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.
