk of dengue transmission. In category Ⅲ province with the low dengue risk, the BI of Shaanxi from July to September, that of Shandong from July to August, and that of Hebei from June to September were higher than 10, indicating a risk of dengue outbreak; the MOI of Beijing in August indicated a risk of dengue transmission. The adult density of Aedes in Guangxi from the second half of May to the second half of September (except the first half of July and the first half of September), that of Hainan from April to October, that of Ningbo, Zhejiang, from August to October, that of Hangzhou from July to November, that of Chongqing from May to September, that of Hubei and Jiangsu from June to September, that of Sichuan in July, and that of Shaanxi from July to August were higher than 2 mosquitoes per net per hour. Conclusion In 2018, the dengue transmission risk varies in different months in the three categories of provinces in China. Overall, the southern provinces have higher risk than the northern provinces, and the eastern coastal provinces have higher risk than the central and western provinces. It is suggested that Aedes surveillance and risk assessment should be strengthened in key provinces and cities to ensure sustainable control of Aedes for the prevention and control of Aedes-borne diseases in China. %U http://www.bmsw.net.cn/EN/10.11853/j.issn.1003.8280.2019.02.004
