Epidemiological status of felid herpesvirus type-1 and feline calicivirus infections in Brazil

Feline calicivirus (FCV) and felid herpesvirus type-1 (FeHV-1) are the main infectious agents of domestic and wild felines worldwide. The FCV and FeHV-1 viruses were isolated in Brazil in 1988 and 2012, respectively. Serology surveys were performed among domestic feline in the State of Rio Grande do Sul and among wild felines in central Brazilian States. Felines with acute or chronic infections may become carriers for both viruses and, viral transmission occurs mainly by ocular and nasal secretions. In addition, FCV may be transmitted by oropharyngeal secretion and fomites. The clinical signs commonly observed in cats are fever, sneezing, coughing and nasal and ocular discharge; however, oral lesions are restricted to FCV infection. A systemic syndrome showing hemorrhagic lesions, alopecia, facial edema and jaundice has been associated with FCV. Attenuated as well as inactivated vaccines against FCV and FeHV-1 were developed in the middle 1970s, and they are effective at reducing the presentation/development of the diseases, but they are not capable of eliminating the persistence of FCV and FeHV-1. This article presents a brief review of the main aspects of the FCV and FeHV-1 infections, with an emphasis in the current situation on the domestic feline population from Brazil.
