Herpes Simplex Virus I & II

What exactly are Herpes Simplex Virus I & II?

Herpes Simplex Virus (HSV) is a virus that causes infections in humans. There are two types: HSV type 1 and HSV type 2. HSV type 1 most commonly causes cold sores or blisters around the mouth, while HSV type 2 more often causes genital herpes, including blisters or sores around the genitals. However, both types can occur in either location. Once infected, the virus remains in your body for life.

How does a Herpes Simplex Virus I & II infection usually progress?

After the initial HSV infection, you may develop symptoms, but you may also notice nothing at all. The virus then remains dormant in your body. It can become active again, for example during periods of stress, illness or reduced immunity. This can cause symptoms such as blisters or sores to return. The first outbreak is often the most severe. Subsequent outbreaks are usually milder and shorter.

What are the symptoms and typical complaints of Herpes Simplex Virus I & II?

HSV type 1 most commonly causes cold sores: a painful blister or sore on or around the lips. Blisters can also occur in or around the mouth. HSV type 2 often causes painful blisters or sores on or around the genitals, anus or buttocks. Other symptoms can include itching, a burning sensation, pain when urinating and swollen lymph nodes in the groin. Not everyone develops symptoms; some people do not notice anything at all.

Where can you contract Herpes Simplex Virus I & II and how common is it?

HSV can be contracted through direct contact with someone who carries the virus. This can occur through kissing (particularly HSV type 1) or sexual contact (particularly HSV type 2). The virus can also be transmitted through shared items such as towels, although this is uncommon. Herpes is very common: around 50% of adults have HSV type 1, while approximately 10–20% have HSV type 2.

Are there specific risk groups for Herpes Simplex Virus I & II?

Anyone can contract herpes, but people with multiple sexual partners may have a higher risk of acquiring HSV type 2. People with a weakened immune system, for example due to certain illnesses or medications, may also be more likely to develop symptoms or experience more severe outbreaks.

How can you prevent infection with Herpes Simplex Virus I & II?

It is not always possible to prevent HSV infection, but you can reduce the risk. Use condoms or dental dams during sexual contact, particularly if you or your partner has symptoms. Avoid kissing or intimate contact when someone has a cold sore. Avoid sharing towels, lip balm or cutlery during an outbreak.

Which hygiene or behavioural measures can reduce the risk of Herpes Simplex Virus I & II?

Wash your hands thoroughly after contact with blisters or sores and avoid touching them unnecessarily. Use your own towel, washcloth and lip balm. A healthy lifestyle can also help support your immune system.

How can you prevent further transmission if you already have Herpes Simplex Virus I & II?

During an outbreak, avoid kissing, oral sex and unprotected sexual contact until the blisters or sores have healed. Wash your hands after touching the affected area. Tell your partner(s) if you have an outbreak so that they can also take appropriate precautions.

Can Herpes Simplex Virus I & II be treated, and if so, how?

Herpes cannot currently be cured; the virus remains in your body. However, antiviral medicines can reduce symptoms and shorten the duration of an outbreak. These are usually available as tablets and, in some cases, creams. If you experience frequent or severe outbreaks, a doctor may prescribe longer-term antiviral treatment to help prevent new outbreaks.
