摘要

背景:登革热在印度等国家是一种常见的媒介传播疾病,它发生在特定地区,包括马哈拉施特拉邦的许多地区。2018年7月至8月期间,在瓦尔达县的一个村庄出现发热病例数增加后,怀疑发生了登革热疫情,要求在疫情发展为流行病/更大规模疫情之前进行紧急疫情调查。目的:本研究的目的是发现更多的病例,感染来源,并建议必要的措施来控制登革热疫情。材料和方法:这是一项横断面流行病学研究,我们使用从综合疾病监测计划(IDSP)获得的预先测试、预先设计的流行病学病例表。在开始调查之前,提出了一个案例定义。列线、采集血样、向发热病例分发扑热息痛片和制作现场地图是调查过程中采取的一些重要步骤。结果:64例发热疑似病例中,符合登革热病例定义的有36例。其中23人被送往不同的医院,其中2人死亡。除此之外,其中4人的血液样本中登革热IgM和NS1抗原均呈阳性。以21 ~ 30岁人群影响最大。与男性相比,女性更容易患上这种疾病。House、container和Breteau指数分别为0.26、0.09和0.32。结论:在调查之后,编写了一份详细的报告,并与区卫生当局共享。该报告还载有为控制这次疫情和进一步防止今后发生此类疫情而应采取的必要行动的建议。

Outbreak investigation and containment measures of dengue fever in rural Wardha: A field epidemiological study
Background: Dengue is a common vector-borne disease in countries like India, where it occurs in specific pockets including many in Maharashtra. During July–August 2018, an outbreak of dengue was suspected in a village of Wardha district, following an increase in the number of fever cases from the village, which demanded an urgent outbreak investigation to be carried out before it progressed into an epidemic/larger outbreak. Objectives: The aim of this study was to find out more cases, source of infection and to recommend necessary actions to control the dengue outbreak. Materials and Methods: This was a cross-sectional epidemiological study, where we used pre-tested, pre-designed epidemiological case sheets obtained from Integrated Disease Surveillance Program (IDSP). A case definition was proposed before beginning the investigation. Line listing, collection of blood samples, distribution of paracetamol tablets to fever cases, and making a spot map were some of the important steps carried out during the investigation. Results: Out of a total of 64 suspected fever cases, 36 cases fulfilled the case definition of dengue, set for the purpose of outbreak investigation. Twenty-three of them got admitted in different hospitals among whom two of them died. Apart from that, four of them were found to be positive for both dengue IgM and NS1 antigen in their blood samples. It was age group of 21–30 years which was mostly affected. Compared to males, the female population suffered more from the illness. House, container, and Breteau index were found to be 0.26, 0.09, and 0.32, respectively. Conclusion: Following the investigation, a detailed report was made, which was shared with the district health authority. The report also contained recommendations for necessary actions to be taken to control this outbreak and to further prevent such outbreaks in future.
