Our staff provides technical expertise and content knowledge in support of the WHO Global Plan of Action on Workers' Health-with an emphasis on the healthcare sector.

Currently, our Center is working to enhance capacity among PAHO employees who are themselves healthcare workers, regarding their own safety and health and sustaining their advances through safety and health committee functions and responsibilities

We are also assisting in providing toxicology, infection control training in collaboration with PAHO partners and WHO Collaborating Centers in occupational health in the Caribbean and the Americas.

This activity also includes provision of technical training and assistance in occupational and environmental cancer control and prevention.
