Pinpointing key risk factors of transmission of PPRV, a virus that produces a highly infectious and often fatal disease in sheep and goats, could improve vaccination campaigns to control the virus. A new study by an international team including Penn State researchers found that an animal's age does not affect PPRV transmission risk, but how those animals are managed plays an important role.
