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.
HSV asymptomatic shedding occurs at some time in most individuals infected with herpes. It can occur more than a week before or after a symptomatic recurrence in 50% of cases. Virus enters into susceptible cells by entry receptors such as nectin-1, HVEM and 3-O sulfated heparan sulfate. Infected people who show no visible symptoms may still shed and transmit viruses through their skin; asymptomatic shedding may represent the most common form of HSV-2 transmission. Asymptomatic shedding is more frequent within the first 12 months of acquiring HSV. Concurrent infection with HIV increases the frequency and duration of asymptomatic shedding. Some individuals may have much lower patterns of shedding, but evidence supporting this is not fully verified; no significant differences are seen in the frequency of asymptomatic shedding when comparing persons with one to 12 annual recurrences to those with no recurrences.
When a herpes outbreak occurs, you can expect cold sores to take about 10–14 days to heal on average. During this time period, the virus is considered to be active, and you should be very careful to avoid direct contact between a sore and someone else. If after trying the natural remedies for herpes described above you still experience frequent recurrences, talk to your doctor for how to get rid of herpes symptoms. Sometimes immunity is suppressed due to another infection or virus, or even as a side effect of taking some medications, so be sure to rule these causes out.
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.
However, there is much more to the herpes virus than just chicken pox or genital herpes. For instance, after an active infection, the virus is shed (eliminated) in the urine and feces for up to several months (sometimes years in the case of the cytomegalovirus) after the active infection has resolved. This means the infected person is still contagious, which is what makes this virus so contagious. It can easily be transferred when the patient is asymptomatic.
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.
