A study from the World Health Organization found two-thirds of the global population under the age of 50 has the herpes virus.
According to Reuters, the WHO determined over 3.7 billion people of that age range have herpes simplex virus type 1, typically only resulting in cold sores around the mouth. Most HSV-1 carriers caught the virus during childhood and are safe from the genital infections caused by herpes simplex virus type 2. The most extreme cases of HSV-1 can lead to severe infections, which can then lead to the brain becoming inflamed. HSV-1, however, is now causing an increasing amount of genital infections due to hygienic advancements in wealthy nations. The WHO additionally discovered 417 million people between the ages of 15 and 49 have HSV-2. This form of the disease is usually sexually transmitted, whereas HSV-1 is largely the result of skin-to-skin contact or the sharing of objects that have touched infected skin, Daily Mail reports. Carriers of HSV-2 are also more likely to catch or spread HIV, but there does not appear to be a link between HSV-1 and the AIDS-causing virus.
There is currently no cure for either form of herpes, and many carriers do not show symptoms. Nathalie Broutet, a WHO medical officer, said trials are currently underway to test the effectiveness of therapeutic and preventative vaccines. We really need to accelerate the development of vaccines against herpes simplex virus, and if a vaccine designed to prevent HSV-2 infection also prevented HSV-1, it would have far reaching benefits. A vaccine previously tested by pharmaceutical giant GlaxoSmithKline yielded some success in combating HSV-1, Gottlieb added.

You may never know who may be infected, as around 3.7 billion worldwide people have herpes and not all of them present with outside symptoms. While HSV-1 causes orolabial herpes (cold sores) around the mouth, HSV-2 causes genital herpes, which is easily transmitted through intercourse. This may lead to further spreading, especially for HSV-1, transmitted through simple mouth-to-mouth contact or kissing.
According to their tests, WHO has found that 67% of the world?s population under 50 years old has one type of herpes virus.
The incredibly high numbers have raised alarms for better awareness campaigns against sexually transmitted diseases (STDs), but also for a possible solutions. According to Sami Gottlieb, a medical officer for WHO, there is a need to accelerate the development of proper methods to combat all herpes simplex viruses.
Partnerships have formed in order to develop new ways to either prevent or fully treat the virus infection. Tuesday’s federal budget will include funding for a $15m for a national carp control plan in an attempt to eradicate Australia’s worst freshwater feral pest, the government announced on Sunday. The plan includes the staged release of the carp-specific herpes virus in the Murray-Darling basin. The virus affects the carp’s skin and kidneys, takes about seven days to have a noticeable effect and, once it takes hold, usually kills the fish within 24 hours.
A joint ministerial taskforce will finalise the national plan and includes the minister for industry, innovation and science, Christopher Pyne, the deputy prime minister, Barnaby Joyce, and the minister for the environment, Greg Hunt.
Joyce said the economic impact of carp was estimated at $500m a year, mostly in regional Australia, and especially along the Murray River. The prevalence of HIV infection among adults aged 18-49 years residing in households in the United States was 0.47% for the period 1999-2006. Infection with HSV-2 was significantly associated with HIV infection among the total population aged 18-49 years and especially so among the non-Hispanic black population.
In 1999-2006, nearly one-quarter of HIV-positive individuals but only 1% of the HIV-negative individuals aged 18-49 years had low CD4 counts (a marker of decreased immune function).
Measurement of HIV prevalence in a nationally representative sample of the United States population provides an understanding of the background level of infection in the general household population aged 18-49 years as well as in demographic subgroups. Herpes simplex-virus type 2 (HSV-2) infection is associated with HIV infection; some studies have shown that HSV-2 infection doubles the risk of HIV acquisition (3-5).


In 1999-2006, the prevalence of HIV infection among adults aged 18-49 years in the civilian noninstitutionalized household population of the United States was 0.47%. Adults aged 40-49 years were more likely to be HIV positive compared with those aged 18-29 years. In 1999-2006, the non-Hispanic black population had an increased prevalence of HIV infection compared with other population subgroups.
HIV status was associated with HSV-2 infection, especially among the non-Hispanic black population.
The higher risk of HIV infection among those HSV-2 positive was especially true for non-Hispanic blacks, where the HIV prevalence was 3.69% among HSV-2 positive non-Hispanic blacks. How does the immune function of HIV-positive individuals compare with HIV-negative individuals? HIV positivity: Presence of antibody to human immunodeficiency virus (HIV) in blood or urine (6). CD4 counts: Enumeration of CD4 T-lymphocytes (also called T-helper cells, a measure of immune function) in blood (7).
HSV-2 positivity: Presence of antibody to Herpes simplex virus type-2 (HSV-2) in blood (6,8-10). National Health and Nutrition Examination Surveys (NHANES) data were used for these analyses.
The NHANES sample is selected through a complex, multistage design that includes selection of primary sampling units (counties), household segments within the counties, and finally sample persons from selected households. Sample weights, which account for the differential probabilities of selection, nonresponse and noncoverage, are incorporated into the estimation process (12).
The relative standard error (RSE), defined as the estimate divided by its standard error, is an indicator for statistical reliability. The data files for this report were prepared in the Division of Health and Nutrition Examination Surveys, Informatics Branch.
The World Health Organization (WHO) in its first estimate of the global prevalence of the highly infectious herpes virus showed that almost two-third of the world’s population under the age of 50 has the disease. According to the study, there are two types of herpes the herpes simplex virus type 1 (HSV-1), and the HSV-2, which causes genital herpes. HSV-1 normally causes mouth ulcers rather than genital infection, but according to the study, it has also become an increasing cause of genital infection majorly in the rich countries.
As per the study, HSV-2 can increase the risk of catching and spreading HIV, the disease that causes AIDS. Nathalie Broutet, a WHO medical officer, said in a statement that US National Institutes of Health and companies, including GlaxoSmithKline (GSK), are busy carrying out trials to find out if any therapeutic or preventive vaccine was preferable.
GSK earlier abandoned a vaccine trial after finding the product was not effective against HSV-2, although it showed some efficacy against HSV-1, said Dr Gottlieb. These improvements lowered the risk of catching HSV-1 during childhood and, thus, increased the risk of youths catching it when they begin engaging in oral sex later on. However, research found that the latter, more often overlooked HSV-1, may ultimately lead to HSV-2 and present with increased risk of becoming infected with HIV.
Marleen Temmerman, from WHO?s Department of Reproductive Health and Research, both are ?highly infectious and incurable?.
It may be recognized as a condition that developed during childhood for some, and then never reappeared again.
The simple fact that HSV-1, which is very common, can turn into HSV-2, is severely worrying.
It would first require study to understand which action would be more appropriate, considering symptoms don?t always occur. CSIRO scientists have been testing the virus in Australian native fish species and other animals found along the river for the past seven years and have established that it is safe to release into the ecosystem without harming other species. Approximately one-third of HIV-positive persons had healthy immune systems as compared with 90% among those HIV negative. This information can also be used to monitor trends in infection in the household population over time. Estimates of the prevalence of both HSV-2 and HIV infection can provide further understanding of the risk of HIV infection in higher risk subgroups of the general household population.
Among HIV-infected individuals, measurement of CD4 counts is often used to demonstrate how well anti-HIV drugs are working. The immune function among HIV-infected individuals is often different from HIV-negative individuals.


NHANES is a cross-sectional survey designed to monitor the health and nutritional status of the civilian, noninstitutionalized U.S. The sample design includes oversampling in order to obtain reliable estimates of health and nutritional measures for population subgroups. The standard errors of the percentages were estimated using Taylor Series Linearization in SUDAAN, a method that incorporates the sample weights and sample design (13).
To examine possible predictors of HIV positivity, differences in prevalence were evaluated by examining P-values calculated using a univariate t-statistic obtained from a general linear contrast procedure in SUDAAN. HIV infection in the United States household population aged 18-49 years: Results from 1999-2006. Update on the seroepidemiology of human immunodeficiency virus in the United States household population: NHANES III, 1988-1994. Risk of human immunodeficiency virus infection in herpes simples virus type 2 persons: a meta-analysis.
National Health and Nurtition Examination Survey III: Weighting and examination methodology.
The study showed that improved hygiene in rich countries is lowering HSV-1 infection rates in childhood, putting young people at higher risk of catching the disease via oral sex. Sami Gottlieb, a WHO medical officer, said, “We really need to accelerate the development of vaccines against herpes simplex virus, and if a vaccine designed to prevent HSV-2 infection also prevented HSV-1, it would have far reaching benefits”. It’s the go-to joke whenever one of your friends gets a cold sore, and then there are those awful Valtrex commercials that seem to propose that rock climbing or whatever is the way to remain outbreak-free. The unfortunate fact that hinders research is that herpes does not always cause symptoms or any sort of sign for a majority of the population.
Regardless, WHO is working on a solution, and will be presenting new strategies against the disease in 2016, at their annual World Health Assembly.
Other public health surveillance systems address the impact of HIV infection among high risk groups including the homeless and prisoners that are not included in surveys of the general household population (1,2). Estimates of this measure in the general population can provide a picture of health among HIV-infected individuals. In 1999-2006, African Americans, Mexican Americans, persons with low income, persons 12-19 years of age, and persons 60 years and older were oversampled. Ninety-five percent confidence intervals were estimated by using the logit transformation (14). All estimates whose RSE was greater than a cut point of 40% are designated with a footnote to indicate that the estimate is statistically unreliable.
And yet, herpes is approaching something of epidemic proportions, according to the World Health Organization. Information on risk factors for HIV infection, such as sexual activity and intravenous drug use, were not addressed in this analysis, but are collected as part of the NHANES survey. The survey consists of interviews conducted in participants' homes, standardized physical examinations conducted in specially outfitted mobile examination centers, and laboratory tests utilizing blood and urine specimens provided by participants during the physical examination. In addition, estimates based on fewer than 10 positive persons are also designated with a footnote to indicate statistical unreliability (16). Researchers studied the frequency of herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2). Each year of data collection is based on a representative sample covering all ages of the civilian, noninstitutionalized population. Both diseases are more common than previously believed, and as it turns out, one can lead to the other. This adjustment enabled us to compare prevalence estimates between subgroups that differ with respect to their age distributions (15).
The WHO says that due to advancements in health and hygiene, fewer people are contracting HSV-1 in childhood.
That means that they’re at greater risk of contracting it genitally through oral sex as they mature.
Unless you go to the doctor with an open sore near your mouth, they’re unlikely to screen for it.
