Gential Herpes
Genital herpes is a common sexually transmitted infection caused by the herpes simplex virus (HSV). There are two types, HSV-1 and HSV-2, both of which can cause infection in the genital and anal area (genital herpes). Herpes simplex can also occur around the mouth and nose (cold sores) and fingers and hand (herpetic whitlows).
In women, genital herpes can occur on the skin in and around the vagina, the vulva (lips around the opening of the vagina), the urethra (tube through which urine empties out of the bladder) and the anus (back passage). In men, it can occur in the skin of the penis, the scrotum, the urethra and the anal area.
Genital herpes is usually passed from one person to another during sexual contact. Both women and men can get it. The virus enters the body through small cracks in the skin or through the thin skin of the mouth or genital area. Once you have the virus it stays in your body for life although it remains inactive for most of the time.
You may only get one episode or you may have repeated flare-ups. It can be passed on:
through skin-to-skin contact with the affected area when the virus is active by having unprotected vaginal, anal or oral sex or by sharing sex toys.
Some people have no signs or symptoms at all. Some people just get a few blisters in the genital area, which are not particularly painful. Flare-ups are usually mild. An early-warning tingling sensation often happens before the flare-up occurs.
However, for some people, the symptoms can be very painful. This is particularly so if it is your first episode when you may also feel unwell and notice very painful sores or watery blisters. Symptoms can occur within a short time of coming into contact with the virus or it may take many weeks, months or years before any signs or symptoms appear.
Contact your doctor or a clinic that specialises in sexually transmitted infections (called genitourinary medicine clinics or sexual health clinics). You should have a check-up that will include testing, treatment and advice. It is possible to have more than one sexually transmitted infection at the same time. You may be offered testing to check for other infections too.
If your first episode happens in the first 3 months of pregnancy, your baby is not more likely to have developmental problems and your risk of miscarriage is not increased. Later in pregnancy, a first episode should not affect your baby unless you are in labour (see below).
If you go into labour less than 6 weeks after a first episode of genital herpes, your immune system won’t have had time to produce antibodies to protect your baby. There is thus a high chance of passing the virus to your baby if you have a vaginal birth. If your first episode is earlier in pregnancy, your immune system will provide protection to your baby.
When a baby catches the herpes virus at birth, it is known as neonatal herpes. It can be serious but is very rare in the UK (1–2 out of every 100 000 newborn babies). Your baby will be looked after in a neonatal unit by a specialist team of doctors.
- If your first episode is before 28 weeks of pregnancy, you may be offered antiviral treatment at that time and again from 36 weeks of pregnancy until your baby is born
- If your first episode is at or after 28 weeks of pregnancy, you will be advised to continue your treatment until your baby is born.
- If your first episode is late in pregnancy (within 6 weeks of your due date), you should be offered a planned caesarean section to reduce the chance of your baby getting neonatal herpes.
- If your first episode is earlier in pregnancy, the risk to your baby is low and you can have a vaginal birth. You can discuss this further with your consultant obstetrician.
- If you have caught genital herpes before you become pregnant, your immune system will provide protection to your baby in pregnancy. Flare-ups of genital herpes during pregnancy do not affect your baby. Even if you have a flare-up when you go into labour and give birth, the risk to your baby is extremely low. Most women who have recurrent genital herpes can have a vaginal birth. Your doctor will discuss this with you.
- If you have frequent flare-ups during pregnancy, you may be offered continuous antiviral treatment from 36 weeks of pregnancy to birth.
