Since January 1, dental clinics have been required to provide immunization of employees against hepatitis B and screening against hepatitis C once every six months.

Criteria for infection prevention, control, sterilization, disinfection and medical waste management have been updated for the facilities, the body said. The rules also require the venues to designate professionals responsible for infection control.

The Ministry added new clinics would only be allowed to start operations once they met the updated standards.
