Teenage Health



What are they?

STI's, sexually transmitted diseases, STD's are diseases passed on through bodily fluids like saliva, blood and sexual fluids (e.g. sperm). We get and STI by having sex (influding oral sex) with someone who is infected.  All are unpleasant and can cause lasting damage but most are treatable and preventable.

How do I make sure I do not get an STI?

Use a condom every time you have sex.  This is the best protection we have.  Condoms are little latex life savers!

How will I know if I have caught an STI?

You may not know you have an STI and this means that you or your partner might be infected also and know nothing about it.  The best way to be sure is to come and see the doctor or nurse or visit your local sexual health clinic to rule out any infections.  Sometimes it is necessary to take a swab or blood test or urine.
