Can you catch HIV from kissing?

No. The HIV virus can be spread through the exchange of bodily fluids, such as blood, semen and vaginal fluids. However, infectious HIV particles are unable to survive in saliva.

How HIV is spread

The most common way that HIV is spread is through sexual intercourse, including oral and anal sex.

The virus can also be spread through sharing needles, and it can be passed from an infected pregnant woman to her unborn baby. However, due to medical advances, steps can be taken to help reduce the likelihood of HIV being passed on to a baby.

For example, the risk of transmission can be reduced by:

  • giving antiretroviral medication to a mother and her newborn baby
  • giving birth by Caesarean section (where the baby is delivered through an incision that's made in the abdomen and womb)
  • not breastfeeding

You can't catch HIV from:

  • kissing
  • being sneezed on by someone with HIV
  • sharing baths, towels or cutlery with someone with HIV
  • swimming in a pool that has been used by someone with HIV
  • sitting on a toilet seat that someone with HIV has previously sat on
