The two-month-old mithun calf lay by the side of the road. Its lifeless glassy eyes stared into nothingness,but its feet twitched occasionally in spasms before death finally came. The young mother stood unsurely beside the calf,licking it at intervals. Scenes like this played out virtually every day in the last few months,reminding us of the epidemic that had besieged this remote corner of Arunachal Pradesh. The killer was a virus (Aphthae epizooticae) belonging to the Picornaviridae family,causing the dreaded Foot-and-mouth disease.
