Nakhon Ratchasima, Surin, Buri Ram, and Chaiyaphum were the worst affected, with about 6,938 patients. Somsak also called on people showing flu-like symptoms to stay home to prevent spreading the virus. Health officials have also been speeding up the supply of vaccines to sensitive groups, particularly children and senior citizens.
New patients have increased by about 15,000 per week, compared to 10,000 per week during the same period in 2024.
Anyone with chronic diseases such as asthma or diabetes, pregnant women, and children are at high risk of the virus and are more likely to develop severe symptoms.
Yong Poovorawan, a virologist at the Chulalongkorn University Faculty of Medicine, posted an advisory on Facebook on February 9 saying that travellers to countries in the northern hemisphere should get a flu shot at least two weeks before going abroad.

In another Facebook post, Yong also said there is no specific treatment for the said influenza, and patients will be treated according to symptoms.
“Influenza is seasonal. It spreads in the cold season in the northern and southern hemispheres,” Yong said.
