- Peste des Petits Ruminants is a highly contagious disease that mainly affects goats, camels, sheeps and small ruminants.
- It is caused by a virus of the family paramyxoviridae and genus morbillivirus.
- It is closely related to other members of the genus, including the rinderpest virus, measles virus, and canine distemper virus.
- It is characterized by severe morbidity and mortality rates. The virus does not infect humans.
- Symptom includes oral necrosis, mucopurulent nasal and ocular discharges, cough, pneumonia, and diarrhea.

- Transmission can also occur indirectly through contact with infected objects (fomites) such as feed troughs, bedding etc.
- A short term infection due to fomites such as such as pasture and water troughs, feed and bedding Feeding in a group
- Sources of PPRV include secretions from the eyes, nose, and mouth of infected animals, as well as their faeces.
- Once introduced, the virus can infect up to 90 percent of an animal herd, and the disease kills anywhere from 30 to 70 percent of infected animals.
- More research is needed to understand its transmission in other species, such as camels and antelope
NOTE-
- PPR was first described in 1942 in Côte d’lvoire. Since then the disease has spread to large regions in Africa, the Middle East and Asia.
- Today, more than 70 countries have confirmed PPR within their orders, and many countries are at risk of the disease being introduced.
