Dear Doctor,
I am 35, an asian male from China. I had sexintercourse with a commericial sexworker in Tianjin, a city in north China on July 10. But she is from south China. I used a condom which she gave me at the beginning. But when finished I found that condom was fully broken. Therefore I had ejaculated directly in her viginal. I cannot be sure when that condom broke. I had actually unprotected viginal sex with her (for a few minutes, I guess) and ejaculation in her. I was worried about HIV infection since then. On August 08, I got Oral ulcer. I was very worried because I think it could be a symptom for initial HIV infection. So I didnot wait longer and went to a hospital the next day (on August 09, about 30 days post) and took a HIV-antibody test, the result was negative, which gave me some relief. But I found yesterday (August, 10) (no intentionally) I had probably Lymph node ache?(below my left jaw), it hurts a little by pressure and when i open my mouth widely. There is also a little swollen from outside. Because I am not a doctor I cannot tell if I actually have Swollen lymph nodes. But I never had this symptom before. . Today, on August 11, the symptoms remains (Oral ulcer and left jaw ache) and I get also some slight symptoms of cold. I am afraid these could be symptoms of a initial HIV infection. Could you please be so kind and tell me:
1. How convinced is a 4 weeks HIV-antibody test after exposure? I have also read some chinese AIDS/HIV forums, there are different opions about windows time (4 weeks, 6 weeks and 3 months...) Is there a difference in window period according to races?
2. I plan to take a new HIV virus test. When should I do this? Is it in six weeks after exposure ok or should i wait longer?
3. Could these symptoms I had newly be initial HIV-infection symptoms? That means, my body produce HIV-antibody slowly (after 4 weeks post exposure) and I will get antibody in my body after these symptoms? How probably is this?
Thank you.
