Peste Des Petits Ruminants: What Sheep Farmers Need To Know

Oct 09, 2026

 

Peste des petits ruminants (PPR) is one of the diseases that can quickly turn into a serious problem for sheep and goat farms. Often called sheep and goat plague, it is caused by peste des petits ruminants virus (PPRV), a virus in the Morbillivirus genus. The disease affects small ruminants and can spread quickly when animals are kept close together.

 

The first signs are not always easy to distinguish from other illnesses. An affected sheep may develop a fever, stop eating and appear unusually quiet. Discharge from the eyes and nose may follow. In more severe cases, sores develop inside the mouth, breathing becomes difficult and diarrhea leads to dehydration. Some animals deteriorate rapidly, and mortality can be high during severe outbreaks.

 

PPR is particularly difficult for farms because one sick animal can signal a wider problem within the flock. Shared feeding areas, close contact and the movement of animals between farms can all contribute to transmission. An outbreak may mean more than veterinary treatment and animal losses; it can also disrupt breeding plans, sales and the daily management of the farm.

 

The symptoms alone are not enough to confirm PPR. Other diseases can cause fever, oral lesions and diarrhea, so veterinary assessment and appropriate laboratory testing are important when the disease is suspected. Vaccination and farm biosecurity remain key parts of prevention, especially in areas where PPR is known to occur.

 

Where Does Antibody Testing Fit In?

The Ovine Peste des Petits Ruminants Virus Antibody Test is used to detect antibodies against PPRV in sheep. It can be useful for flock serological surveillance and for assessing antibody responses after vaccination. However, antibodies do not automatically mean that an animal currently has an active infection. The result needs to be considered alongside the animal's vaccination history and the reason for testing.

 

PPR control depends on recognizing suspicious signs early, reporting suspected outbreaks and following local veterinary guidance. For sheep farmers, understanding how the disease spreads and keeping track of flock health are practical steps toward reducing its impact.
