Incubation can be up to 21 days.

Detection by ELISA testing is minimum of 5 days, anything up to 28 days.

Typical incubation in cattle after contagious contact is 3 days.

"Lameness" is not the best indication, "vertigo" is a better indication and more or less exclusive to FMD.

Historically the disease has only been recognised when it enters pigs, as in 1967 and 2001.
