Sexually transmitted infections

So you caught something, huh?

Sexually transmitted infections (STIs) are those that are passed on through sexual contact, through genital contact or body fluids, including blood. Some vaginal afflictions make it much easier for STIs to infect you, especially bacterial vaginosis (BV).

STIs need to be treated immediately with antibiotics, or in the case of more serious, lifelong infections, with antivirals, immunosuppressants or other herbal, medical or physical therapies.

If you suspect you have an STI, see your doctor or local sexual health clinic immediately to be tested and treated. Don’t have unprotected sex with anyone in the meantime, since you could pass it on.
