The World Health Organization (WHO) is a specialized agency of the United Nations that acts as a coordinating authority on international public health. Established on 7 April 1948, with headquarters in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization. The organization develops and promotes the use of evidence-based tools, norms and standards to support Member States to inform health policy options. The Regional Office for Africa (WHO AFRO) worked closely with AU-IBAR in the execution of SPINAP to develop strategies and approaches for capacity building on IDSR/IHR implementation and establishment of virtual regional response teams to public health emergencies. WHO has also been instrumental in the development of the IRCM and is working closely with AU-IBAR and other technical organizations on its work, including promotion of the One Health agenda in Africa.
