Good news
Syphilis can be easily treated by medications prescribed by the doctors.
Bad news
IF NOT TREATED, Syphilis causes terrible symptoms and then kills.
How does it look if you got it
First, the patient gets a SINGLE PAINLESS ULCER where the entry point was. If it was kissing, the ulcer will be on the lips. If it was sexual contact – ulcer will be on genitals. If anal intercourse occurred, the ulcer will locate around the anus.
Much later, IF NOT TREATED, there is a rush on the neck and chest looking like many many pimples.
Later on, IF NOT TREATED, the patient will become mentally retarded and die.
What to do
See your GP very very promptly! All will be OK if you get to the doctor soon.
What NOT to do
Do not kiss anyone or share cups, cigarettes or bongs with others. Do not have sex with anyone.
Things to watch out for
Nothing much, really.
One can get some other infections via kissing. The chances are low though. The best thing is to speak to a doctor or a nurse.
