In which city is the headquarters of the World Health Organization located?

The headquarters of the World Health Organization (WHO) is located in Geneva, Switzerland. This city was chosen as it has long been an important hub for international diplomacy and public health efforts. Establishing the WHO in Geneva allowed it to be at the heart of many global health initiatives and collaborations. Geneva is home to numerous international organizations, which enhances the WHO's ability to cooperate with various health organizations, governements, and non-profits worldwide.

The other cities listed, while significant in their own rights, do not host the headquarters of the WHO. For example, New York is known for housing the United Nations, Paris is famous for its cultural and political importance, particularly in terms of historical treaties and European governance, and London is a major player in global finance and politics. However, none of these cities serve as the central location for global health governance that Geneva does.
