Most of the cases were sporadic, accounting for 92.20% (733/795). The incidence peak was from March to August, accounting for 67.80% (539/795). In addition to Changdao County, cases of brucellosis had been reported in 12 counties (cities, districts). The incidence rate of the top three counties (cities, districts) were 5.20/100 000 (369 cases, accounting for 46.42%) in Laizhou City, 2.13/100 000 (97 cases, accounting for 12.20%) in Zhaoyuan City, and 1.77/100 000 (62 cases, accounting for 7.80%) in Penglai City. The male and female sex ratio was 2.82 to 1.00 (587 to 208). The age of onset was mainly 40 - 69 years old, accounting for 79.62% (633/795). Occupation was mainly farmers, accounting for 83.90% (667/795). Cases were mainly found in local medical institutions, accounting for 89.56% (712/795). The average interval between onset and diagnosis was 17 days, the longest was 40 days in 2012, and the shortest was 12 days in 2018.Conclusions:From 2011 to 2018, except Changdao County, 12 counties (cities and districts) in Yantai City had reported brucellosis cases. The incidence peak was in spring and summer, mainly in middle-aged and elderly people, so we should carry out targeted prevention and control strategies for different areas and key populations.
