Almost 2,000 people had contracted seasonal flu in the lower Northeast - seven of whom died, the head of Office of Disease Prevention and Control 5 in Nakhon Ratchasima said yesterday.
Dr Theerawat Walaisathien said 1,919 people had been struck down from January 1 to June 6.
Nakhon Ratchasima has had 1,278 cases (seven deaths), Chaiyaphum 170 cases, Buri Ram 335 cases and Surin 136 cases.
The disease prevalence doubled compared to the same period last year when the figure for the four provinces was 987 (and no deaths), he said.
With the Public Health Ministry having already distributed flu vaccines to all medical facilities, it was expected that all main risk groups – small children, the elderly and those with chronic diseases – would be vaccinated by July, he added.
