Sexually Transmitted Infections (STIs) and Sexually Transmitted Diseases (STDs) are conditions that are generally spread from one person to another through sexual contact. They can be caused by bacteria, viruses, or parasites, and can affect both men and women.

Individuals with STIs and STDs experience no symptoms at all, but if they do experience symptoms, they may include:
- Burning urination
- Sores or bumps on the genitals
- Discharge from the penis or vagina
- Pain during sex
- Vaginal bleeding
- Swollen or sore lymph nodes
- Fever
- And more.
Individuals who are sexually active are always at some risk of exposure to an STD or STI, though factors that may increase the chances of contracting one include having unprotected sex, having sex with multiple partners, having a history of STIs, being young, or injecting drugs (which is associated with HIV, and hepatitis B and C).
