Three sexually transmitted infections (STIs) that can be life-threatening or lead to life-threatening illnesses are HIV, syphilis, and hepatitis B.

HIV (Human Immunodeficiency Virus)

  • HIV attacks the immune system, potentially leading to AIDS, which is life-threatening if untreated due to the risk of opportunistic infections and cancers.
  • Without proper treatment, HIV progressively weakens the body’s ability to fight infections.

Syphilis

  • Untreated syphilis can cause severe damage to the heart, brain, and other organs over time, which may be fatal.
  • It can also be transmitted from mother to child, leading to stillbirth or life-threatening complications in newborns.

Hepatitis B

  • Hepatitis B virus (HBV) can cause liver cirrhosis and liver cancer; both complications can be fatal if not managed.
  • Chronic hepatitis B infection significantly increases the risk of liver failure and death.

These infections illustrate why prevention, early diagnosis, and appropriate treatment of STIs are critical for overall health.
