Not every person with a herpes infection actually experiences breakouts of cold sores throughout his or her lifetime or even after initially becoming infected. How often someone has a herpes cold sore outbreak, how severe the outbreaks are, how contagious someone is after infection and how long the sores take to heal all depend on someone’s individual immune response.
Oral herpes is a viral infection mainly of the mouth area and lips caused by a specific type of the herpes simplex virus. Oral herpes is also termed HSV-1, type 1 herpes simplex virus, or herpes labialis. The virus causes painful sores on the upper and lower lips, gums, tongue, roof of the mouth, inside the cheeks or nose, and sometimes on the face, chin, and neck. Infrequently, it may cause genital lesions. It also can cause symptoms such as swollen lymph nodes, fever, and muscle aches. People commonly refer to the infection as "cold sores."
Jamie*, 29, is HSV-positive and contracted herpes from her husband. But, she explains, “He only had one outbreak when he was young and that was it. So he didn't realize what it was.” Jamie was infected three years into their relationship simply because he had outbreaks that infrequently. She says, “I was worried he had cheated on me, but then found similar stories online, and our outbreak patterns underscore that what happened is very possible.”
The HSV viruses multiply in the human cell by overtaking and utilizing most of the human cells functions. One of the HSV steps in multiplication is to take control of the human cell's nucleus and alter its structure. The altered nucleus (enlarged and lobulated or multinucleated) is what actually is used to help diagnose herpes simplex infections by microscopic examination. The reason sores appear is because as they mature the many HSV particles rupture the human cell's membrane as they break out of the cell.
Consequently, you may already have the virus. A doctor can determine this with a blood test for Herpes 2 (Ig), a type-specific immunoglobulin. If you are already infected, you won’t be at risk for a new infection — you and your boyfriend already share the virus. But knowing your herpes status will tell you whether you are capable of infecting a future partner.
When herpes flares up again, it is called a "recurrence" or "outbreak." Herpes does not always recur, and if it does recur, the timing and severity are different from person to person. Some people rarely have recurrences. Others have them often. Herpes is most likely to recur in the first year after infection. Recurrences may be more frequent for people with weakened immune systems.
The herpes virus can be shed from an infected person even when there are no lesions visible. So caution is important. Some may wish to take the daily prophylactic oral drug Valtrex (an antiviral oral medication) to help cut down on shedding. Herpes can also be transmitted on any skin: fingers, lips, etc. Depending on sexual practices, herpes simplex can be transferred to genitals and or buttocks from the lips of someone who has fever blisters. Honesty between partners is very important so these issues can be discussed openly.
Prescription antiviral medications are also commonly used to reduce the duration, severity, and incidence of outbreak. These medications include (but are not limited to) valacyclovir, acyclovir, and famciclovir. Remember that these medications will not cure HSV-1 or HSV-2. Instead, they will help reduce the amount of time the outbreak is present, and help control the severity of symptoms.

Laboratory testing is often used to confirm a diagnosis of genital herpes. Laboratory tests include culture of the virus, direct fluorescent antibody (DFA) studies to detect virus, skin biopsy, and polymerase chain reaction to test for presence of viral DNA. Although these procedures produce highly sensitive and specific diagnoses, their high costs and time constraints discourage their regular use in clinical practice.
A herpes infection is caused by the herpes simplex virus (HSV). It has 2 main types, including HSV-1 and HSV-2. While HSV-1 can cause oral herpes, HSV-2 can be responsible for genital herpes. Oral herpes is also known as cold sores or fever blisters. It mainly occurs on the lips, around the mouth. Genital herpes is usually referred to as herpes. It mostly affects the genitals and anal area. Genital herpes is considered to be a sexually transmitted disease. It’s extremely contagious and can be spread through sexual intercourse.
