A liver infection that can be spread by blood-to-blood and sexual contact. Often no symptoms appear however can include jaundice, fatigue and nausea. Vaccination for Hepatitis B is available.
A liver illness that can be spread by blood-to-blood contact. Similar to Hepatitis B, there are often no symptoms. No vaccine is available for Hepatitis C.
Human Immunodeficiency Virus is a virus that attacks the body’s immune system. HIV can be transmitted by bodily fluids such as blood and semen during sex. There is currently no cure or vaccine for HIV.
Someone who does not have HIV.
Someone who is living with HIV.
Blood test commonly used during sexual health check-ups to detect antibodies to HIV. It is also called a HIV antibody test. See also rapid HIV test.
Dislike or prejudice against people who identify as homosexual or transgender.
Human Papillomavirus is a common STI that can cause genital warts and a range of cancers. It is spread during sexual contact and presents no symptoms. Vaccination for HPV is available.

Pre-exposure prophylaxis is a strategy whereby an HIV negative person takes HIV drugs in order to prevent acquiring HIV.
People living with HIV.
Tiny insects that live in coarse body hair such as pubic hair, armpits and facial hair. They are typically transmitted through sexual contact and cause itching and open sores. Treatment involves a cream/lotion.

A relationship where one individual has HIV and the other does not.
