Bangkok: "Influenza" cases are trending higher than last year; at-risk groups are advised to get vaccinated. The number of influenza cases in 2026 is projected to be higher than last year. Those at risk are advised to get vaccinated promptly.

According to Thai News Agency, Ms. Lalida Periswiwatana, Deputy Spokesperson for the Prime Minister's Office, revealed that the Department of Disease Control, Ministry of Public Health, warned that the influenza situation in 2026 is likely to see a higher number of patients than last year. She advised the public, especially vulnerable groups, to get vaccinated against the disease to reduce the severity and spread of the illness.

The deputy spokesperson stated that, according to disease surveillance data from January 1st to March 9th, 2026, there were 137,276 reported cases, equivalent to a morbidity rate of 211.48 per 100,000 population, and 8 reported deaths. The age groups with the highest number of cases were 5-9 years old, 0-4 years old, and 10-14 years old.

Provinces with high infection rates include Phayao, Phitsanulok, Chiang Mai, and Lamphun, with outbreaks most prevalent in communities and educational institutions.

The majority of those who died were elderly, aged 60 and above, and those with underlying conditions such as lung disease, heart disease, or immunodeficiency disorders, who were at a higher risk of experiencing severe symptoms than other groups.

The deputy spokesperson stated that in 2025, Thailand reported 1,194,342 cases of influenza and 129 deaths. The situation in 2026 is projected to see an increase in cases due to the resumption of social activities and inter-regional travel.

The government requests the cooperation of the public in protecting themselves from influenza by frequently washing hands, wearing face masks, avoiding crowded areas, and if experiencing symptoms such as fever, cough, sore throat, or runny nose, resting and avoiding close contact with others.

'If you experience high fever, cough, shortness of breath, or your symptoms do not improve within 1-2 days, you should see a doctor immediately, especially if you are in a high-risk group such as the elderly, young children, pregnant women, and those with underlying medical conditions,' Ms. Lalida said.
