How long does a cat get sick with calicivirus? - briefly
The duration of illness in cats infected with calicivirus can vary significantly. While some cats may recover within a week or two, others may exhibit symptoms for several months, particularly if they develop chronic stomatitis as a result of the infection.
How long does a cat get sick with calicivirus? - in detail
The duration of illness in cats infected with calicivirus can vary significantly depending on several factors, including the cat's age, overall health, and the specific strain of the virus. Calicivirus is one of the most common pathogens affecting felines, known for causing upper respiratory tract infections.
In general, the acute phase of calicivirus infection in cats typically lasts from 7 to 14 days. During this period, the cat may exhibit various symptoms such as sneezing, nasal discharge, conjunctivitis (red and inflamed eyes), oral ulcers, and sometimes even pneumonia. The severity of these symptoms can range from mild to severe, with some cats showing minimal signs while others become quite ill.
However, it is important to note that calicivirus infections are not always acute. In many cases, the virus can persist in the cat's body for extended periods, sometimes even lifelong. During this chronic phase, the cat may not show any overt symptoms but can still shed the virus intermittently. This means that even if a cat appears healthy, it can potentially spread the infection to other cats through contact with respiratory secretions or saliva.
Furthermore, some cats may develop chronic gingivitis and stomatitis as a result of calicivirus infection. These conditions can cause persistent oral pain and inflammation, which may require long-term management and treatment.
The immune system's response also plays a crucial role in the duration of illness. Younger cats or those with compromised immune systems may experience more prolonged symptoms compared to healthy adult cats. Additionally, secondary bacterial infections can complicate the course of calicivirus infection, leading to a longer recovery time.
In summary, while the acute phase of calicivirus infection in cats typically lasts from 7 to 14 days, the virus can persist in the cat's body for much longer periods, potentially causing chronic issues and allowing for intermittent shedding and transmission of the virus.
