Syphilis
Why in News?
Syphilis is in the news due to a landmark public health achievement in Europe and growing global concern over a "silent epidemic" characterized by a surge in cases and newborn deaths.
Key Features
- Causative Agent: A spiral-shaped bacterium called Treponema pallidum.
- The "Great Imitator": Often called this because its symptoms (like rashes and sores) mimic many other diseases, making it easy to misdiagnose.
Transmission
- Sexual Contact: Through direct contact with a syphilis sore (chancre) during vaginal, anal, or oral sex.
- Vertical Transmission: From an infected mother to her unborn baby (congenital syphilis).
- Blood: Rare transmission via blood transfusion.
Stages of Infection
- Primary: Characterized by a single, usually painless sore (chancre) at the site of infection. It heals on its own in 3–6 weeks, but the infection remains.
- Secondary: Marked by non-itchy rashes (often on palms and soles), fever, swollen lymph nodes, and fatigue.
- Latent: A "hidden" stage with no symptoms that can last for years or decades while the bacteria remain in the body.
- Tertiary: Occurs years after infection in untreated cases; can lead to severe damage to the brain, heart, eyes, and nerves, and can be fatal.
Prevention and Treatment
- Treatment: Effectively cured with Penicillin (specifically Benzathine Penicillin G). It is the only treatment recommended for pregnant women to prevent transmission to the baby.
- Prevention:
- Consistent and correct use of latex condoms.
- Regular screening for sexually active individuals and all pregnant women.
- Doxy-PEP: Using the antibiotic doxycycline within 72 hours of unprotected sex is an emerging prevention strategy for high-risk groups.
- Outcome: While antibiotics kill the bacteria and stop future damage, they cannot reverse organ damage that has already occurred.
