How often is coronavirus found in cats? - briefly

The prevalence of coronavirus infections among cats is relatively low. While some studies have detected the virus in a small percentage of sampled felines, it is not widespread and does not typically cause severe disease in cats.

How often is coronavirus found in cats? - in detail

The prevalence of coronaviruses among cats, particularly feline infectious peritonitis virus (FIPV), is a subject of ongoing study and interest. FIPV is a mutated form of the common feline enteric coronavirus (FECV) that affects domestic cats worldwide. While it's difficult to provide an exact percentage due to regional variations and differences in study methodologies, several epidemiological studies offer valuable insights into the frequency of coronavirus infection in cats.

In general population surveys, the prevalence of FECV can be quite high, with some studies reporting rates as high as 30-40% among healthy cats. However, the incidence of FIP, which is caused by a mutation of FECV, is much lower. Estimates suggest that only about 5-10% of cats exposed to FECV will develop FIP. This discrepancy highlights the complex nature of coronavirus infections in felines and underscores the importance of understanding the factors that contribute to the development of FIP.

Several risk factors have been identified for the progression from FECV infection to FIP. These include young age, overcrowding, poor sanitation, and a compromised immune system. Multi-cat households and catteries are particularly at risk due to the higher likelihood of viral transmission and shedding among cats in close proximity.

Despite these risks, it is important to note that many cats infected with FECV do not develop clinical disease. The virus can persist in a cat's body for extended periods without causing symptoms, making detection challenging without specialized testing. Regular veterinary care and monitoring are crucial for early identification of potential issues and implementing preventative measures.

In summary, while the prevalence of coronavirus infection among cats is significant, the incidence of FIP remains relatively low. Understanding the risk factors and maintaining good hygiene practices can help mitigate the spread of these viruses in feline populations.
