Feline coronavirus (FCoV) is a virus that is infectious to cats worldwide.
It has two different forms; the FECV (feline enteric coronavirus) that infects the intestines and the FIPV (feline infectious peritonitis virus) that causes the disease feline infectious peritonitis (FIP).
Feline coronavirus is typically shed in feces by healthy cats and transmitted by the fecal-oral route to other cats.
The virus is insignificant until mutations cause the virus to be transformed from FECV to FIPV. FIPV causes feline infectious peritonitis, for which treatment is generally symptomatic and palliative only.
