Dengue and chikungunya viruses among febrile travelers entering Iran (2015-2021): Evidence of multiple introductions from different countries.

ABSTRACT:

Objectives

Recent outbreaks of dengue, chikungunya, and Zika have underscored the growing threat to public health. This study retrospectively describes the presence of these viruses among febrile travelers entering Iran between 2015 and 2021. Although Iran had no local transmission until 2024, several factors increased the risk of outbreaks, including the presence of mosquito vectors, favorable climate, and inadequate traveler control measures. Climate change and increased humidity have further increased this risk.

Methods

A multiplex real-time reverse transcription-polymerase chain reaction assay was used to screen 245 serum samples from febrile travelers, identifying dengue and chikungunya viruses in 13.9% of the travelers.

Results

Dengue was more prevalent (9%) tha
