85 of people with genital herpes don’t know they have it. When a person is not experiencing an outbreak, there is a 4-10 chance of transmitting it. Is herpes common? Herpes is more common than many might think, and a lot of people are unaware they are infected and may not even have symptoms to tip them off. Most say 25 of American women have the virus, and 20 of American males. Although many people infected with HSV develop labial or genital lesions, the majority are either undiagnosed or display no physical symptoms individuals with no symptoms are described as asymptomatic or as having subclinical herpes. Since most asymptomatic individuals are unaware of their infection, they are considered at high risk for spreading HSV. Many studies have been performed around the world to estimate the numbers of individuals infected with HSV-1 and HSV-2 by determining if they have developed antibodies against either viral species. The typical age at which HSV-1 infection is acquired ranges from 5 to 9 years in Central and Eastern European countries like Bulgaria and the Czech Republic, to over 25 years of age in Northern European countries such as Finland, The Netherlands, Germany, and England and Wales. Herpes simplex virus 2 (HSV-2) is the main cause of genital herpes.
Initial oral infection with HSV-1 may cause gingivostomatitis (mainly in children) and herpetic pharyngitis (mainly in adolescents and adults). Many people with genital herpes don’t know they have it, and are unaware they may be spreading virus to others. Similarly, for HSV-2, reactivation in the genital area is 8 to 10 times more frequent than oral reactivation. Most new cases of genital herpes infection do not cause symptoms, and many people infected with HSV-2 are unaware that they have genital herpes. Clusters of dimpled blisters emerge over 7 to 10 days and spread widely. Eighty per cent of the adult population is thought to carry HSV-1 and to have acquired it in a non-sexual manner. Some people infected with the genital herpes virus are unaware that they carry the virus — and may be unwittingly spreading the disease to their partners during sex, researchers report.
Herpes simplex virus 1 (HSV-1) is the main cause of oral herpes infections that occur on the mouth and lips. Most new cases of genital herpes infection do not cause symptoms, and many people infected with HSV-2 are unaware that they have genital herpes. Clusters of dimpled blisters emerge over 7 – 10 days and spread widely. They can become secondarily infected with staphylococcal or streptococcal bacteria. There are two types of the virus, types 1 and 2 (HSV-1 and HSV-2). Up to 80 of people get HSV from partners who have no signs and symptoms of HSV and are unaware they have the herpes infection. The blisters burst, leaving painful ulcers which dry, scab over and heal in approximately 10 days. A herpes infection is caused by the herpes simplex virus (HSV), which comes in two forms: HSV-1, which usually results in oral herpes infections affecting the mouth and lips; and HSV-2, which usually causes genital herpes affecting the genitals and anus. Most people get HSV-2 during sexual intercourse (vaginal or anal). In fact, an estimated 90 percent of people with HSV-2 don’t know they’re infected.
Herpes Virus HSV-1 And HSV-2 Transmission And Transmissibility
Table 7: Virologic Tests for Genital Herpes9,25,26. 10 to 25 percent of persons with HSV-2 infection have recognized genital herpes. Genital herpes; Fever blisters; Cold sores; HSV-1; HSV-2Highlights. Herpes Simplex Virus Type Two (HSV-2) usually affects the genital area. These flu-like symptoms are common to many other infections. Most people who have herpes virus on their genitals are unaware that they have the virus. I was diagnosed with genital herpes about 25 years ago. Dr. Shrier, a researcher on sexually transmitted infections, goes through this kind of conversation all the time. Anna Wald of the University of Washington, found that people who’d had symptoms of herpes shed virus on about 20 percent of days, while people who test positive for herpes antibodies but have never had symptoms shed virus on only about 10 percent of days. In the United States, more people have genital herpes than all other sexually transmitted infections combined – 50 million people in total. It is estimated that as many as one in five Americans have genital herpes, a lifelong (but manageable) infection, yet up to 90 percent of those with herpes are unaware they have it.12.
It also looks at the estimated prevalence of genital herpes and additionally considers the rates of STI notification in the Aboriginal and Torres Strait Islander population. Chlamydia is largely asymptomatic; most people are unaware that they have the infection and that they need treatment. For both men and women, the rate of diagnosis has increased over the past 10 years, particularly amongst people aged 45 years and over. Infection with HSV-2 is common; approximately 1 in 8 Australians aged 25 years and over have the virus (1 in 6 women and 1 in 12 men) (Endnote 7) and it is considered one of the most common STIs. An estimated 25 of American adults have genital herpes. Of all the people with the genital herpes simplex virus infection, only 1 in 5 are diagnosed and up to 80 of cases of genital herpes are not recognized as such by clinicians. Often the symptoms are so subtle that they are dismissed or the symptoms which do occur are usually misdiagnosed as being something other than the virus. Up to 1 million new genital herpes HSV-2 infections may be transmitted each year in the United States. People can also transmit herpes some of the time when they have no symptoms. The symptoms of a first outbreak of genital herpes usually appear 2 to 10 days after exposure to herpes and last an average of 2 to 3 weeks. Many people who are newly infected with herpes overlook their symptoms either because the symptoms are mild or because they are unaware of the possibility of herpes infection. Most persons with recurrent herpes due to HSV-2 have outbreaks 3 5 times a year. While neonatal herpes is rare, women who know they have genital herpes are often concerned about the possibility of transmitting the virus to their babies at birth. In addition, newly infected people – whether pregnant or not – have a higher rate of asymptomatic shedding for roughly a year following a primary episode. The risk is also high if she has prior infection with HSV-1 but not HSV-2.
