A diarrhoea outbreak in Phuket is easing, while health officials have not yet determined its cause.
Dr Kittisak Aksornwong said on Thursday that the number of diarrhoea patients in Phuket began to rise on June 6, with 383 cases, and the cases peaked at 1,238 on June 9.
Starting from June 10, the number of patients started to decline.
The largest group of patients, accounting for just over a quarter of all cases, were aged 25-34 years old.
Most patients had mild symptoms and around 13% of all patients were admitted to hospitals.
Despite the improving situation, disease investigation and surveillance are ongoing, the doctor said.
Health officials had examined samples from six ice factories and three majoring drinking water plants in Phuket, but they did not find any signs of diseases.
