World Health Organization (WHO) Collaborating Centres enable WHO to extend its reach and bolster efforts to improve human health around the world. Building on over three decades of collaboration, NIEHS was designated as a WHO Collaborating Centre for Environmental Health Sciences in September, 2013. The Collaborating Centre provides a focal point and resource for the Institute to fulfill its strategic goals in global environmental health and help translate research findings into effective public health interventions. The Pan-American Health Organization (PAHO), the WHO Regional Office for the Americas, helps coordinate the activities of WHO Collaborating Centres in the Americas.
