title: Clinical manifestations of foot-and-mouth disease during the 2010/2011 epidemic in the Republic of Korea.
abstract: We reviewed the clinical signs of the foot-and-mouth disease (FMD) incidences in the Republic of Korea occurring from November 2010 to April 2011. Profuse salivation, vesiculation, lameness or ataxia, and ulceration were the most commonly observed clinical signs of FMD among the infected animals, irrespective of the species. The clinical signs of FMD manifested more clearly in the dairy cattle and pigs compared to the beef cattle, deer and goats on infected farms. About 54% of the infected dairy farms reported vesicles on the teats as the primary clinical sign, while vesiculation on the nose, including the snout and muzzle, was the major lesion observed in infected beef cattle and pig farms. The teat and feet were the second most frequently vesiculated body parts on infected pigs. Although the average age of the first-to-appear clinical lesion in the animals in the beef and dairy cattle farms subjected to vaccination was higher than that observed in the animals in the farms not subjected to vaccination, a reverse pattern was observed in the pig farms. In this study, the clinical signs of FMD were described on the basis of the subjective observations by the farm workers. The present results highlight the clinical signs expected on specific body parts of different types of susceptible animals, and therefore, they may be useful for generating public awareness, particularly among farm workers, as well as for early detection of future FMD outbreaks.
