Dengue fever is a serious public health concern in Vietnam. The 2025 outbreak is projected to be significantly worse than past epidemics, with a sharp increase in cases. This article analyzes the nationwide dengue fever situation and explores the alarming rise in cases.
Nationwide Dengue Fever Situation
Dengue fever is spreading rapidly and severely across the nation. In 2024, the southern region accounted for 41% of the 141,000 cases reported nationwide. The situation is escalating, as the outbreak is no longer confined to the rainy season but is extending into the dry season.
By week 7 of 2025, Ho Chi Minh City has recorded 3,431 dengue fever cases, a 125.3% increase compared to the same period in 2024. This alarming number reflects a significant rise in the outbreak.
The central and Central Highlands regions are also experiencing a surge in dengue cases. Unseasonal rain and prolonged floods during the dry season are creating ideal breeding grounds for mosquitoes. The affected area extends not only to coastal provinces but also to highland regions, with a notable increase in reported cases. Even northern provinces, historically less affected, are now seeing an uptick in cases. Rapid urbanization, population density, and increased trade are contributing to the spread risk.
Climate Change: A Major Driver of the Dengue Crisis
Medical experts cite climate change as a primary cause of the 2025 dengue fever outbreak. Droughts and saltwater intrusion are depleting fresh water sources, forcing residents to store water, which provides ideal breeding grounds for mosquitoes. Unpredictable, irregular rainfall further increases mosquito populations.
These weather changes have created a favorable environment for the development of mosquitoes, especially the Aedes aegypti mosquito, which transmits dengue fever. This has resulted in a sharp increase in cases across various regions.
Risk of Severe Complications and Overburdened Healthcare System
Dengue fever can be re-infected, and re-infections often lead to more severe and complex complications. Patients face unpredictable and potentially serious health consequences. Treating severe cases requires substantial resources, straining the healthcare system. Many lower-tier hospitals lack the capacity to treat severe cases, leading to increased patient referral to higher-tier hospitals and placing a heavy burden on large hospitals.
Severe dengue complications, like acute kidney injury, can significantly impact the health and quality of life of patients.
Controlling the Dengue Outbreak
Controlling the outbreak requires a multifaceted approach extending beyond epidemiological surveillance, vector control (mosquito management), and enhanced treatment capacity. Individual proactive measures such as mosquito and larvae control, improved sanitation, and personal preventative measures are crucial.
While Vietnam has a highly regarded dengue fever treatment protocol, the introduction of a dengue vaccine is anticipated to substantially reduce the likelihood of widespread outbreaks, limit severe cases, and ease the strain on the healthcare system.
Conclusion
Dengue fever is a significant public health issue in Vietnam. Climate change is a critical factor behind the rapid escalation of the current outbreak. Effective control requires coordinated efforts between governmental agencies, communities, and healthcare providers. Raising public awareness about the disease and prevention strategies is vital.
