A drug that breaks down mucus, like bromhexine, also can help reduce congestion. He wants to know why some cats experience a short flu-like illness, while others develop a chronic gingivitis or the more severe life-threatening form of the disease. FCV-VSD is fatal in up to 60 percent of cats that develop the disease. Cats that develop FCV-VSD will have much more severe symptoms, including a high fever, swelling of the head and legs, as well as crusting sores and hair loss on the nose, eyes, ears and footpads. first the cat will have symptoms that look like a cold, with sneezing, nasal congestion, fever and sometimes drooling It is highly communicable in unvaccinated cats, and is commonly seen in multi-cat facilities, shelters, poorly ventilated households and breeding catteries. Like FHV-1, FCV commonly causes feline URTD, accounting for 10% to over 50% of cases. Cats should receive boosters every three years, unless they are in a high-risk, multi-cat environment, in which case they should be revaccinated annually. Approximately 10% of cats housed in small groups are infected, while up to 90% of those housed in more crowded conditions, such as in shelters and breeding catteries, may be infected. What is the difference between FCV and FHV? These symptoms can persist from five to 10 days in mild cases and up to six weeks in more severe ones. Visit our Research & Studies page to learn more. Studies in his lab have shown that these viruses can’t be identified based on their genetics, but there are detectable differences among the strains when they grow in cells in the lab. It is a member of the Caliciviridae family. Feline calicivirus (FCV), one such surrogate, survives well in the environment and is relatively resistant to chemical challenges (13, 14, 16, 28). While most of the droplets fall to the ground, contaminating the surface on which it lands, the virus can also survive on tiny dust particles or dander and survive for hours traveling throughout your facility until inhaled by another host. It is one of the two important viral causes of respiratory infection in cats, the other being Felid alphaherpesvirus 1. Even cats that have recovered from a calicivirus infection should receive boosters, because they may not be protected against other strains of the virus. Different strains of feline calicivirus cause different symptoms with varying severity including discharge from the eyes and nose, fever, sores in the mouth, loss of appetite, lethargy, and, in extreme cases, limping. A cat’s risk of exposure is higher in shelters, pet stores, and catteries, where 25 to 40 percent of cats may be carriers. Incorrect negative results are more likely if the cat is swabbed more than a week after the start of the infection. The … More … Parker’s research group has investigated different strains of the virus that cause outbreaks of FCV-VSD. It involves contact with the animal's fluids, such as feeders, toys and litter products. Transmission. Prevention Direct contact with infected cats. Feline calicivirus is a highly contagious virus that causes a mild to severe respiratory infection and oral disease in cats. Parker, associate professor of virology at the Baker Institute for Animal Health has worked with calicivirus for 15 years. Feline calicivirus (FCV) is a virus that infects domestic cats, causing a range of flu-like symptoms. Contact us to learn more about results achieved by PetAirapy UV systems in one air pass and why our UV products should be part of your infection control strategy. Samples (25 g) of soil (black earth soil, loamy soil, and sandy soil) were spiked with murine norovirus (MNV) and feline calicivirus (FCV), mixed with five different buffers and viral genetic material was extracted by 3 commercial kits. Feline Calicivirus(FCV) infection is a viral infection of the upper respiratory system in cats. If you have multiple cats and one or more are being treated for FCV, then you should quarantine the infected animals and clean food and water bowls, the litter box and other items that may be contaminated with the virus. Feline Calicivirus Transmission Feline Calicivirus is shed from infected cats primarily in discharges from the eyes, nose and mouth, and it can also be found in blood, urine and feces. Cats typically shed the virus for about two or three weeks after infection, but some cats become long-term carriers, and continue to shed the virus on and off for months. Several combination vaccines against FCV, feline herpesvirus type 1 and feline panleukopenia virus (the cause of feline distemper) are available, which can be given nasally or as an injection. Feline calicivirus is extremely common in shelters, causing a range of effects from subclinical or mild disease to Virulent Systemic Feline Calicivirus (VSFCV). It’s a common misconception that cats will never rid themselves of FCV once first infected. Feline calicivirus most often affects the lining of the mouth and the lungs. Parker is also looking into the finer details of how FCV gets inside feline cells, where it copies itself using the cell’s machinery. A severe form called virulent systemic feline calicivirus (VS-FCV) has been found in shelters or in environments where many cats are housed together. These viral strains cause isolated, rare outbreaks of severe systemic disease with up to 60% or higher mortality, although some infected cats may have mild clinical signs or no signs at all. Treatment Feline calicivirus is a common cause of URD. Feline calicivirus exists as a wide variety of strains, meaning a cat can get infected many times throughout its life, in a similar way to humans picking up a common cold time and again. Recent vaccination with a modified live strain of the virus can also cause a false positive result. This form is very contagious and can be fatal. The virus spreads through direct contact with the saliva, nasal mucus and eye discharge of infected cats and through aerosol droplets that spread when cats sneeze. The virus is readily transmitted between cats through: Direct contact – through contact with saliva, ocular or nasal secretions; Inhalation of sneeze droplets Feline calicivirus causes FCV, with the usual symptoms including: The virus must shape-shift to attach to a receptor molecule on the surface of cells, which allows it to gain entry. Symptoms and complications Fomite transmission is another very common means of spread for Calicivirus. In addition, food or water bowls contaminated with the virus may serve as a carrier of infection to healthy pets. The clinical course usually is 7–10 days. The following is not intended as a substitute for professional medical advice, diagnosis, or treatment for your pet. It is especially common in shelters and breeding colonies, and often infects young cats. Feline calicivirus (FCV) is a virus that is very common in the cat population. For more information and details for both pet care facilities and pet parents on how best to prevent the spread of infectious disease, visit our kennel cough page. Keep the nose and eyes of the cat clean and use vaporizers and saline nose drops to help clear the nasal passages. Most cats can recover at home, but severely affected cats may need intensive nursing care. Cause After the virus replicates there, it likely spreads through the bloodstream to other organs. The virus attacks the respiratory tract (nasal passages and lungs), the mouth (with ulceration of the tongue), the intestines and the musculoskeletal system. Transmission of Feline Calicivirus. The first known outbreak of FCV-VSD occurred in Northern California in 1998. Strains vary in the severity of the disease that they cause, with the majority causing only mild disease. All felids are apparently susceptible to feline calicivirus infection. Feline calicivirus (FCV) is a non-enveloped, single-stranded RNA virus with a spherical capsid that is studded with cup-shaped depressions (calici = “cup”) (Figure 23-1). This means that if your cat is near an infected cat, it is quite likely to catch the Calicivirus infection as well. Spread through the air. Transmission and Spread of Feline Calicivirus Infection Infection is attained by ingestion or inhalation of infectious virus present in saliva and excretion or secretions from infected cats . Owners may need to re-home carrier cats before disinfecting the home to protect the remaining animals from exposure. Objects that come in contact with a cat’s bodily fluids, such as food bowls, litter boxes or bedding, can also be a source of infection. Contact us about product information, pricing and a free consultation. According to Cornell University’s College of Medicine, currently there is no treatment to stop calicivirus, but supportive care can be offered while a cat’s immune system fights the infection. Meaning that despite infection, cats show no symptoms. ... Enclosures should be side by side rather than facing one another to prevent virus transmission via sneezing. Feline Calicivirus Feline calicivirus (FCV) is a highly contagious virus in cats, and one of the main causes of respiratory infection. Transmission of Feline Calicivirus Most cats become infected with the virus when they come in contact with contaminated surfaces such as food or water bowls.

Feline calicivirus (FCV), one such surrogate, survives well in the environment and is relatively resistant to chemical challenges (13, 14, 16, 28). Feline Calicivirus Infections – Transmission, Symptoms, Diagnosis, and Prevention by Cristina Vulpe PhD Feline calicivirus infections are caused by a virus that mostly affects the upper respiratory tract and oral cavity of cats. A cat’s symptoms will depend on the strain of FCV it contracts. This vaccine may offer some protection against outbreaks of FCV-VSD, but since the virulent strains that cause these outbreaks arise from different mutations in less aggressive strains, it is unknown how effective Calicivax™ will be against future outbreaks. This infec… Feline calicivirus (FCV) belongs to a large family of viruses named Caliciviridae, whose members infect a wide range of vertebrate animals, including rabbits, livestock, reptiles, birds and amphibians. Cleaning solutions that contain phenol, like Lysol, also are effective, but should not be used around cats because they cause irritation and are toxic. Contact us to learn more about results achieved by. Cats that receive the nasal vaccine may sneeze for four to seven days after vaccination. The most common form of transmission is through direct contact with nasal and eye discharge of infected cats. food bowls, water bowls, litter boxes etc). Most cats with feline calicivirus become silent carriers, shedding the virus continually. The most common route of infection occurs through objects or spaces the infected cat usually uses. Dr. John S.L. Most cats can recover at home, but severely affected cats may need intensive nursing care, including those that develop VS-FCV. Fortunately, it is quite rare for cats to succumb to FCV infection. The virus poses no threat to humans. Vaccination does not prevent infection but reduces severity of infection. Ask about air and surface sanitation protocols used to help stop or control the spread of FCV and other illnesses. What are the symptoms of feline calicivirus. If the cat is already older than 16 weeks, give two doses of the vaccine, three to four weeks apart. Natural transmission of these agents occurs through small droplets in the air (such as from a sneeze) and contaminated objects, which can be carried to a susceptible cat by a handler. Whenever you bring a new cat into the home, it is wise to isolate the animal from other cats in the household for one to two weeks while you watch for signs of disease. Cats that become carriers will continue to shed the virus in the home, even after they recover from the infection. After being exposed to FCV, the incubation period is two to 14 days before symptoms appear. There are many strains of FCV with varying ability to infect cats and varying severity of disease. It’s one of the most contagious and dangerous medical conditions that affect cats, and it is also known as cat flu. More virulent strains can cause serious systemic illness and death. Pet care facilities should have air purification systems and surface disinfection protocols in place. Its symptoms include nasal discharge, gingivitis and mouth ulcers. However, since FCV is primarily a respiratory pathogen and appears to be less acid tolerant than HNV, its relevance as a surrogate for HNV has been questioned by some investigators ( 11 ). Most cats develop an upper respiratory tract infection and in more severe cases, the virus travels into the lungs where it causes pneumonia. FCV can be transmitted through multiple routes. It can remain infectious for several days on different surface types, including stainless steel and plastic, at ambient temperatures (22 ±2 ° C). Failing to wipe down counters or thoroughly wash feeding dishes could cause animals in your care to develop this nasty ailment. Transmission Feline calicivirus is spread between cats through direct contact with the eyes or nose of an infected cat or contact with contaminated objects that an infected cat has sneezed on or touched, such as food and water bowls. A dilute bleach solution made up of one half cup of bleach per gallon of water is effective at killing the virus. Labs can also test tissue or serum samples.

However, since FCV is primarily a respiratory pathogen and appears to be less acid tolerant than HNV, its relevance as a surrogate for HNV has been questioned by some investigators . Cats with low immunity also are very susceptible to catching the feline calicivirus. Lab tests have also detected the virus in urine, feces and blood. Studies suggest that the nasal form of the vaccine leads to more rapid protection against the virus, which may be helpful in containing outbreaks in shelters. A vaccine called Calicivax™ is available that includes modified forms of a strain of FCV that causes FCV-VSD, and a typical strain of FCV. FCV occurs most commonly in multi-cat environments. These investigations into FCV not only give us a better understanding of this common feline infection, but can also help advance the study of similar caliciviruses, such as human norovirus. Vaccines against FCV are highly recommended.
