Myths vs facts on genital herpes (HSV-2) & cold sores
Individuals who reactivate the virus without visible symptoms still release the virus in the oral or genital tract. Asymptomatic viral shedders are at risk of unknowingly simplexx the virus to partners. Virus type Researchers have found that people with HSV-2 genital herpes tend to have more shedding than those with HSV-1 genital herpes.
This of course will decrease over time as well. Duration of infection The rate of shedding decreases over time.
People with new infections are more likely to shed the virus than those with an infection more than a year old. Transfe of recurrences Rate of asymptomatic shedding of HSV also related to frequency of recurrences of genital herpes. People with frequent recurrences may shed the virus more often, but this is still an area being studied.
Herpes Virus HSV-1 and HSV-2 Transmission and Transmissibility
Neural tissue transport of herpes simplex virus results in life-long latent infection. HSV remain in the body for life, hidden in a dormant state inside nerve cells. The virus escapes the usual immune response by simpled nerve fibres. As the immune system moves in to control the infection, the virus conceals itself within nerve cells. The virus is carried to the nerve "cell body" in a swelling called a ganglion located close to the spinal cord.
It remains there, hidden within the nerve cell and in an inactive state, for the lifetime of the infected individual. Retrograde transport through adjacent neural tissue to sensory ganglia leads to lifelong latent infection.
Tenital reactivated, the virus is transported by the neuron back to the epithelium, where more replication occurs, and another outbreak ensues. Symptoms of genital herpes can vary in appearance and intensity. Some people have no symptoms or such mild symptoms that they don't suspect they have an infection. For others, the first episode of herpes primary infection can genotal one or more very painful lesions to erupt on the skin.

Reactivating from there, HSV-1 causes viral shedding and outbreaks on lips, nose, oral mucosa, and sometimes other parts of the face.
HSV-2 usually establishes latency in the sacral ganglion at the base of the spine. Reactivating from there, HSV-2 causes viral shedding and outbreaks on genital area, buttocks, and rarely other body parts below the waist. Oral HSV-2 although possible, occurs very rarely. First-episode manifestation Primary oral infection with HSV-1 usually causes gingivostomatitis mainly in children and herpetic pharyngitis mainly in adolescents and adults.
HSV can be transmitted through the following activities: Penile-vaginal intercourse Anal intercourse Oral-genital sexual contact Any mucous membrane to mucous membrane contact e.

It's also the reason herpes both HSV-1 and HSV-2 can pose serious challenges for infants, who have a limited immune response.
How long herpes person has had the infection. It is not clear why a decrease of can reactivation transfer over time, but is believed to be due to the buildup of antibodies in the infected persons system. Tarnsfer people diagnosed with HSV-2 affecting the genital area typically have four hwrpes five genital recurrences the simplex year. After the first year, most people have fewer and milder recurrences, lasting a week or less.

Inamong people between ages 14 and 49, the prevalence of HSV-2 was 12 percent, compared with 18 percent in This means that about 1 in 8 people in this age range had HSV HSV-1 prevalence also declined during those years, from 59 percent in to 48 percent in Taking a global look at the numbers, in67 percent of the people in the world who were younger than 50 had an infection caused by herpes simplex virus type 1 HSV-1says the World Health Organization WHO.Nevertheless, either type can infect both oral and genital areas. Genital herpes can be caused by both HSV-1 and HSV And signs and symptoms of initial genital herpes caused by HSV-1 or HSV-2 are indistinguishable. However, subsequent recurrences are more frequent with HSV Oral HSV-2 although possible, occurs very rarely. Fact about herpes: Herpes is very common and may be caused by both herpes simplex type 1 and herpes simplex type 2 (HSV-1 or HSV-2). HSV-1 causes "cold sores" on the mouth, and up to 80% of the population has this virus. However, it may also be transmitted to the genitals through oral-genital sex and about 40% of genital herpes is caused by HSV While genital herpes is usually associated with herpes simplex 2 (HSV-2), it can also be caused by herpes simplex 1 (HSV-1). HSV-2 is more likely to cause symptoms and to be transmitted during sex.
That adds up to more than 3. HSV-1 is mainly transmitted by oral-oral contact. It usually causes cold sores, also known as orolabial herpeson or near the mouth.
HSV-1 is also an important cause of genital herpes. Around million people between the ages of 15 and 49 years have a genital HSV-1 infection. Most live in the Americas, Europe, and the Western Pacific.
Fewer people in wealthy, industrialized countries are developing HSV-1 infections as children, probably as a result of better hygiene and living conditions. In such countries, people are instead at risk of contracting a genital HSV-1 infection through oral sex.
The emotional impact of being diagnosed with genital herpes is often much worse than the condition and it doesn't deserve the upset it causes. District Health Boards DHBs are responsible for providing or funding the provision of health services in their district.
