Study Notes
Sexually Transmitted Infections (STIs)
Definition and Prevalence
- Sexually transmitted infections (STIs) are infections that are spread through sexual contact with an infected person
- Also known as sexually transmitted diseases (STDs)
- Affect people of all ages, genders, and backgrounds
- Estimated 1 in 5 people in the US have an STI
Types of STIs
-
Bacterial STIs:
- Chlamydia
- Gonorrhea
- Syphilis
- Chancroid
-
Viral STIs:
- Human Immunodeficiency Virus (HIV)
- Herpes Simplex Virus (HSV)
- Human Papillomavirus (HPV)
- Hepatitis B
-
Parasitic STIs:
- Pubic lice (crabs)
- Scabies
Causes and Risk Factors
- Unprotected sex (vaginal, anal, or oral)
- Multiple sexual partners
- Prior history of STIs
- Sharing of sex toys
- Intravenous drug use
- Mother-to-child transmission during pregnancy, childbirth, or breastfeeding
Symptoms and Diagnosis
- Many STIs are asymptomatic, making it difficult to detect without testing
- Common symptoms:
- Pain or burning during urination
- Abnormal discharge
- Sores or lesions
- Itching or burning in the genital area
- Diagnosis through:
- Physical examination
- Laboratory tests (e.g., urine, blood, or swab samples)
- Imaging tests (e.g., ultrasound, CT scan)
Treatment and Prevention
- Bacterial STIs: treated with antibiotics
- Viral STIs: managed with antiviral medications, but not cured
- Parasitic STIs: treated with medicated creams or shampoos
- Prevention through:
- Safe sex practices (e.g., using condoms, dental dams)
- Regular testing and screening
- Vaccination (e.g., HPV, Hepatitis B)
- Avoiding sharing of sex toys and personal items

Parasitic STIs:
- Pubic lice (crabs)
- Scabies
Causes and Risk Factors
- Unprotected sex (vaginal, anal, or oral) increases risk of STI transmission
- Multiple sexual partners increase the risk of STI transmission
- Prior history of STIs increases the risk of future infections
- Sharing of sex toys increases the risk of STI transmission
- Intravenous drug use increases the risk of STI transmission
- Mother-to-child transmission during pregnancy, childbirth, or breastfeeding is possible
