Pubic lice (crab lice or ‘crabs’) are small, flat, light-brown parasites that cling to body hair. They’re easily transmitted through direct skin-to-skin contact during sex. They can also be spread by contact with towels, undergarments and bedding used by an infected person. Pubic lice can cause small red areas, sores, and itching.

Tinea is a common fungal skin condition. It can affect warm, moist areas, such as skin folds e.g. between toes, groin and under breasts.

Syphilis is caused by bacteria and is contagious in the early stages of transmission. Without treatment, it can cause irreversible damage to the brain, nerves and body tissues.

Trichomoniasis (trich for short) is a protozoan infection that causes inflammation of genitals.
