Have PCR test for HSV and start Rx even if the diagnosis isn't certain; if not herpes, it won't do any harm. Good luck! ...Read more

Most children get it between 3mos and 3yrs of age and by age 60 somewhere between 65 and 85% of people are infected. You do not need cold sores to be shedding the virus and infecting others. ...Read more

That can happen in the first few weeks of a new herpes infection, but after that the immune system prevents it. The main cause of vaginal itching and irritation is yeast infection (thrush). See a doctor for diagnosis and treatment. ...Read more
