Sexually transmitted infections, preventions and treatments

Sexual Health Sexually transmitted infections, preventions and treatments page iconA sexually transmitted infection (STI) is a bacterial or viral infection that can be passed through unprotected sexual contact. Anyone can contract an STI, but there's no need to worry. Most infections are easy to detect and treat. Testing is free and confidential.

For more information about STIs, visit the NHS website.

What is PrEP?

PrEP, or 'pre-exposure prophylaxis,' is a medication taken by HIV-negative people to prevent them from catching HIV. If someone taking PrEP is exposed to HIV, the anti-HIV drugs in their body stop the virus from entering cells and replicating. 

Is PrEP effective? 

Research shows that PrEP is highly effective in preventing the transmission of HIV when taken correctly. While PrEP can prevent HIV infection, it does not protect against other sexually transmitted infections.

Is PrEP for everyone?

PrEP is likely to benefit people who are at high risk of HIV infection. For example: 

  • Men who have sex with other men (MSM)
  • People with partners from regions where the HIV rate is high
  • People with a HIV-positive partner who does not have an undetectable viral load
  • People who do not always use condoms during sex 

People who consistently use condoms correctly don't need PrEP. Those who know their partner is HIV-negative or has an undetectable viral load while on HIV treatment also don't need to use PrEP. 

What should I do if I want to start using PrEP? 

If you are interested in using PrEP, please make an appointment with any WISH clinic. 

During your initial assessment, you'll be asked about your sex life, medical history, and vaccination history. You'll need an HIV test to confirm you are HIV-negative. You will be tested for other STIs. Your kidney function will be checked, and a pregnancy test may be done if necessary.

Is PrEP different from PEP? 

Yes.

  • PrEP is different from PEP.
  • PEP (post-exposure prophylaxis) is a combination of HIV drugs taken for 28 days after possible exposure to HIV.
  • PrEP is taken regularly before sex to prevent HIV.
  • Both are used to prevent HIV infection.
