What is it?

Herpes is a very common and highly infectious virus which has two types:

  • Herpes Simplex Virus Type 1 (HSV I) - The most likely cause of cold sores, typically around the mouth. This virus can also be caught genitally through oral sex.
  • Herpes Simplex Virus Type 2  (HSV II) - The virus that typically causes sores, usually around the genitals. It may also be caught around the mouth through oral sex.

Your Better2Know test will tell you which (if any) type of the virus you have.

HSV I infection can occur in many sexual and non-sexual ways.  It is also responsible for about half of "genital herpes" cases. HSV II, or Genital Herpes, is typically caught on the genitals and is transmitted through sexual contact. Up to half of those who have HSV II are unlikely to know they are infected as their symptoms will be minimal or non-existent. They are capable of infecting partners through sex when the virus is present on the genitals causing pimples, little cuts, itchy or sore skin. Occasionally, the virus may be present with no visible signs and can still be passed on.  This is called 'asymptomatic viral shedding'.

1 in 4 people with Herpes have no symptoms, and 2 in 4 only have mild symptoms. Click here to see the full article.

How can I get it?

Herpes is spread through unprotected oral, vaginal or anal contact (it does not have to be sex) with an infected person. The risk of catching or transmitting the virus is highest when you or your partner has blisters or sores. It is still possible to get Herpes when your partner does not have any visible sores or blisters, but this is much less likely. Recurrent symptoms are almost always on visible skin.  Sores inside the vagina or anus are usually only present as part of a primary infection and are unlikely to accompany a recurrence.

HSV I is often spread by kissing which is why it is so common.

How do I know if I have it?

HSV may cause blisters on the genital areas of both men and women. These blisters typically develop within 2 days to 3 weeks after first getting infected. The blisters start off as small bumps, then grow into full blisters and burst, releasing fluid. Blisters can be small or large and can be just one blister, or many located close together. Other symptoms can include painful itching, burning, headache, swollen glands in the groin, and generalised muscle aches. The first episode or outbreak is usually the most severe with later outbreaks becoming milder. Most people catch the virus without developing these symptoms.

Herpes testing

Better2Know has three ways of testing for the virus:

  • Blood Test - our standard test whether or not you have symptoms
  • Urine Test - if you currently have symptoms
  • Swab Test - if you have a blister or other lesion for swabbing to see if it is caused by HSV.

At Better2Know you can choose your test method: urine or a swab if you have symptoms, and blood if you do not. Results are available 2- 5 working days from the sample being received in the lab depending on which sample is taken.  The test will say whether you have HSV I, HSV II, both types, or neither.


Like several other infections, once it is caught HSV I and HSV II stay in the body forever. A minority of those infected get recurrent outbreaks. Fortunately, there are ways to decrease the frequency and severity of the outbreaks.  Anti-viral medications are available (both creams and pills) which can help control the infection. In addition there are lifestyle changes which can also help to control the time between outbreaks and their severity. Better2Know can provide you with a prescription for medication and advice on lifestyle changes to help you control the infection if you test positive.

Most carriers of HSV need no treatment because symptoms are slight or non-existent. For those who experience recurrences there are several drugs which can help prevent or treat them. Healthy lifestyle changes can also make a difference.

Adverse consequences

Most people with Herpes are able to control their symptoms with medication.  It is advised to abstain from sex or to use a condom if you have symptoms.

Pregnant women who have carried the virus for some time are unlikely to pass the infection to their baby. However primary (first time) lesions that are exposed near the vaginal opening during delivery could cause the virus to be passed on to the baby potentially causing serious neo-natal infection.  In these cases a caesarean section is often carried out.  Unlike first time lesions, recurrences at term are very unlikely to cause this problem so a natural birth is recommended for most women. 

There is an increased chance of recurrent symptoms during pregnancy. These are not likely to harm your baby but this does mean that some women who have previously been asymptomatic may notice symptoms for the first time whist pregnant.  If you are in any way worried about Herpes and pregnancy please consult your midwife.
