Researchers discover bats as reservoir of infections

Measles, mumps, pneumonia, influenza and encephalitis in man, Carré's disease in dogs, Ovine Rinderpest (PPR)… all of these diseases are caused by viruses from the same family: Paramyxoviridae.

This family of highly diverse pathogens affects all animals, from canines to fowl, cattle and humans.
