Foot and mouth disease (FMD) is an extremely important transboundary animal disease (TAD) caused by foot and mouth disease virus (FMDV). The FMD virus is extremely variable, developing in seven different serotypes, viz., U, A, C, Asia1, To the south African Territories (SAT) 1, SAT two, and SITTING 3, internationally (Gao ain al., 2016), but their geographical distributions are not the same and are clinically indistinguishable. With the exception of Asia one particular, all the FMDV serotypes have already been recorded in Africa, which serotypes To, A, SAT 1 and SAT a couple of occur in Western world Africa.
FMD is quite contagious and affects cloven-hoofed animals, including domesticated varieties (such as cattle, lamb, goats and pigs), regarding 70 species of wildlife, which includes African zoysia (Fenner ain al., 93, Grubman and Baxt, 2004).
The illness is medically characterized by speedy rise of temperature, accompanied by formation and subsequent eruption of vesicular lesions in the mouth and on the tongue, nose, snout, feet and teats (Grubman and Baxt, 2004). These lesions result in copious amounts of salivation, feed refusal and lameness.
The most predisposed hosts among the list of domestic family pets are the cattle, while swines are the most resistant (Donaldson and Alexandersen, 2002). The clinical symptoms in cattle are overt and appear right away, whereas in sheep and goats, the disease is often clinically unapparent (Grubman and Baxt, 2004) and might go unnoticed. Although FMD rarely brings about death of adult pets or animals, it is one of the most feared animals disease due to the fast spread, nearly fully morbidity (especially in naïve populations), mortality in young animals as well as its debilitating effects (CFSPH, 2014). Normally, influenced animals recover but may become debilitated, causing a reduction in productivity (James and Rushton, 2002).
Most likely, this is the most economically devastating disease of livestock primarily due to the control measures utilized during breakouts and loss resulting from interdiction of international trade of animals and animal goods (Thompson ain al., 2002). FMD offers occurred in almost every part of the community where domestic animals are held, currently affecting more than 95 countries (mostly developing) around the world but continues to be eradicated by the more designed countries (Jamal and Belsham, 2013). Yet , as proved by the 2001 epidemic in the united kingdom, France as well as the Netherlands and the outbreaks in South Korea and Asia 2000 (Knowles et ‘s., 2001), the illness can be reintroduced from native to the island areas into previously free of charge countries causing huge economic losses.
