Can it affect people?
No. FIV, also known as Feline AIDS only affects cats. 

How can FIV be contracted?
FIV virus is transmitted mainly through biting wounds from cat fights. The virus can also be transmitted from pregnant queens to kittens as well as through semen. Grooming or sharing common food/water bowls are less likely to spread the virus.
 
How can I know if my cat has FIV?
A simple and quick blood test can detect if the cat has been exposed to FIV. Once exposed to the virus, the cat will likely be infected for life. Cats that have been vaccinated against FIV will also be tested positive to FIV. There is no way of differentiating if the cat is positive to the infection or vaccination.
 
What are the signs of an infected FIV cat?
Similar to the Human AIDS virus, FIV infection generally does not cause illness at the early course of infection. Signs may appear as long as 6 years after being infected with FIV. The signs include severe gum infection, poor healing from wounds or illnesses, weight loss and inappetance. Eventually, widespread organ failure may lead to the cat’s passing.
 
Is there a treatment for FIV?
There is no cure for FIV although most opportunistic infections can be treated to maintain the cat in a relatively good health status for a while. The long term prospect of the cat is not good.
 
What should I do with a FIV positive cat?
An FIV infected cat should be restricted indoors to prevent it from getting into fights. It is important to be fair to other cats by ensuring that an FIV positive cat does not spread the virus.
