Herpes symptoms commonly show in or around the mouth. Sores may also occur at the back of the throat, causing the lymph nodes in the neck to swell. Mouth herpes is very common in children, as their parents or relatives can pass it on to them easily by a greeting or goodnight kiss. To get a better understanding of oral herpes, let us take a look at its causes.
A scary finding is that more cases of genital herpes than ever before are now being caused by HSV-1 (the type most people assume only causes mouth sores), and about 85 percent of people with genital herpes don’t even know it. (7) Studies show that about 50 percent of the new genital herpes infections in young adults are due to HSV-1 and about 40 percent in older adults. The fact that most people don’t ever find out they’re infected is one of the reasons that transmission rates are steadily climbing.
Oral herpes (HSV-1) infection (or exposure without noticeable infection) is common. About 65% of the U.S. population has detectable antibodies to HSV-1 by age 40. This article will focus on HSV-1, or oral herpes, not on HSV-2, also commonly known as genital herpes. Genital herpes is considered to be a sexually transmitted disease (STD). In addition, HSV-2 virus should not be confused with human papillomavirus (HPV), the cause of genital warts, and some cervical and other cancer types.
The broader issue is whether, if you do get infected, herpes will ultimately harm your health. Although I don’t want to trivialize this infection, in your general scheme of health, it probably will not. The major concern is that if you are pregnant and develop a new outbreak of herpes, the virus can be transmitted to the fetus, especially during vaginal delivery. What’s more, people with genital herpes have a much greater risk of acquiring HIV if they are exposed. (It’s theorized that the lesion causes microscopic breaks in the skin, allowing HIV to enter the body.)
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.
Herpes infection can be passed from you to your unborn child before birth but is more commonly passed to your infant during delivery. This can lead to a potentially deadly infection in your baby (called neonatal herpes). It is important that you avoid getting herpes during pregnancy. If you are pregnant and have genital herpes, you may be offered anti-herpes medicine towards the end of your pregnancy. This medicine may reduce your risk of having signs or symptoms of genital herpes at the time of delivery. At the time of delivery, your doctor should carefully examine you for herpes sores. If you have herpes symptoms at delivery, a ‘C-section’ is usually performed.
