Syphilis
Transcript
Syphilis
Stage 2
What is it?
- The pathogen spreads through the blood to the skin, liver, joints, lymph nodes, muscles, and brain.
- A rash frequently appears about 6 weeks to 3 months after the chancre has healed.
- At this time, the disease is highly infectious, because bacteria are present in the secretions from the lesions.
- A chronic bacterial disease that is contracted by infection during sexual intercourse, but also congenitally by infection of a developing fetus
- Syphilis is spread through vaginal, oral, and anal sex during the infection's primary, secondary, and early latent stages.
Stage 1
Stage 3
Treatment
- Appears 2 to 10 weeks following exposure.
- A red, oval sore, called a chancre develops at the site where the bacteria entered the body.
- Most chancres appear on the penis, anus, and rectum in men, and on the vulva, cervix, and between the vagina and anus (perineum) in women.
- Penicillin is the standard treatment for primary, secondary, and early latent syphilis.
- For those allergic to penicillin, antibiotics tetracycline, doxycycline, minocycline, erythromycin, and ceftriaxone may be used, though less effective
- Begins 3 or more years after infection
- The person may no longer be contagious, but the bacteria may multiply and spread throughout the body, damaging the heart, eyes, brain, nervous system, bones, and joints
- Tumors may develop
- Degenerative central nervous system disease can produce dementia and damage is irreversible.
Diagnosis
- Diagnosed when the chancre on the genitals is observed and by reviewing the patient's sexual history
- Blood, serum, and plasma tests
