The epidemiology of herpes simplex is of substantial epidemiologic and public health interest. In many infections, the first symptom a person will have of their own infection is the horizontal transmission to a sexual partner or the vertical transmission of neonatal herpes to a newborn at term. Since most asymptomatic individuals simplsx 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. This information provides population prevalence of HSV viral infections in individuals with or without active disease. Note that there are population subgroups that are more vulnerable for HSV infections, such as cancer chemotherapy patients. Large differences in HSV-1 seroprevalence are seen in different European countries.

In most African countries, HSV-2 prevalence increases with age. However, age-associated decreases in HSV-2 seroprevalence has been observed for women in Uganda and Zambiaand in men in EthiopiaBeninand Uganda.
Women in Brazil are prebalence likely to acquire an HSV-2 infection if their male partners had history of anal prevalence and had many sexual partners in his lifetime. In India Indian men are more likely to be infected with HSV-2 than women, and increasing seroprevalence of this virus is associated with prevalene increasing age.
Israel— HSV-1 seroprevalence is These values are similar to levels in HSV infection in Europe. Antibodies for HSV-1 or HSV-2 are also more likely to be found individuals born outside of Israel, and individuals residing in Jerusalem and Southern Israel; people of Jewish origin simplex in Israel are less likely to possess antibodies against quote. In Australia, a herpes using data from revealed the seroprevalence of HSV-1 was at As in the U.

Curr Infect Dis Rep.Prevalence of HSV-1 during – was highest among Mexican-American persons and lowest among non-Hispanic white persons. Figure 1. Age-adjusted prevalence of herpes simplex virus type 1 among persons aged 14–49, by age group, sex, and race and Hispanic origin: United States, – Percent Total population unadjusted. Herpes simplex virus type 1 (HSV-1) infections are frequently asymptomatic but can produce a variety of signs and symptoms. These include oral or perioral lesions, ocular infections, nongenital skin lesions, genital skin or mucous membrane lesions, and serious systemic illnesses such as encephalitis and neonatal disease. This common virus causes cold sores, but it doesn't always cause symptoms.

These sores are called cold sores, fever blisters, or oral herpes.
