the regional offices and in specialized centres. The RD is also the direct supervising authority – concomitantly with the WHO Director-General – of all the heads of WHO country offices, known as WHO Representatives, within the region. The strong position of the regional offices has been criticized in WHO history for undermining its effectiveness and led to unsuccessful attempts to integrate them more strongly within 'One WHO'. Disease specific programmes such as the smallpox eradication programme or the 1980s Global Programme on AIDS were set up with more direct, vertical structures that bypassed the regional offices. Employees The WHO employs 7,000 people in 149 countries and regions to carry out its principles. In support of the principle of a tobacco-free work environment, the WHO does not recruit cigarette smokers. The organization has previously instigated the Framework Convention on Tobacco Control in 2003. Goodwill Ambassadors The WHO operates "Goodwill Ambassadors"; members of the arts, sports, or other fields of public life aimed at drawing attention to the WHO's initiatives and projects. There are currently five Goodwill Ambassadors (Jet Li, Nancy Brinker, Peng Liyuan, Yohei Sasakawa and the Vienna Philharmonic Orchestra) and a further ambassador associated with a partnership project (Craig David). On 21 October 2017, the director-general Tedros Adhanom Ghebreyesus appointed the then Zimbabwean president Robert Mugabe as a WHO Goodwill Ambassador to help promote the fight against non-communicable diseases. The appointment address praised Mugabe for his commitment to public health in Zimbabwe. The appointment attracted widespread condemnation and criticism in WHO member states and international organizations due to Robert Mugabe's poor record on human rights and presiding over a decline in Zimbabwe's public health. Due to the outcry, the following day the appointment was revoked.

It has conducted lectures by noted researchers and published findings, recommendations. The founder, Dr. S. William A. Gunn has been its president. In 1983, Murray Eden was awarded the WHO Medical Society medal, for his work as consultant on research and development for WHO's director-general.

It also operates several liaison offices, including those with the European Union, United Nations and a single office covering the World Bank and International Monetary Fund.
