Which country is NOT a member of the PAHO?

The correct response highlights that Portugal is not a member of the Pan American Health Organization (PAHO). PAHO is a specialized international health agency that works within the framework of the World Health Organization (WHO) and focuses on improving health and living standards in the Americas.

Member countries of PAHO include those from North, South, and Central America, as well as the Caribbean. Canada, Peru, and the United States are all part of this organization, reflecting their commitment to collaborative efforts in public health across the American continent. Portugal, however, is a European country and is not part of this regional body, which is exclusively for countries in the Americas. Thus, the distinction between Portugal and the other countries illustrates the geographical scope of PAHO's membership.
