摘要

霍乱是尼泊尔的一个重大公共卫生问题，特别是在加德满都谷地。加德满都谷地几乎每年都有复发疫情的记录，但关于发生地点的数据有限。因此，在本研究中，我们旨在确定加德满都谷地霍乱暴发病例的地理空间分布。方法收集2022年6 - 10月通过医院监测系统向流行病学和疾病控制科报告的霍乱病例资料。对病例家庭进行访问，并通过移动应用程序记录病例家庭的全球定位系统（GPS）。使用开源GIS软件（QGIS版本3.32.0）绘制地理位置图。结果对加德满都谷地75例霍乱病例进行了分析。大多数病例为男性（53.2%），中位年龄32岁。15-34岁年龄组受影响最大。空间分析显示，大多数病例集中在加德满都区，特别是11、12和13病区，呈零星分布。时间趋势显示，第28周病例数下降，随后从第29周开始增加，在整个疫情期间累积病例数逐渐上升。结论本研究突出了加德满都谷地霍乱暴发的人口统计学、时间和空间动态。这些发现对于在这种情况下加强公共卫生规划和应对霍乱预防和控制战略至关重要。

Geo-temporal analysis of cholera cases in Kathmandu Valley: An outbreak study 2022

Introduction

Cholera is a significant public health problem in Nepal, particularly in Kathmandu valley. Recurrent outbreaks have been recorded in Kathmandu valley almost every year, however there is limited data on the locations of the occurrence. Hence, in this study, we aim to determine the geo-spatial distribution of cholera outbreak cases in Kathmandu valley.

Methods

Data on cholera cases reported to Epidemiology and Disease Control Division through the hospital-based surveillance system during the period of June to October of 2022 were included in the study. Households of the cases were visited and the global positioning system (GPS) of the case household were recorded through mobile application. The geolocations were mapped using open-source GIS software (QGIS version 3.32.0).

Results

A total of 75 cholera cases within the Kathmandu Valley were analyzed. The majority of cases were male (53.2 %), with a median age of 32 years. The 15–34 age group was most affected. Spatial analysis revealed that most cases were concentrated in the Kathmandu district, particularly in wards 11, 12, and 13, with sporadic distribution patterns. Temporal trends showed a decline in cases in week 28 followed by an increase from week 29, with cumulative cases progressively rising throughout the outbreak.

Conclusion

This study highlights the cholera outbreak's demographic, temporal, and spatial dynamics in the Kathmandu Valley. The findings are vital for enhancing public health planning and response strategies for cholera prevention and control in such settings.
