Background

After serious epidemics of chikungunya (CHIKV) and Zika (ZIKV) in the Americas, dengue (DENV) have reemerged in most countries. We analyzed the incidence, incidence rates, and evolution of DENV cases in Honduras from 2015 to 2018 and the ongoing 2019 epidemic.

Methods

Using epidemiological weeks (EW) surveillance data on the DENV in Honduras, we estimated incidence rates (cases/100,000 population), and developed maps at national, departmental, and municipal levels.

Results

From January 1, 2016 to July 21, 2019, a total of 109,557 cases of DENV were reported, 28,603 in 2019, with an incidence rate of 312.32 cases/100,000 population this year; 0.13% laboratory-confirmed. The highest peak was reached on the EW 28°, 2019 (5299 cases; 57.89 cases/100,000 population). The department with the highest number of cases and incidence rate was Cortes (8404 cases, 479.68 cases/100,000 population in 2019).

Discussion

The pattern and evolution of DENV epidemic in 2019 in Honduras has been similar to that which occurred for in 2015. As previously reported, this epidemic involved the north and central areas of the country predominantly, reaching municipality incidences there >1000 cases/100,000 population (or 1%). Studies using geographical information systems linked with clinical disease characteristics are necessary to obtain accurate epidemiological data for public health systems. Such information is also useful for assessment of risk for travelers who visit specific areas in a destination country.

使用地理信息系统 (GIS) 的 2016-2019 年洪都拉斯登革热的空间分布——登革热流行对公共卫生和旅行医学的影响

背景

基孔肯雅热（CHIKV）和寨卡病毒（ZIKV）在美洲爆发严重疫情后，登革热（DENV）在大多数国家卷土重来。我们分析了洪都拉斯 2015 年至 2018 年以及 2019 年持续流行的 DENV 病例的发病率、发病率和演变情况。

方法

利用洪都拉斯 DENV 的流行病学周 (EW) 监测数据，我们估算了发病率（病例数/100,000 人），并绘制了国家、部门和市级地图。

结果

2016年1月1日至2019年7月21日，共报告DENV病例109557例，2019年为28603例，今年发病率为312.32例/10万人；0.13% 实验室确认。最高峰出现在 2019 年 EW 28°（5299 例；57.89 例/100,000 人口）。病例数和发病率最高的部门是科尔特斯（8404例，2019年479.68例/10万人）。

讨论

2019 年洪都拉斯 DENV 流行的模式和演变与 2015 年的流行相似。如先前报道，该流行病主要涉及该国北部和中部地区，到达该地区的城市发病率>1000 例/100,000 人（或 1%）。必须使用与临床疾病特征相关联的地理信息系统进行研究，才能为公共卫生系统获取准确的流行病学数据。此类信息对于访问目的地国家/地区特定区域的旅行者的风险评估也很有用。
