South America has a favourable position with respect to foot-and-mouth disease (FMD) compared with other FMD-affected regions due to the elimination of endemic clinical presentation of the disease. South America has reached the final stage of control and aims to eradicate the disease in the region under the provisions of the Hemispheric Program for the Eradication of FMD 2011-2020 (PHEFA). This programme aims at bringing eradication to completion, thereby eliminating the pool of foot-and-mouth disease genotypes active in South America. This plan includes a regional political agreement that provides strategies and technical guidelines for the eradication of foot-and-mouth disease from South America. It incorporates knowledge and experience regarding the disease's history and its connection with the different production systems, animal movement and trade. The Pan American Foot and Mouth Disease Center has led the control and eradication programmes, providing the framework for designing national and subregional programmes that have led to significant progress in controlling the disease in South America. The current situation is the result of several factors, including the proper implementation of a national control programmes, good veterinary infrastructure in most countries and public-private participation in the process of eradicating the disease. Notwithstanding the favourable health status, there are significant challenges for the goal of eradication. At this stage, South American countries should enhance their surveillance strategies particularly through the use of target or risk-based surveys that contribute to increase the degree of sensitivity in the search for viral circulation in the context of absence of clinical occurrence of FMD.
