Vietnam has reported more than 50,000 cases of dengue fever in the first five months of 2026, a significant increase compared to the previous year.
Ho Chi Minh City has recorded four deaths related to the disease.
Dengue activity has started earlier than usual and has spread to northern regions of the country. The DENV-2 serotype is dominant and is associated with a higher risk of severe illness.
Transmission patterns have changed, affecting children and adults alike. Drivers include climate change, hot and humid weather, rainfall, urbanization, and inadequate infrastructure. Pilot vaccination and mosquito control programs are being implemented.
