Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) are caused by infections that you get when you've had sex without a condom. This section will break down what the different types are and what the symptoms are.


Bacterial vaginosis

Bacterial vaginosis (BV) generally affects women. It’s when the normal balance of bacteria in the vagina is disrupted by an increase of more ‘harmful’ bacteria.


Scabies is a very itchy, contagious skin infection caused by the scabies mite.

Pubic lice

Pubic lice are also known as ‘crabs’. Pubic lice are small parasites that dig underneath your skin, and feed on your blood.


Trichomoniasis is also known as ‘trich’. It’s an STD that affects both women and men, but women are more likely to have symptoms.

Hepatitis B

Hepatitis B is a contagious liver disease caused by hepatitis B virus (HBV) infection.

Water Warts

Water warts are caused by a virus called molluscum contagiosum. It’s a common viral infection that affects skin. If you become infected, your skin develops fluid-filled blisters.

Genital herpes

Genital herpes is an STD caused by 2 different types of herpes simplex virus (HSV). It looks like a cold sore or blister. While the virus is highly contagious, most people who have it don't get the cold sores or blisters.

Genital warts

Genital warts are caused by the human papillomavirus (HPV). It’s one of the most common STDs worldwide.


Syphilis is an STD caused by a bacterium called Treponema palliduium. It’s known as the ‘great imitator’ because its symptoms are often hard to distinguish from other STDs.


Gonorrhoea is caused by bacteria called Niesseria gonorrhoeae. It's very contagious. It can infect your throat, urethra (tube where urine comes from), vagina, and anus. 


Chlamydia is an STD caused by bacteria called Chlamydia trachomatis. Chlamydia can infect your urethra (the tube that leads from your bladder to where your pee comes out), vagina/cervix area, anus, or eyes.

Candida (yeast infection)

Candida is a fungal infection. It’s also known as yeast infection, Candidiasis, thrush, or genital Candidosis.


HIV is short for Human Immunodeficiency Virus, which causes AIDS. AIDS is short for Acquired Immune Deficiency Syndrome.
