This is a question from my friend, my friend is from China, he can not visit medhelp, so please ask me to ask him about the risks
He had a protected sex with a sex worker, unprotected oral sex。
Skin damage to the glans after 17 days and erythema after 30 days
But he detected syphilis at 4, 6, 8, 10, 13, 19, 24 weeks are all negative。
He was very worried about this. Chinese doctors said it was psoriasis, simple balanitis, and eczema. There is no definite answer.
He is still very worried that he has syphilis.
He wants to know what is his chance of getting syphilis。
Thanks ALL
