There are lots of myths about how you get HIV, but the virus is not easily passed on.
In order to be passed on, HIV has to be present in detectable levels in the blood, semen, vaginal fluids or breast milk - usually when a person is not on effective treatment or has not yet been diagnosed.
Something you may not realise is that if someone with HIV is on effective treatment and has an undetectable viral load, they cannot pass on HIV. It can take up to six months on treatment for some people to become undetectable.
Here are some common questions about HIV:
Can you get HIV from kissing or shaking hands?
There’s NO risk from casual social contact such as:
- shaking hands
The virus cannot get through unbroken skin and is not spread in saliva.
It's also safe to give mouth-to-mouth resuscitation (giving 'the kiss of life').
Can you get HIV from coughs, sneezes or other bodily fluids?
There’s NO risk from coughing or sneezing. HIV does not travel in the air.
The virus is also NOT passed on in:
- saliva (and spitting)
- urine or faeces.
You can't get HIV from blood, sexual fluids or breast milk when the person with HIV is on effective treatment and has an undetectable viral load.
Can you get HIV from toilet seats or sharing cups and plates?
No, HIV cannot be caught from:
- toilet seats
- swimming pools
- hot tubs
It's safe to share objects someone with HIV has touched or used to eat or drink from.
Can you get HIV from animals or insects?
HIV is only found in humans. It cannot be spread by insect bites (including from mosquitoes).
Can you get HIV from giving or receiving blood?
No one gets HIV from giving blood.
There is also no need to worry about receiving blood as in the UK blood and blood products are screened to make sure they don’t have HIV.

Can you ‘catch’ AIDS?
You can ‘catch’ HIV, the virus that can lead to AIDS but you cannot ‘catch’ AIDS itself.
AIDS stands for 'acquired immune deficiency syndrome' and is a name for a collection of illnesses people with HIV can get if they don’t receive treatment. Generally people who get HIV these days will not go on to get AIDS so long as they test and start treatment in time.
In order to pass on HIV, the person's viral load must be detectable. So if they have an undetectable viral load and are on effective treatment, they cannot pass on HIV. It can take up to six months from starting treatment to become undetectable.
