The Epidemiology of Fmd
ثبت نشده
چکیده
FMD virus is an aphtovirus within the picornaviridae family. The most important characteristics in the epidemiology of the disease include the rapid growth of the virus, its stability under a variety of conditions and the occurrence of serotypes (Donaldson, 1991). There are seven serotypes and several subtypes within each. The infections caused by different serotypes are clinically indistinguishable. The animals that survive a FMD infection become permanently infected to the particular strain that cause the infection; however, there is no cross-protection between serotypes.
