Buri Ram has already enforced an order declaring all 23 districts as a controlled zone after detecting the disease in 23 of 77 samples sent for testing.
The samples were collected from cats, dogs and water buffaloes.
Dr Sawat Apiwachaneewong, the chief doctor of Samut Prakarn, warned that people should keep a close watch on their pets as well as other animals, particularly dogs. “They should observe their conditions. If the animals have symptoms of anxiety, insomnia, confusion, agitation or abnormal behaviour and paranoia, they should report to authorities concerned and isolate them,” the doctor said.
