Epidemiology Of Herpes
Although HSV-1 and HSV-2 are usually transmitted by different routes and involve
different areas of the body, there is an overlap in the epidemiology and clinical manifestations. These viruses are distributed worldwide, and infection occurs in both developed and developing countries. Animal vectors of human HSV infections have not been described, and humans remain the sole reservoir for transmission to other humans.
Virus is transmitted from infected to susceptible individuals during close personal contact. There is no seasonal variation in the incidence of infection. Because HSV infection is rarely fatal, and HSV establishes latency, more than one-third of the worlds population has recurrent HSV infections and, therefore, the capability of transmitting HSV during episodes of productive infection.
Geographic location, socioeconomic status, and age influence the frequency of HSV-1 infection. In developing countries, seroconversion occurs early in life. In lower socioeconomic populations, approximately one-third of children have serological evidence of HSV infection by 5 years of age; this frequency increases to 70%-80% by early adolescence.
Predictably, middle-class individuals acquire antibodies later in life, such that seroconversion over the first 5 years occurs in 20% of children, followed by no significant increase until the second and third decades of life, at which time the prevalence of antibodies increases to 40%-60%. The annualized rate of infection among university students averages 5%-10%.
The seroprevalence of HSV-1 and HSV-2 infections has been redefined by using type-specific serological assays and sera obtained from the randomized National Health and Nutrition Examination Survey. By the age of 5 years, over 35% of African American children are infected by HSV-1, as compared with 18% of Caucasian children.
Through adolescence, the prevalence of antibodies to HSV-1 is approximately twofold higher among African Americans than among Caucasians, and the prevalence of antibodies is slightly higher among females than among males. By the age of 40 years, the prevalence of antibodies to HSV-1 is similar among both African Americans and Caucasians.
Similarly, a high prevalence of antibodies to HSV-1 exists worldwide, but there is a high rate of country-to-country variation. Infections with HSV-2 are usually acquired through sexual contact and, therefore, antibodies to this virus are rarely found before the age of onset of sexual activity. Although most genital HSV infections are caused by HSV-2, an ever-increasing proportion is attributable to HSV-1.
The distinction in virus type is not insignificant, since genital HSV-1 infections are usually both less severe clinically and less prone to recur. The number of new cases of genital HSV infections has been conservatively estimated to be about 500,000 annually, and approximately 40 million to 60 million Americans are infected latently with HSV-2.
Outbreaks are commonly accompanied by pain, itching, or burning. Some experience enlarged lymph nodes, muscle pain, and fatigue with genital herpes. Unfortunately, there is no known cure for herpes virus strains themselves. Advertised cures for herpes cure only the symptoms. Use of a condom is recognized to be the most reliable method to prevent transmission of the virus. The best genital herpes cure is prevention.
However, there are herpes cures against the frequency and severity of outbreaks. Other treatments stop viral reproduction, and reduce viral load, all of which greatly mitigate outbreaks and allow sufferers to control the condition and vaccines cause resistance to infection. As new chemical drug options are not viable, alternative antiviral herpes cures are being investigated with great interest.
Recent scientific studies of medicinal antiviral plant extracts show very encouraging results for a herpes cure, and have sparked a new methodology for treating herpes. HSVCurative is a potent all natural antiviral cure for herpes, highly effective against HSV1 and HSV2, it has a wide spectrum of antiviral activity against these viruses, even for genital herpes.
The cure in this treatment has the ability to inactivate and destroy HSV, which has been established in published clinical trials. The antiviral extracts represent new effective treatment options for therapeutic use as virucidal agents for recurring herpes infections. To learn more, please go to http://www.bcured.net.
