What is herpes?
Herpes is the name of a group of viruses that cause painful blisters and sores. One kind of herpes (herpes simplex virus or HSV) causes both cold sores around the mouth and genital herpes (herpes around the sexual organs). Herpes zoster is another kind of herpes, and it causes chickenpox and shingles.
How is genital herpes spread?
Genital herpes is spread easily. The virus from contact with an infected person can enter your body through a break in your skin or through the skin of your mouth, penis or vagina, urinary tract opening, cervix or anus. Herpes is most easily spread when blisters or sores can be seen on the infected person. But it can be spread at any time, even when the person who has herpes isn’t experiencing any symptoms.
Genital herpes is usually spread from one person to another by having sex, including oral sex. Herpes can also be spread from one place on your body to another, such as from your genitals to your fingers, then to your eyes or to other parts of your body. Herpes can also be spread from a mother to her baby when she gives birth.
What should I do if I think I have herpes?
See your doctor as soon as possible. Herpes is easier to diagnose when there are sores. You can start treatment sooner and perhaps have less pain with the infection.
What happens once someone is infected?
Once you have been infected with the virus, you'll go through different stages of infection. Each stage is explained in the following sections.
Primary stage
This stage usually starts 2 to 8 days after you're infected, but it can take much longer to begin. Usually, the infection causes groups of small, painful blisters. The fluid in the blisters may be clear or cloudy. The area under the blisters will be red. The blisters break open so easily that they quickly become open sores. You may not ever notice the blisters.
Besides having tender blisters or sores in your genital area, it may hurt to urinate. You may run a fever, feel achy and have other flu-like symptoms.
While most people have a painful primary stage of infection, some don't have any symptoms at all, and may not even know they're infected.
Latent stage
During this stage, there are no blisters, sores or other symptoms. At this time, the virus is traveling from your skin into the nerves near your spine.
Shedding stage
In the shedding stage, the virus starts multiplying in the nerves. It can then get into body fluids, such as saliva, semen or vaginal fluids. There are no symptoms during this stage, but the virus can be spread during this time.
Recurrences
Many people have blisters and sores that come back after the first herpes attack goes away. This is called a recurrence. Usually, the symptoms aren't as bad as they were during the first attack.
Stress, being sick or being tired may start a recurrence. Being in the sun or having your menstrual period may also cause a recurrence. You may know when a recurrence is about to happen because you may feel itching, tingling or pain in the places where you were first infected.
Is there a cure for herpes?
No. But medicines can help. The medicine acyclovir can speed up healing and can lessen the pain of herpes for many people.
Acyclovir pills can treat primary or recurrent herpes and can stop or lessen the number of recurrences. Acyclovir also comes in a cream to put on sores during the primary stage or during recurrences.
Famciclovir and valacyclovir are other medicines used to treat recurrent genital herpes and for prevention of recurrences.
