Lesson Content/Board Summary

Sexually Transmitted Infections (STIs) and HIV/AIDS

Meaning of Sexually Transmitted Infections (STIs)

Sexually Transmitted Infections (STIs) are infections that are passed from one person to another through sexual contact. They can be caused by bacteria, viruses, or parasites.

Meaning of HIV/AIDS

HIV stands for Human Immunodeficiency Virus. It is a virus that attacks the body’s immune system, making it difficult for the body to fight off other infections and diseases.

AIDS stands for Acquired Immunodeficiency Syndrome. It is the most advanced stage of HIV infection, where the immune system is severely damaged, leading to serious illnesses.

Types of STIs

The following are common types of STIs:

  • Gonorrhea
  • Syphilis
  • Chlamydia
  • Genital Herpes
  • Human Papillomavirus (HPV)
  • Hepatitis B
  • HIV (Human Immunodeficiency Virus)

Causes of STIs

STIs are primarily caused by the transmission of bacteria, viruses, or parasites from an infected person to another. The common ways STIs are spread include:

  • Unprotected Sexual Contact: This is the most common way STIs are transmitted, including vaginal, anal, or oral sex without a condom.
  • Sharing Contaminated Needles: Sharing needles for drug injection or other purposes can transmit blood-borne STIs like HIV and Hepatitis B.
  • Mother-to-Child Transmission: Some STIs can be passed from an infected mother to her baby during pregnancy, childbirth, or breastfeeding.
  • Blood Transfusion: In rare cases, STIs can be transmitted through infected blood transfusions, though blood screening significantly reduces this risk.
