title: Update on feline calicivirus: new trends.
abstract: In addition to being important upper respiratory tract pathogens of cats, FCVs are increasingly reported as a cause of a highly contagious febrile hemorrhagic syndrome. Strains causing this syndrome are genetically different from the vaccine strain and other nonhemorrhagic FCV isolates. They apparently differ from one outbreak to another. The syndrome is characterized variably by fever; cutaneous edema and ulcerative dermatitis; upper respiratory tract signs; anorexia; occasionally icterus, vomiting, and diarrhea; and a mortality that approaches 50%. Adult cats tend to be more severely affected than kittens, and vaccination does not appear to have a significant protective effect. Rapid recognition of the disease through identification of clinical signs and appropriate testing, followed by strict institution of disinfection, isolation, and quarantine measures, are essential to prevent widespread mortality resulting from the infection.
