World Health Organization collaborating centres are institutions that work with the World Health Organization (WHO) in disciplines such as occupational health, food safety, and communicable disease prevention.[1] There are over 700 such centres across 80 countries. Collaborating centres may be research institutes, parts of universities, or academies. The participating institutions partner with WHO to perform research, provide training, or offer other services in furthering the WHO health agenda. These partners are designated by the WHO director-general as a part of a collaborative network.[2] By using networks of established organizations, WHO is able to strengthen the scientific validity of its work and lower the costs of research.
