“Odds of contracting herpes?”

Chances are she may contract it as well. She could have blood test to confirm same or otherwise.

You ask an age-old question: can an infectious virus that can spread via contagious serous fluid from a lesion that is acting up be a cause of spread to another person? Absolutely. However, even with herpes simplex virus or HSV, the prodrome or pre-lesion irritation or discomfort is a signal that you have active and contagious virus that you can spread via direct contact skin to skin, skin to vaginal mucosal tissue or even oral mucosal and skin tissue. The contagious nature of HSV is the same whether it is the cold sore HSV-1 or the genital HSV-2; but know that HSV 1 can occur in an HSV-2 area and vice versa. The best way to check for HSV in an asymptomatic patient is by HSV antibodies via blood test to HSV-1 and HSV-2; doing a culture has a very low yield and does not give reliable results. Hope this helps.

Well let's not use words like 'clean' to describe any one here. But it would be difficult to put a number on that. lf the man was known to be positive for Herpes and was actively shedding virus (which he would not technically have known unless he was having an outbreak at the time of intercourse) he would be more likely to transmit the virus. Both women could be tested for antibodies to determine whether they were infected and if the exposure was recent or not. They should speak to their health care provider to determine the tests needed. I always recommend my patients that are positive for genital herpes use suppression medication, use condoms and inform their potential/prospective partners of their status before intercourse.

Depends what and if he had active herpes, when they had sex, and if the woman was immunocompromised. Less risk if condoms were used.

In general the odds are high, she should get tested.
Stay Healthy!
