Episotological monitoring of coronavirus enteritis in cats

Feline coronavirus enteritis is widespread throughout the world and is known to cause disease in both domestic and wild feline species. In some individuals, the viral disease is a consequence of infectious peritonitis. To study the prevalence of feline coronavirus enteritis in the world, a literature analysis was performed using resources such as the Google Scholar website, the scientific portal ResearchGate, the official website of the U.S. government, the National Center for Biotechnology Information, and the international journal Sciencedirect. The epizootiological characteristics of infectious peritonitis in cats were studied taking into account the nosological profile, breeds, age, and seasonality. Outpatient admission records for the years 2022 and 2023 were used. We analyzed 535 cats for infectious diseases during this period. It was found that panleukopenia was diagnosed in 200 cats (37%) during this period, followed by rhinotracheitis (herpesvirus infection) in 137 (25.6%) animals. Calicivirus infection was the third most common. 90 (17%) cats became ill with it. 15 cats fell ill with feline coronavirus enteritis (infectious peritonitis), which is 3%. In the structure of viral diseases of cats coronavirus enteritis is in: Australia - 34-54%, Croatia - 42%, Czech Republic - 63%, Galapagos and Falkland Islands - 0%, France 17%, Germany - 62%, Greece - 10-19%, Italy - 19-51%, Great Britain - 20-65%, USA - 56%, China - 12.7%, Japan - 31-67%, Korea - 7-14%, Malaysia - 70-90%. Coronavirus enteritis in cats is not very common in the nosological profile of infectious diseases in Ukraine and according to our researches it is 3%. Panleukopenia was the first disease in 200 cats (37%), followed by rhinotracheitis (herpesvirus infection) in 137 (25.6%) animals. Calicivirus infection was the third most common. 90 (17%) cats had this infection. We found that 7 breeds of cats (British Shorthair, Sphynx, Scottish Fold, Devon Rex, Metis, Bengal, Maine Coon) suffered from infectious peritonitis. At the same time, cats of the Maine Coon and Metis breeds got sick the most. It was found that the peak of clinical manifestation of the disease is observed in October and November. The disease is difficult to treat and has a high mortality rate of 37.5%. The disease was more severe in cats with dry form. They were twice as likely to die as cats with a wet form. Cats between 3 and 6 months of age were most affected by infectious peritonitis, accounting for 33.34% of the age structure. The disease was also more frequent in cats aged 9 months to 2 years
