Vietnam dengue fever outbreaks expand across provinces
Overview
By mid-September 2026, dengue fever outbreaks continued to expand across Vietnam, driven by hot, humid weather and the rainy season. In Ho Chi Minh City, the situation remains severe, with over 31,000 cases recorded since the beginning of the year. Medical facilities, including the Hospital for Tropical Diseases, have treated critical cases involving shock, multi-organ failure, and respiratory distress, sometimes requiring expensive interventions such as VV-ECMO.
In Dak Lak province, the Center for Disease Control reported 6,112 cases as of September 10, including two deaths. High-risk areas include several communes and wards within the province. This follows a period of rapid growth in the region, which previously saw a “207% increase compared to July” in August.
In Hanoi, health authorities continue to warn of potential outbreaks due to unpredictable weather, high population density, and students returning for the new school year. Regional case counts also remain elevated in Dong Nai, which has recorded more than 9,000 cases and five deaths this year.
Medical experts emphasize that there is no specific treatment for dengue fever. They warn that the disease can progress to a severe stage between the third and seventh day of symptoms. Vulnerable groups—including children, the elderly, pregnant women, and individuals with underlying conditions like type 2 diabetes—face higher risks of complications such as liver damage, respiratory failure, and coagulation disorders.
