The figures were revealed on Sunday by Dr Suphan Srithamma, director-general of the Health Depatment, and Dr Narong Apikulvanich, director of the centre for the prevention and mitigation of medical calamities from political rallies.
As for a People's Democratic Reform Committee guard who was shot in the chest and seriously wounded at 11.30pm on Saturday at the Lat Phrao intersection, the man has undergone surgery and is recovering in an intensive care unit, they said.
According to Dr Suphan, medical teams have been assigned to the rally site. Mobile rescue operations teams have been mobilised from several provinces such as Kanchanaburi, Ranong and Lop Buri to provide emergency treatment.
There are sufficient medical teams to cope with any emergency cases which may arise, he said.
"We are confident we can cope with the situation. We have also coordinated with hospitals in surrounding areas where patients can be referred to in case they cannot be admitted by hospitals in Bangkok," said Dr Suphan.
