The Regional Centre for Environmental Health Action (CEHA) is a centre of excellence for environmental health. It provides technical support to countries of the Eastern Mediterranean Region to reduce the toll of morbidity and premature mortality caused by modifiable environmental risk factors.

CEHA provides technical guidance, programmatic support, advisory consultations and related services to Member States and partner agencies to heighten the leadership role of the public health sector in regulation, surveillance and management of environmental risks in the fields of:

  • water and sanitation
  • waste management
  • air quality
  • food and chemical safety
  • vector control
  • environmental health emergency management.

It also coordinates WHO’s support in other cross-cutting issues, such as climate change, sustainable development, knowledge management and environmental health risk communications.
