The nature, cause, origin, and progress of Rinderpest.
Rinderpest virus (RPV) is a single-stranded RNA virus in the family Paramyxoviridae, genus Morbillivirus. It is immunologically related to canine distemper virus, human measles virus, peste des petits ruminants virus, and marine mammal morbilliviruses.
There is no report of RPV infection in humans.
Rinderpest virus is a relatively fragile virus, and does not persist in the environment. Sunlight is lethal, and the virus is very sensitive to heat. The virus can be detected in the milk of recovered animals up to 45 days after recovery and occurs in milk 1–2 days before clinical signs develop. The virus is sensitive to a wide range of disinfectants.
The incubation period is 3-15 days (the period between infection and the appearance of symptoms of the disease). Shedding of virus in tears, nasal secretions, saliva, urine and feces begins 1-2 days before fever occurs. The blood and all tissues are infectious before the appearance of clinical signs
