Review of the status of foot and mouth disease in countries of South America and approaches to control and eradication
|Author(s) :||E. Correa Melo, V. Saraiva & V. Astudillo|
Since the signing in 1987 of the Hemispheric Plan for the Eradication of Foot-and-Mouth Disease (PHEFA) by the countries of South America, clinical cases of foot and mouth disease (FMD) have decreased significantly throughout the continent. During the early 1990s, national laboratories diagnosed an average of 766 cases per year in South America. By the late 1990s, this continent-wide average had fallen to 130. By the end of the 1990s, the international community recognised Argentina, Chile, Guyana and Uruguay as free of FMD without vaccination. In 1999, clinical signs of FMD were absent in 60% of all cattle of the continent. These cattle represented 41% of all herds in South America and extended over 60% of the geographical area of the continent.
