The incubation period of Camelpox is between 3 and 15 days. The resulting infection can be classified as acute or generalized. Generalized infections are usually found in camels over the age of three, and are characterized by swollen lymph nodes, fever, and the development of skin lesions. The lesions begin as papules, but develop into pustules. These external symptoms usually begin on the head and neck, but eventually spread throughout the body, being especially concentrated on the limbs and genitalia. Without treatment, the animal will generally recover from the infection in 4 to 6 weeks.
