The percentage of domestic cats (‘client-owned’) with FIV (Feline immunodeficiency virus) various substantially depending on the country and the status of the cats. The variation is surprising to me. The differences may be due to the fact that sometimes domestic cats are stray cats and there is a big range of lifestyles of domestic cats which dictate the vulnerability of the cats to getting the virus.
The information below comes from studies which are listed at the base of the page.
The occurrence of FIV in naturally infected domestic cats by country:
- Germany 2-3.2% of cats depending on study
- Netherlands 2% of cats
- America 1-16%. Another study reports 2.5%
- Japan 44%
- UK 3% – 33%. One shelter study reports 3-11.5%
- Malaysia 12%
- Hungry 9.9%
- Brazil 5.84% – 14.7%
- Asia 0-22%
- Northern Europe 2-6%
- Southern Europe 10%
- Turkey (Istanbul) 22.3%
- Canada 5.5%
Infection rate depends on lifestyle, gender and health status. The virus damages cells in the immune system often white blood cells. Males are at least twice as likely to get it than females as they are in more fights where the infection occurs after a bite with the disease transmitted in the saliva.
