Dengue Situation Update # 723: 29 May 2025
Situation report
Overview
Dengue is a mosquito-borne viral infection causing a severe flu-like illness and sometimes causing a potentially lethal complication known as severe dengue. The Western Pacific Region continues to face a high burden of mosquito-borne arboviral diseases, particularly dengue. These diseases cause significant morbidity and mortality. WHO’s Western Pacific Regional Office conducts both indicator-based and event-based surveillance for dengue in the region, especially in the Member States where dengue is endemic. This surveillance aims to monitor the overall situation, detect unusual signals in case trends and severity, and assess risks in a timely manner and provide support for response.
This bi-weekly situation report will highlight the most recent developments in the regional response.
