FIV - Immunodeficiency Virus in Cats: A Comprehensive View
Contents
FIV or Feline Immunodeficiency Virus, also known colloquially as feline AIDS, is a specific disease in cats that has parallels to the human AIDS disease. It cannot be transmitted to other animals or humans.
Transmission and risk groups of feline AIDS
FIV is primarily transmitted through direct contact with infected body fluids. This is particularly common in fights between cats that result in bites. Other potential routes of transmission include blood transfusions, sexual contact, and transmission from infected mother cats to their puppies. However, the ability of the FIV virus to survive outside the body is extremely limited, minimizing the likelihood of infection through shared food, water, or grooming.
Unneutered male cats are particularly at risk because they are more often involved in fights. Neutered male and female cats, on the other hand, have a lower risk.
Course of infection and symptoms
Once transmitted, the FIV virus can cause fever and swelling of the lymph nodes, which are often attributed to the bite rather than the infection. The virus penetrates certain immune cells and is integrated into the cell's own DNA, whereupon these cells produce FIV viruses and infect new immune cells.
The infection typically goes through several phases. The initial infection is followed by an asymptomatic phase that can last several years. During this phase the cats show no symptoms of illness. This is followed by a phase of non-specific symptoms and increased susceptibility to infections. In the final phase, which has similarities to AIDS, infected animals exhibit more severe symptoms, develop tumors, exhibit neurological symptoms or altered behavior.
How does cat AIDS manifest itself?
FIV, or Feline Immunodeficiency Virus, manifests itself in several phases, with each phase characterized by different symptoms:
Acute phase : This occurs in the first few weeks after infection. Typical symptoms can include fever, swollen lymph nodes and loss of appetite. However, many cats do not show any obvious symptoms during this phase.
Asymptomatic phase : The acute phase is followed by an asymptomatic phase that can last years to decades. During this phase, the cat shows no obvious symptoms of the disease, although the virus remains active.
Symptomatic phase : Eventually, cats may enter the symptomatic phase of FIV infection. This phase is characterized by a series of symptoms that indicate a general decline in health. These may include: weight loss, chronic mouth and gum infections, skin infections, urinary tract infections, chronic diarrhea and behavioral changes. More serious illnesses such as various forms of cancer and blood abnormalities can also occur during this phase.
It is important to note that not all cats infected with FIV reach the symptomatic phase. Many FIV-positive cats live for years without any visible signs of the disease. Therefore, regular veterinary examination is crucial for FIV-positive cats.
Diagnosis and treatment of feline AIDS
Diagnosis of feline AIDS is usually made through a blood test that detects either the virus itself or the antibodies produced by the body against the virus. If the result is positive, confirmation should always be made using another test method or a second antibody detection.
Treatment focuses primarily on preventing and controlling secondary infections. There is no cure for FIV, and infected cats shed the virus for life. The main goal of the treatment is to keep the cat's environment as germ-free and stress-free as possible. Antiviral medications can slow the progression of the infection but do not provide a cure.
Early detection and diagnostics
Early detection of FIV is a crucial step in ensuring a cat's long-term well-being. Regular veterinary and testing are essential to monitoring a cat's health and detecting any health problems early.
Diagnosis of FIV is based primarily on antibody tests, which detect antibodies against the virus in the cat's blood. This test is easy to perform and usually produces quick results. However, it is important to note that this test cannot distinguish between antibodies produced by infection and antibodies produced by vaccination. Therefore, a positive test result cannot always be considered definitive proof of FIV infection.
In such cases, PCR (polymerase chain reaction) can be performed to directly detect the presence of the virus in the cat's blood. This test is more specific and accurate, but is also more expensive and requires special laboratory equipment.
It should be noted that detecting FIV in a cat does not automatically mean that the cat is or will become ill. Many FIV-positive cats live long, healthy lives with little to no symptoms.
Treatment strategies for FIV-positive cats
Although there is currently no cure for FIV, there are several strategies for treating and managing FIV-positive cats. Appropriate treatment can help slow the progression of the disease and maintain the cat's quality of life.
Treatment for FIV focuses primarily on controlling symptoms and treating secondary infections. Antibiotics can be used to treat bacterial infections, while antiviral medications can help reduce viral load and relieve symptoms.
In some cases, the use of medications to strengthen the immune system may be useful. However, this is a controversial topic because such drugs can activate the immune system, which then produces more cells that the virus attacks.
Living with FIV-positive cats
With proper care and handling, FIV-positive cats can live long, fulfilling lives. It is important to have your cat examined by a veterinarian regularly to identify and treat possible health problems early.
While FIV-positive cats can usually live with other cats without infecting them, aggressive cats that are prone to bites should be kept separately. It is also important to keep FIV-positive cats indoors to minimize the risk of transmission to other cats.
Cats with feline AIDS require a lot of love, care and attention to ensure their well-being. With proper care and handling, they can live full and happy lives.

Survival and quality of life of cats with feline AIDS
Although FIV is a serious disease, cats infected with the virus can live long and happy lives with proper care and management. It is not uncommon for FIV-positive cats to live to a normal feline age, with their quality of life depending on their overall health, lifestyle and environment.
Above all, it is important to emphasize that FIV is not an immediately fatal disease. Cats can live symptom-free for many years before showing signs of immune deficiency. When such symptoms occur, they can often be well managed with appropriate support and care.
Caring for Cats with AIDS
Cats with AIDS require careful monitoring and care to maintain their health and slow disease progression. Regular veterinary examinations are essential to detect changes in health and treat them promptly. Because FIV-positive cats have weakened immune systems, they are more susceptible to infections and diseases that healthy cats can easily fight off.
The risk of secondary infections can be minimized through careful hygiene, good management and avoidance of stressful situations. It is advisable to keep FIV-positive cats as domestic cats in order to minimize contact with potentially disease-carrying animals.
It is also important to consider diet. A balanced diet can strengthen the immune system and improve the cat's overall health. In some cases, the veterinarian may recommend supplements to meet specific nutritional needs.
Vaccination and prevention
There is a vaccination against AIDS, but its use is controversial. The vaccination is not 100% protective and can produce false-positive test results because it produces antibodies to the virus that cannot be distinguished in the test from the antibodies produced by infected cats.
The best prevention is therefore to avoid risky behavior. These include fighting, contact with unfamiliar or infected cats, and sharing food bowls or litter boxes with infected animals. Domestic cats should be tested for FIV before coming into contact with other cats.
It should be noted that each cat is unique and requires individual care and management. The needs of an FIV-positive cat can change over time, and it is important to remain flexible and adapt to the cat's specific needs.
