Syria— Genital herpes infection from HSV-2 is predicted to be low in Syria although HSV-1 levels are high. HSV-1 infections is common (95%) among healthy Syrians over the age of 30, while HSV-2 prevalence is low in healthy individuals (0.15%), and persons infected with other sexually transmitted diseases (9.5%).
For HSV-2, subclinical shedding may account for most of the transmission. [11] Studies on discordant partners (one infected with HSV-2, one not) show that the transmission rate is approximately 5–8.9 per 10,000 sexual contacts, with condom usage greatly reducing the risk of acquisition. [13]
For Herpes simplex virus 2, subclinical shedding may account for most of the transmission. [7] Studies on discordant partners (one infected, one not) show that the transmission rate is approximately 5 per 10,000 sexual contacts. [9] Atypical symptoms are often attributed to other causes, such as a yeast infection. [5] [10]
Worldwide rates of either HSV-1 and/or HSV-2 are between 60 and 95% in adults. [4] HSV-1 is more common than HSV-2, with rates of both increasing as people age. [4] HSV-1 rates are between 70% and 80% in populations of low socioeconomic status and 40% to 60% in populations of improved socioeconomic status. [4]
In 2015, about 846 million people (12% of the world population) had genital herpes. [4] In the United States, more than one in six people between the ages of 14 and 49 have the disease. [8] Women are more commonly infected than men. [1] Rates of disease caused by HSV-2 have decreased in the United States between 1990 and 2010. [1]
The risk of transmission to the newborn is 30–57% in cases where the mother acquired a primary infection in the third trimester of pregnancy. Risk of transmission by a mother with existing antibodies for both HSV-1 and HSV-2 has a much lower (1–3%) transmission rate.
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people.. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...
