Global re-emergence of dengue fever: The need for a rapid response and surveillance

Dengue fever virus (DENV) is a mosquito-borne virus mostly spread by Aedes aegypti. According to the World Health Organization, DENV is found primarily in urban and semiurban areas in tropical and subtropical climates globally, putting approximately half of the world's population at risk, where about 100–400 million cases of the disease occur annually. In 2023 alone, there were over five million cases of dengue fever reported in more than 80 countries and territories worldwide. This is due to an ongoing outbreak of the disease potentiated by unanticipated spike in cases. It is crucial to understand DENV transmission patterns to manage public health effectively. Here, we provide an overview of the recent global outbreak of DENV and propose the integrated/coordinated health system (One Health) as a recommendation for effective prevention and control measure.
