Jot down a few questions to make the most of your conversation.
Can HIV be passed on through casual contact?
No, HIV cannot be transmitted through everyday casual contact. This includes hugging, shaking hands, sharing a room, or sitting next to someone who has HIV.
You also cannot catch HIV from saliva, sweat, tears, or urine in normal social situations. The virus does not spread through touching skin, sharing food, or using the same toilet.
How HIV is actually transmitted
HIV is passed on through certain body fluids, including blood, semen, vaginal fluid, rectal fluid, and breast milk. For transmission to happen, these fluids must enter the bloodstream or come into contact with vulnerable tissue.
This usually happens through unprotected sex, sharing needles or injecting equipment, or from mother to baby during pregnancy, birth, or breastfeeding. In the UK, these are the main routes of transmission.
Myths about casual contact
Many people worry about catching HIV from items like cups, cutlery, towels, or bedding. There is no evidence that HIV spreads this way in normal everyday use.
HIV does not live for long outside the body, and it is easily damaged by air and changes in temperature. That means it is not spread by touching surfaces, using public transport, or being around someone with HIV.
What about kissing, biting, or first aid?
Closed-mouth kissing is not a risk. Deep kissing is also very unlikely to transmit HIV unless both people have significant bleeding in the mouth, which is rare.
Human bites are not usually a route of transmission either, unless there is blood involved and the bite is severe. Giving first aid to someone with HIV is safe, especially if you use basic precautions such as gloves when dealing with blood.
Living and working with someone who has HIV
You can safely live, work, study, and socialise with someone who has HIV. Everyday contact does not put you at risk, and there is no need to avoid physical closeness.
People with HIV can lead healthy lives with effective treatment. In fact, someone who takes HIV medication and has an undetectable viral load cannot pass the virus on through sex, known as U=U.
When to get tested or seek advice
If you think you may have had a real exposure to HIV, it is important to get tested. This includes unprotected sex, a broken condom with a partner whose status is unknown, or sharing needles.
In the UK, you can get tested through your GP, sexual health clinic, or some pharmacies and home testing services. If you are worried after a recent risk, seek advice as soon as possible, because emergency treatment may be available.
