Abstract

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. 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. 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). 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.

Highlights

Latin America and the Caribbean have been the epicenter of emerging epidemics of arboviral diseases since December 2013 [1]
From 1 January 2016 to 21 July 2019, a total of 109,557 cases of Dengue virus (DENV) were reported, 44,834 of them in 2016 (40.9%), decreasing to 5,217 in 2017 (4.8%) and increasing up to 28,603 in the ongoing 2019 (26.1%), for incidence rates varying from 522.75 cases/100,000 pop in 2016, to 312.32 cases/100,000 pop till the epidemiological week (EW) 28 of 2019 (Figure 1A)
The highest peak was reached on the epidemiological weeks (EW) 28°, 2019 (5,299 cases; 57.89 cases/100,000 pop) (Figure 1B)

Introduction

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 >1,000 cases/100,000 pop (1%).
