How likely will I get hepatitis B in this exposure?

[Marts123456]

I had unprotected vaginal sex with a girl twice on December 17-18 (one each day). First day 3 minutes no condom, 2nd day, used condom for a few minutes then no condom for another 3 minutes. Girl had bacterial vaginosis have no idea on her STD profile. She is probably near the low class and had many sex partners. She said she doesn't have STD's but she is willingly having sex with a person she met on tinder without a condom even if I suggested it to her. And I know hepatitis B is especially quiet with symptoms.

In our country the number of cases of Hepatitis B are around the 20 million with a population of 100,000,000 so there is a 20% prevalence rate in our country. I never knew things were this serious until today. What are the chances of me acquiring Hepatitis B in this encounter? Also when can I test for it if ever? I plan to take a blood test at 6 weeks.

Bro don't bother about hep b and c just b concerned about HIV. Go get p53 antigen test done immediately for HIV and start taking post exposure prophylaxis treatment for 30days without wasting a single more min now. Although if u r sure lady isn't infected with HIV then cool down no need to worry about hep b and c coz they are self limiting if infected at Ur age

To do for a blood test after 6 weeks of exposure should be ok. If you make it 12 weeks even better as you would get the most accurate result. Please include HIV, Hep C, Syphilis besides Hep B test. Wish you all the best!

Isn't Hep C unlikely as sexual contact disease? I'm taking a blood test for HIV and Hep B on January 29. My exposure was around December 17-18. Exactly 6 weeks. You think I still should be tested for syphilis?

[ajnasution]

Hep C can be infected through vagina fluids. Therefore Hep C is one of the STDs. For peace of mind I would urge you to be tested for syphilis.

Thanks i'll get tested for hep C and hep B and HIV next week then.

I remember getting vaccinated for one of the hepatitis strains about 10 years ago. I am not sure if that was Hep A or Hep B. I would feel it is most likely Hep B given the prevalence

[ajnasution]

If you have been vaccinated of both Hep A & Hep B about 10 years ago, most likely you will have to need to be vaccinated again. You may also check your HBsAb quantity level when you do your HBsAg test. If your HBsAb is more than 10 mIU/mL , you are protected against the Hep B virus.

Thank you I might as well get vaccinated again given the millions of people with the disease in my country.

I think you need to be very careful of having unprotected sex. It is a wisdom you need to learn. The lady might be infected with HIV and you don't want to contact that. I think you need to go for comprehensive tests to screen Hepatitis and HIV for early detection. What country are you from?

I always use a condom this was the only time I did not. I was more concerned with pregnancy and I forgot about STD's completely. I'm from the Philippines
