Sex
Stage 1 of syphilis?
Painless sore on contact part, three weeks after infection. (Penis, mouth, vulva, inside anus, vagina). Will heal itself in three weeks.
Stage 2 of syphilis?
After six weeks to six months skin gets red rashes.
Ulceration results - large ulcers develop on body.
Swollen lymphs glands in pelvis
Flu-like symptoms: fever, weight loss
Hair loss
Stage 3 of syphilis?
Not treated, goes into latent stage for several years.
Numbness, paralysis, loss of coordination, brain damage can occur.
Can also get stroke, dementia and insanity can be result.
Blindness and deafness can also set in.
Heart diseases, cardiac muscle damage, blood vessel damage occurs.
Damage of eg liver, skeletal, joints.
Death
How do you treat syphilis?
Antibiotic
In early stage: single injection of long - acting penicillin.
Also effective in large doses treating later stage.
Will kill bacterium and prevent further damage, but cannot cure damage already done.
How do you prevent STI’s?
Monogamous: one sexual partner
Abstinence only way 100% clean
Barrier contraception: condoms femidoms reduce chance infection
Education about infections
Not drugs or alcohol increase risky behavior risk of sexual assault possible exposure to STI’S.
