Variola caprina
Variola caprina (Goat Pox) is a contagious viral disease caused by a pox virus that affects goats. The virus usually spreads via the respiratory system, and sometimes spreads through abraded skin. It is most likely to occur in crowded stock. Sources of the virus include cutaneous lesions, saliva, nasal secretions and faeces. There are two types of the disease; the papulo-vesicular form and nodular form (stone pox). The incubation period is usually between 8–13 days, but it may be as short as 4 days.
