(1) Background: Qatar does not have any indigenous cases of dengue; however, the influx of immigrants from dengue endemic countries, the environment, and climate suitability for Aedes vector mosquitoes suggest a potential risk for local transmission. In this study, we investigated various demographic factors to determine the epidemiological features of dengue in Qatar. (2) Methods: In the present retrospective study, we reviewed dengue notification data received at the national surveillance system, Ministry of Public Health, Qatar, between January 2013, and December 2021, and we analyzed the incidence of the dengue disease burden to identify factors that could contribute to the dissemination of the disease in Qatar. (3) Results: A total of 166 dengue fever seropositive cases were recorded during the study period in Qatar. The mean incidence was estimated to be 0.7/100,000 population, which increased from 0.7/100,000 in 2013 to 1.5/100,000 in 2019. The majority of the cases were male, between 20-50 years of age and notified during the hot months (June-September). Most of the patients had fever without hemorrhagic manifestations. There were no dengue related deaths during 2013-2021. (4) Conclusion: Dengue fever occurred more frequently among men than women, and its incidence is low among Qatari nationals. The presence of the most efficient vector, , in Qatar, if confirmed, poses a risk of local outbreaks. Therefore, regular vector surveillance is needed to assess the distribution, biting habits and abundance of vector mosquito species and the risk for mosquito-borne diseases.
(1) 背景：卡塔尔没有本土登革热病例；然而，来自登革热流行国家的移民涌入、环境以及适合埃及伊蚊生存的气候表明存在本地传播的潜在风险。在本研究中，我们调查了各种人口统计学因素，以确定卡塔尔登革热的流行病学特征。(2) 方法：在本次回顾性研究中，我们查阅了卡塔尔公共卫生部国家监测系统在2013年1月至2021年12月期间收到的登革热通报数据，并分析了登革热疾病负担的发病率，以确定可能导致该疾病在卡塔尔传播的因素。(3) 结果：在研究期间，卡塔尔共记录了166例登革热血清阳性病例。平均发病率估计为0.7/10万人口，从2013年的0.7/10万增加到2019年的1.5/10万。大多数病例为男性，年龄在20至50岁之间，且在炎热月份（6月至9月）通报。大多数患者有发热但无出血表现。2013年至2021年期间没有登革热相关死亡病例。(4) 结论：登革热在男性中比女性更频繁发生，卡塔尔国民中的发病率较低。如果在卡塔尔确认存在最有效的传播媒介，就有本地暴发的风险。因此，需要定期进行媒介监测，以评估媒介蚊种的分布、叮咬习性和数量以及蚊媒疾病的风险。
