Abstract: Malaria is still one of the major public health problems which is reemerging in Americas due to its vast forest area and tourism. The objective of this paper is to present a birds-eye view of the Malaria situation in the W.H.O. Region of the Americas. The methods included online searches related to Malaria for each country such as from the W.H.O., the Centers for Disease Control and Prevention, USA (CDC), the National Health Service, UK (NHS) and journal articles as well as national program documents. The W.H.O. Region of the Americas consists of forty-nine countries. Despite the stringent efforts to eliminate Malaria cases, only twelve countries were given Malaria free certificates by W.H.O. Most of the countries of the Americas were able to eliminate Malaria more than half a century ago and in a large part this was due to advances in improving sanitation so that breeding places for the mosquitoes ceased to exist. Thirty-one countries are free of indigenous Malaria while the remaining eighteen are progressing towards that target. Therefore, it is seen that many countries in the Region of the Americas are yet to receive certification of Malaria elimination. Close coordination and collaboration between the public health departments and stakeholders is required to eliminate Malaria in the Americas.Abstract: Malaria is still one of the major public health problems which is reemerging in Americas due to its vast forest area and tourism.
