Symptoms of shingles include tingling, numbness, pain, burning, skin that is sensitive to the touch, itching, and fluid-filled blisters that open and crust over. It is caused by the same virus that causes chickenpox. One of these is shingles, which is a viral infection that typically causes a single strip of blisters wrapping around one side of the torso. Other medical conditions can cause skin rashes that look similar to the herpes rash. HSV-2 is usually diagnosed through a blood test, although a doctor can also swab the sores to test for the herpes virus. The first outbreak may also result in:Ī doctor can diagnose a herpes rash based on the appearance of the blisters and lesions on the skin, as well as with laboratory tests. In many people, the first sign of a herpes rash outbreak is an itching, burning, or tingling sensation in the area where the outbreak will occur. What Are Common Symptoms of a Herpes Rash? It will then move back into the nerves to remain dormant until the next outbreak.Ĭertain factors can increase your risk of having outbreaks. When it is active, the virus moves to the mucous membrane or skin of the infected area and copies itself, causing the outbreak to occur. After the initial exposure, the herpes virus invades the nerves in the body that supply the skin area, remaining in those nerves for the rest of the person’s life. The herpes virus causes the rash to break out on the skin. The risk of spreading the virus increases during an outbreak. Genital herpes is generally spread through vaginal and anal sex, although it can be transmitted through oral sex. Any type of contact to the affected area can cause the virus to spread to your sexual partner. During an outbreak, you should not engage in sexual contact with a person who is not infected with the virus, as doing so can spread it. The shallow sores crust over and heal in about a week or so, although in some people, the rashes take up to six weeks to clear up. The rash appears as small, painful blisters with clear or yellowish fluid inside. These rashes occur in the genital area, which can include the labia, vagina, cervix, anus, penis, scrotum, thighs, or buttocks. Herpes simplex virus type 2 (HSV-2) is the cause of most genital herpes. Oral herpes can be transmitted to other areas of the body as it is passed through skin-to-skin contact with the infected area. It takes about two weeks for most cold sores to develop, break, and then heal. When the blisters break, the fluid oozes out and leaves behind an open, painful sore that crusts over once it dries. Sometimes, these spots merge together and form a larger blister. When an oral herpes outbreak occurs, small, red blisters filled with a clear, yellowish fluid appear. The virus can lead to blisters or rashes that develop primarily on and around the lips (known as cold sores) but can also appear on the gums, mouth, or throat. Most oral herpes rashes are caused by herpes simplex virus type 1 (HSV-1). The first outbreak is often the worst and most painful, with future outbreaks lessening in severity.
The location of the outbreak often depends on where the affected person was first exposed to the virus.Īt this point, no cure is available for herpes, which means people can experience outbreaks of the herpes rash at any time. This virus causes small sores to develop on the skin, often around the nose and mouth or genitals, although they can develop anywhere on the body.
What Is a Herpes Rash?Ī herpes rash, also known as an outbreak, is the body’s response to the presence of the herpes virus. Many people with the herpes virus never develop a rash or any other symptoms of an infection. The rashes might develop repeatedly, but you can take medications to help prevent or shorten outbreaks. The location of the rash depends on which type of herpes virus you have. A herpes rash looks like a cluster of small, fluid-filled blisters near the mouth or genitals.
