Regional offices

Uncharacteristically for a UN Agency, the six Regional Offices of the WHO enjoy remarkable autonomy. Each Regional Office is headed by a Regional Director (RD), who is elected by the Regional Committee for a once-renewable five-year term. The name of the RD-elect is transmitted to the WHO Executive Board in Geneva, which proceeds to confirm the appointment. It is rare that an elected Regional Director is not confirmed.

Each Regional Committee of the WHO consists of all the Health Department heads, in all the governments of the countries that constitute the Region. Aside from electing the Regional Director, the Regional Committee is also in charge of setting the guidelines for the implementation, within the region, of the Health and other policies adopted by the World Health Assembly. The Regional Committee also serves as a progress review board for the actions of the WHO within the Region.

The Regional Director is effectively the head of the WHO for his or her Region. The RD manages and/or supervises a staff of health and other experts at the regional headquarters and in specialized centers. 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 Regional Offices are:

Regional Office for Africa (AFRO)I, with headquarters in Brazzaville, Republic of Congo. AFRO includes most of Africa, with the exception of Egypt, Sudan, Tunisia, the Libyan Arab Jamahiriya, and Morocco which belong to EMRO. Somalia is also not counted as it does not have an official government, though it is in the process of getting one.
Regional Office for Europe (EURO), with headquarters in Copenhagen, Denmark.
Regional Office for South East Asia (SEARO), with headquarters in New Delhi, India. North Korea is served by SEARO.
Regional Office for the Eastern Mediterranean (EMRO), with headquarters in Cairo, Egypt. EMRO includes the countries of Africa, and particularly in the Maghreb, that are not included in AFRO, as well as the countries of the Middle East.
Regional Office for Western Pacific (WPRO), with headquarters in Manila, Philippines. WPRO covers all the Asian countries not served by SEARO and EMRO, and all the countries in Oceania. South Korea is served by WPRO.
Regional Office for the Americas (AMRO), with headquarters in Washington, D.C., USA. It is better known as the Pan American Health Organization (PAHO). Since it predates the establishment of WHO, PAHO is by far the most autonomous of the 6 regional offices.

Country offices

The World Health Organization operates 147 country and liaison offices in all its regions. The presence of a country office is generally motivated by a need, stated by the member country. There will generally be one WHO country office in the capital, occasionally accompanied by satellite-offices in the provinces or sub-regions of the country in question.

The country office is headed by a WHO Representative (WR), who is a trained physician, not a national of that country, who holds diplomatic rank and is due privileges and immunities similar to those of an Ambassador Extraordinary and Plenipotentiary. In most countries, the WR (like Representatives of other UN agencies) is de facto and/or de jure treated like an Ambassador - the distinction here being that instead of being an Ambassador of one sovereign country to another, the WR is a senior UN civil servant, who serves as the "Ambassador" of the WHO to the country to which he or she is accredited. Hence, the title of Resident Representative, or simply Representative.

The country office consists of the WR, and several health and other experts, both foreign and local, as well as the necessary support staff. The main functions of WHO country offices include being the primary adviser of that country's government in matters of health and pharmaceutical policies.

International liaison offices serve largely the same purpose as country offices, but generally on a smaller scale. These are often found in countries that want WHO presence and cooperation, but do not have the major health system flaws that require the presence of a full-blown country office. Liaison offices are headed by a liaison officer, who is a national from that particular country, without diplomatic immunity.
