Bangkok: The Department of Disease Control cautions the public about the increased risk of influenza outbreaks anticipated during the rainy season, urging precautionary measures following a report of over 170,000 cases and 16 deaths in 2026.

According to Thai News Agency, Dr. Montien Kanasawasdi, Director-General of the Department of Disease Control, highlighted data from the Digital Disease Surveillance System (DDS), which recorded a cumulative total of 171,731 influenza cases and 16 deaths as of May 28, 2026. The age groups most affected include children aged 5-9 years, 0-4 years, and 10-14 years. Despite a downward trend compared to the previous year, the number of cases remains higher than the five-year median, with the Influenza B virus being the most prevalent strain.

Dr. Kanasawasdi noted ongoing outbreaks in several areas, predicting an increase in cases during the rainy season, which is typically the peak period for influenza. The virus spreads easily through respiratory droplets and direct contact with infected individuals, making crowded environments like schools and public transportation hotspots for transmission. Common symptoms include sudden high fever, cough, sore throat, and body aches, with potential complications such as pneumonia posing significant risks to high-risk groups like young children and the elderly.

Dr. Direk Khamphaen, Deputy Director-General of the Department of Disease Control, emphasized preventive measures to mitigate the spread of influenza. He recommended practices such as wearing face masks in crowded places, frequent hand washing, avoiding close contact with infected individuals, and resting if symptoms occur. Importantly, annual vaccination is advised for high-risk groups to prevent severe illness.
