How genital warts are passed on
The genital warts virus can be passed on whether or not there are visible warts.
Many people with the virus don't have symptoms but can still pass it on. If you have genital warts, your current sexual partners should get tested as they may have warts and not know it.
If symptoms do appear, it can happen over a year after infection.
You can get genital warts from:
- skin-to-skin contact, including vaginal and anal sex
- sharing sex toys
- rarely, oral sex
The virus can also be passed to a baby from the mother at birth, but this is rare.
You can't get genital warts from:
- kissing
- things like towels, cutlery, cups or toilet seats
