Z Herpes Simplex Virus Herpes is one of the most common sexually transmitted infections. It is caused by the herpes simplex virus HSV. Most Canadians will have at least one type of HSV in their lifetime. Many of those people have never had symptoms and are not aware that they have HSV. There are two types of herpes simplex virus: For many people, herpes is a minor skin condition that comes and goes without causing problems.
HSV-1 is commonly found around the mouth, and is often called "cold sores". It can be passed to the genitals through oral sex. HSV-2 is commonly found in the genital area, but it can be passed to the mouth through oral sex.
Both types are sometimes passed to other areas of the body through skin-to-skin contact. After the first outbreak, HSV stays in the body and becomes inactive. The virus may become active from time-to-time. When this happens, symptoms usually show up in the same general area as the first time. There is no way of knowing if, or how often, a person will have future outbreaks. For most people, outbreaks happen less often over time.
Causes HSV is spread by direct skin-to-skin contact. HSV can be passed even when sores are not visible, although it is less likely to happen during these times. Sometimes the virus can be found on the skin even when there are no symptoms. This is called "asymptomatic shedding". Once you have one type of HSV, it is unusual to get the same type on another area of your body. The exception is within the first few months after a person first gets HSV.
HSV can be passed to other parts of the body during this time. Try not to touch the sores and wash your hands often, to lower the chances of passing it to another part of your body. If you have one type of HSV, then it is not possible to get that same type again from a new partner.
Symptoms A person can have HSV and not know it. Symptoms may not appear for months or years. Many people who do get symptoms do not realize that they are caused by HSV.
The first time a person comes in the contact with the virus and gets symptoms is called a primary outbreak. Usually symptoms begin 2 to 21 days after contact. The first outbreak can last longer and be more severe than future outbreaks. Early symptoms include itching, burning, or tingling at the site where blisters or sores may appear, followed by painful red sores or tiny blisters and sometimes swollen glands, fever and body aches. Sometimes people have severe flu-like symptoms, such as fever, headache and muscle aches.
Over time, outbreaks usually happen less often and the symptoms are milder. Herpes sores may be triggered by different things. Some triggers that people describe include sun exposure, lack of sleep, alcohol use, stressful events and skin irritation. Symptoms may be reduced by getting enough sleep, eating well and minimizing stress.
Complications Complications are rare and most often occur with the first herpes outbreak. During this time, it is possible to spread HSV to other areas of your body, such as the hands and fingers, anus and eyes. To lower the chances of this, try not to touch the sores and wash your hands often.
A pregnant person can pass genital herpes to the baby during childbirth. This is most likely to happen if the person has their first outbreak near the time of delivery. Talk to your doctor if you have any questions about herpes and your pregnancy.
Severe complications, although extremely rare include: Ongoing, frequent and painful outbreaks Ocular eye herpes Brain infection and inflammation encephalitis or meningitis See your health care provider if you are concerned about symptoms or complications.
Tests and Diagnosis The best test for herpes involves taking a swab from the sore as soon as possible after it develops.
Results will usually come back within 7 to 10 days, but some clinics may take longer. Blood tests are not routinely done, but in some cases e. Most blood tests are accurate 12 to 16 weeks after possible exposure to HSV. A positive herpes test does not tell you how long you have had the virus or where it will show up on the body. Treatment Antiviral medication can lessen the severity of an outbreak, lower the chances of passing the virus to a partner and shorten the time it takes for a sore to heal.
Medication works best if it is started as soon as possible after an outbreak begins. It is not necessary to treat herpes, but you can talk to your doctor or health care provider if you want more information about this medication.
