Feline panleukopenia virus (FPLV) is a species of parvovirus that can infect all wild and domestic members of the felid (cat) family worldwide. It is a highly contagious, severe infection that causes gastrointestinal, immune system, and nervous system disease. (“Panleukopenia” means a decrease in the number of white blood cells.)
It has been thought to be single variant of Carnivore protoparvovirus (CPV 1), however, it has been confirmed that a feline panleukopenia illness can be caused by CPV 2a, 2b, and 2c.
FPLV is commonly referred to as:feline infectious enteritis virus (FIE) feline parvovirus (FPV or FP or "feline parvo") feline parvoviral enteritis
It is sometimes confusingly referred to as “cat plague” and “feline distemper."
In addition to members of the felid family, it can also affect some members of related families (e.g. raccoon, mink).
