Answer: Virus
Notes: Recently, 16 chitals (spotted deer) died at Rajiv Gandhi Zoological Park in Pune due to Foot and Mouth Disease (FMD), as confirmed by lab reports. Foot and Mouth Disease (FMD) is a highly contagious viral disease affecting all cloven-hoofed animals like cattle, goats, sheep, deer, and pigs. It is caused by an aphthovirus from the Picornaviridae family. The World Organisation for Animal Health (WOAH) first gave official recognition to this disease.
