Rabies in cats
- Occurrence: rarer
- Location of illness: General/Whole body
Rabies is a viral infectious disease that affects the central nervous system of mammals, including cats. It is mainly transmitted through the bite of an infected animal and is almost always fatal once symptoms appear.
The most important facts at a glance
Rabies in cats is caused by the rabies virus, which is transmitted through the saliva of infected animals, often through bites. The virus travels through the nerves to the brain and causes severe inflammation. Symptoms include fever, behavioral changes, seizures, and respiratory distress. A definitive diagnosis is difficult because symptoms resemble other neurological diseases. After death, the disease can be confirmed by tests on brain tissue. Rabies is almost always fatal once symptoms appear, which is why the focus is on prevention. Cats should be vaccinated regularly to minimize the risk. Prevention also includes minimizing contact with wildlife and controlling stray cat populations. Research focuses on improving vaccines and developing antiviral drugs to stop the spread of the disease. New diagnostic techniques and gene therapy approaches could help to better control rabies in the future. Overall, advances in research are promising to prevent the spread of rabies in pets and in the wild.
Causes
Rabies is caused by the rabies virus, an RNA virus of the genus Lyssavirus. The virus is transmitted through the saliva of infected animals, usually through bites. After transmission, the virus migrates via peripheral nerves to the brain, where it causes acute encephalitis.
The virus initially multiplies at the entry site, often in the muscles, before entering the peripheral nervous system. From there, it travels along the nerve pathways to the central nervous system. This migration can take several days to months, which explains the incubation period.
One of the special features of rabies is its zoonotic nature, meaning that it can be transmitted from animals to humans. Common carriers of the virus are wild animals such as foxes, raccoons, bats, and occasionally domestic animals such as dogs and cats.
Symptoms
The first symptoms in cats can be nonspecific and include flu-like symptoms, which makes diagnosis difficult. These include fever, loss of appetite, and exhaustion. This phase is called the prodromal phase.
As it progresses, cats show neurological symptoms. These can manifest as behavioral changes such as aggressiveness, extreme startle response / jumpiness, or disorientation. Cats may also show excessive salivation, indicating difficulty swallowing and seizures.
In the paralytic phase, which occurs shortly before death, paralysis can occur, spreading from the hind legs forward. Respiratory distress and convulsions are also common and ultimately lead to the death of the infected cat.
Diagnosis
A definitive diagnosis of rabies in a living cat is difficult because the symptoms can resemble other neurological diseases. Therefore, the diagnosis relies on a combination of clinical signs, medical history, and exclusion of other diseases.
After death, the virus can be confirmed by direct detection of viral antigens in brain tissue using a direct fluorescent antibody test (dFA). These tests require special laboratory techniques and are usually performed in specialized laboratories.
Since rabies is a reportable disease, suspected cases should be reported to health authorities immediately to initiate further containment and prevention measures.
Therapy
Unfortunately, there is no effective treatment for cats that show symptoms of rabies. Once the clinical symptoms appear, the disease is almost always fatal. The focus is therefore on prevention and protecting uninfected animals.
In cases where a rabies infection is suspected, the affected cat is usually quarantined to prevent the spread of the disease. Euthanasia may be considered to end the animal’s suffering.
For domestic cats that may have come into contact with rabies but are not yet showing symptoms, post-exposure prophylaxis in the form of vaccinations may be considered, but this is less established in animals than in humans.
Prognosis and follow-up care
The prognosis for a cat infected with rabies and showing symptoms is extremely poor. The course of the disease is usually rapid and ends fatally within a few days of the onset of the first symptoms.
Since there is no cure, the only effective protection is prevention through vaccination and avoiding contact with potentially infected animals. Strict adherence to vaccination schedules is crucial to minimize the risk of rabies infection in pets.
Prevention
The most effective measure to prevent rabies in cats is regular vaccination. Cats should be vaccinated against rabies from about three months of age, followed by booster vaccinations according to the veterinarian’s recommendations. Vaccinations are not only a protection for the cat itself, but also for the people around them.
In addition, it is important to minimize the cat’s contact with wild animals that could potentially transmit rabies. Keep your cat indoors if possible, or supervise it outdoors to avoid contact with potentially infected animals.
Another important aspect of prevention is the control and containment of stray cat populations, as they may be at higher risk of rabies infections. Community-based programs for neutering and vaccinating strays can help reduce the spread of rabies.
In the event of a bite or scratch caused by a potentially rabid animal, a veterinarian should be consulted immediately. Rapid action and adherence to precautions are crucial to minimize the risk of rabies transmission.
Outlook on current research
Rabies research has made significant progress in recent years, particularly in the development of new vaccines and treatments. Much of the research focuses on improving prevention measures to stop the spread of the disease in both wildlife and domestic animals. Modern vaccines have become safer and more effective, and there are increasing efforts to increase vaccination rates worldwide to eliminate rabies in line with the “Zero by 30” initiative of the WHO.
Another important research focus is the development of antiviral drugs that can be administered after infection. While there is currently no cure for rabies, scientists are working to inhibit virus replication and alleviate symptoms. This research could ultimately lead to therapeutic options that slow or stop the progression of the disease in infected animals.
Genetic research has also provided new insights into the rabies virus. By analyzing the genetic sequences of different virus strains, researchers can better understand how the virus spreads and how it changes over time. This can lead to more targeted vaccination strategies and help predict and prevent outbreaks.
In addition, work is being done to improve diagnostic techniques. Faster and more accurate tests can enable early detection of rabies, which is particularly important to prevent spread in densely populated areas. New methods of molecular diagnostics could help identify infected animals more quickly and efficiently.
Another innovative approach is the use of gene therapy techniques to treat rabies. By specifically modifying genes that affect the immune system, researchers hope to strengthen the body’s own defenses against the rabies virus. Although this technology is still in its infancy, it could play a crucial role in the treatment of rabies in the future.
In summary, research on rabies in cats and other animals is a dynamic and promising field. Advances in vaccine development, diagnostics, and therapy offer hope for effective control and possibly even eradication of this deadly disease in the future.
