FIV – the disease course
The disease progresses in 5 stages.
In phase 1, the acute phase, slight symptoms may occur after about 4 weeks after infection. This is not necessary. What can be observed are fever, swollen lymph nodes, diarrhea, skin or intestinal infection. This phase can take up to 4 months.
In phase 2, the asymptomatic phase, the cat shows no symptoms of disease. This period can take a number of years, sometimes even longer than 5 years.
In phase 3, vague complaints are seen: recurrent fever, eye inflammation, loss of appetite, weight loss, anemia, swelling of the lymph nodes. In itself no serious complaints, so that not every owner will go to the vet.
Phase 4,the AIDS-related complex, is the stage where most cats get more chronic complaints, such as swollen lymph nodes, sneezing, gum disease, eye inflammation, weight loss, diarrhea, anemia, exhaustion, skin conditions, inflammation of the airways. These symptoms become worse over a period of a few months to years.
Phase 5 is the AIDS stage. The defense no longer functions. There are now developing mouth, nose, eye, skin and intestinal infections, pneumonia, anemia and fever. The cat is losing a lot of weight. Sometimes you also see neurological symptoms. Sometimes Less common symptoms are seen at this stage are dementia, rolling movements of the head, uncleanliness, hiding and aggressive neurological symptoms. These last symptoms are seen more often nowadays. The animals at this stage have a prognosis of a few months.
