The COVID-19 pandemic has resulted in a significant number of infections and deaths worldwide, including in Thailand. Currently, the COVID-19 Situation Administration Center (CCSA) has relaxed the disease prevention measures and established standard operating guidelines for various businesses and activities, focusing primarily on public health factors while also considering social and economic factors. This is to help the public and entrepreneurs adapt to the measures designed to prevent the spread of the disease. The Thailand Professional Qualification Institute (Public Organization) recognizes the importance and necessity of preventing infection transmission in the workplace. Therefore, it has developed competencies for adhering to policies and procedures for infection prevention and control, aligning with health and hygiene safety standards. These competencies aim to enhance the professional capabilities of workers and instill confidence among employers.
