GOAT POX 
Synonyms: WVariola caprina; Variola de chévre; Pockenkrankheit 
bet Ziegen. 
Characterization. Variola of the goat is a disease peculiar to this 
species. It is not transmitted to sheep nor sheep pox to goats. It 
attacks males, kids and females, especially during the period of lacta- 
tion. 
History. Goat pox has often been encountered in Norway. Han- 
sen has described a number of outbreaks in that country. It has also 
been found in Algeria, in Spain and in Persia. 
Etiology. The virus is transmitted with the saliva of the infected 
animals. It is transmitted by direct contact. Cutaneous inocula- 
tions result in the development of pox eruptions associated with mild 
general symptoms. In some cases sheep have been successfully 
inoculated experimentally. The disease spreads rapidly when intro- 
duced into a flock. 
Symptoms. The manifestations resemble very closely those of 
sheep pox. The eruptions are characteristic. These appear on the 
mouth, mammary gland, abdomen, inside of the thighs and occa- 
sionally on other parts. 
The period of incubation is from 3 to 7 days. 
Its period of duration is from 1 to 3 weeks. The mortality is low. 
Morbid anatomy. In addition to the vesicles and pustules, already 
described, pustules sometimes occur on the mucous membrane of the 
stomach and intestine. Occasionally the pustules are confluent. A 
phlegmonous mastitis is sometimes present. 
Diagnosis. The diagnosis is made by the symptoms and eruptions. 
It is to be differentiated from foot-and-mouth disease and from other 
skin eruptions.

eruptive disease characterized by the variolous eruptions. It has not
