What Are The Chances Of Catching Herpes

How Common Is Genital Herpes

Sexually transmitted diseases STD in women and men syphilis, chlamydia, gonoirrhoeae and hermes

Genital herpes infection is common in the United States. CDC estimated that there were 572,000 new genital herpes infections in the United States in a single year.1 Nationwide, 11.9 % of persons aged 14 to 49 years have HSV-2 infection .2 However, the prevalence of genital herpes infection is higher than that because an increasing number of genital herpes infections are caused by HSV-1. 3 Oral HSV-1 infection is typically acquired in childhood because the prevalence of oral HSV-1 infection has declined in recent decades, people may have become more susceptible to contracting a genital herpes infection from HSV-1. 4

HSV-2 infection is more common among women than among men the percentages of those infected during 2015-2016 were 15.9% versus 8.2% respectively, among 14 to 49 year olds. 2 This is possibly because genital infection is more easily transmitted from men to women than from women to men during penile-vaginal sex. 5 HSV-2 infection is more common among non-Hispanic blacks than among non-Hispanic whites . 2 A previous analysis found that these disparities, exist even among persons with similar numbers of lifetime sexual partners. Most infected persons may be unaware of their infection in the United States, an estimated 87.4% of 14 to 49 year olds infected with HSV-2 have never received a clinical diagnosis. 6

The age-adjusted percentage of persons in the United States infected with HSV-2 decreased from 18.0% in 19992000 to 12.1% in 2015-2016. 2

No Sex When Genital Lesions Are Visible

It is important to know that the symptomatic herpes simplex virus is highly contagious. Thatâs why if one partner is herpes-positive, abstinence is a must during times when he or she has genital ulcers.7 This is true for oral sex if the herpes-positive partner has visible symptoms near the mouth.9 However, the absence of visible ulcers or blisters does not guarantee full protection from infection and there is still some probability of genital herpes transmission.7

How Herpes Is Transmitted

Active sores leaking fluid that contains the virus are more likely to spread the infection. But the virus can be transmitted even outside of an active outbreak.

Some show symptoms when they contract the virus or a few months or years down the line. But not everyone shows symptoms: The virus can lie dormant in the body for years without causing an outbreak.

There are periods during the herpes virus outbreak cycle when the virus is more likely to spread. This includes when:

  • the area of infection begins to feel itchy and uncomfortable
  • sores are leaking fluid or otherwise open or moist

Other myths exist about how herpes spreads. Here are some of the facts:

  • Herpes can spread even without the presence of active sores.
  • The herpes virus can be present even without symptoms once you contract herpes, the virus is in your body for life.
  • Herpes can be transmitted through kissing, even if the kiss doesnt involve any tongue.

Use Of Per Coital Act Probability Data To Estimate Viral Particle Infectivity Parameter

We fitted our model in a bidirectional fashion given uncertainty regarding both biological and epidemiological parameters of HSV-2 transmission: while per particle viral infectivity is relatively poorly defined and can only be estimated in vivo with mathematical modelling , per act transmission probability can also only be projected within a certain range from available epidemiological data , and may vary between different populations. We therefore used estimates for the median number of acts prior to transmission to arrive at a value for viral infectivity, and then used an estimate of viral infectivity to estimate number of acts prior to transmission, to see if these processes produced consistent results.

How Effective Is Medication At Preventing Infection

Iâm almost positive I have HSV

If you have genital herpes, you will probably be somewhat less likely to infect your partner if you use antiviral medication for prevention. The medications used for this purpose include aciclovir, famciclovir and valaciclovir. They must be taken every day over a long period of time, though. One study showed that over a period of eight months,

  • 4 out of 100 people became infected when the partner with the virus took a placebo, and
  • 2 out of 100 people became infected when the partner with the virus took antiviral medication every day.

These couples were also advised to use condoms as well but many didn’t use them consistently. So its not clear whether taking antiviral medication can lower the risk of infection even further if you always use condoms anyway, or whether using condoms is just as effective on its own.

Whether or not you would like to use preventive medication is ultimately an individual decision. Many factors can play a role, such as how long you or your partner have had the infection, how frequent and severe the outbreaks are, whether you are male or female, the frequency of sexual contact and whether you use condoms.

Myth #: Your Sex Life Is Over

While theres no cure, herpes treatment is simple and can shorten or prevent outbreaks, so you can still have a love life.

People have a disproportionate fear of herpes in relation to any other STI, Grimes says. They feel like their sex lives are ruined forever and thats in no way the case.

If you have the virus, your doctor may prescribe a medication like Zovirax or Valtrex to keep on hand in case of a flare-up. And if you experience outbreaks often, your provider may recommend daily dosing. However you treat it, its worth remembering that herpes is a condition to manage it doesnt define you.

If you have to be perfect for your new partner, that partner will be looking a very, very long time to find a match! Grimes says. Everyone has something, and since one in six Americans between 14-49 have HSV-2, odds are very high that your next partner is in the same boat. The main issue is to have productive conversations around these issues.

So theres no reason for all the stigma and secrecy surrounding herpes, since its safe to assume more people have it than you think. And if youre diagnosed with the virus, your provider will help you find a treatment plan thats easy, effective, and fit for your lifestyle.

Can You Get Herpes From Oral Sex

There are two types of herpes, both of which are common manageable infections that can be contracted through oral sex. Herpes simplex virus type 1 is more commonly associated with oral herpes, and HSV-2 is typically associated with genital herpes. However, both strains can cause oral herpes if your mouth comes into contact with the virus, and both strains can cause genital herpes as well. Learn more about HSV-1 and HSV-2 so you can better understand how transmission happens and what you can do to protect yourself and your partner.

What You Need To Know

  • Herpes simplex virus , also known as genital herpes, is most likely to be spread when an infected person is having an outbreak, but it can also be transmitted without any symptoms being present.
  • Medications can help reduce your symptoms, speed up the healing of an outbreak and make you less contagious.
  • If you know you have genital herpes before becoming pregnant, your physician will monitor your condition throughout your pregnancy. If you have an active outbreak at the time of delivery, cesarean section may be recommended.

How Do You Get Herpes Causes And Risk Factors

Sexual Health – Herpes

Herpes infections are caused by herpes simplex virus types 1 and 2. These contagious viruses are spread through skin-to-skin contact with a person who is having a herpes outbreak.

You get herpes by touching a herpes sore or the skin, lips, genital fluids, or saliva of a person with an oral or genital herpes infection. Herpes can be spread even when there are no visible blisters or sores.

This article discusses how herpes is spread. It also explains who is at high risk for herpes and how you can protect yourself.

The chances of getting herpes from sharing a drink with someone who has herpes even an active outbreak of herpes is next to zero.

While its unlikely youll contract herpes by sharing drinks, its always a good rule of thumb to avoid sharing glasses, dishware, or other objects, like towels or silverware, with someone you dont know or with someone you know has herpes.

What Are The Risks Associated With Shingles

Some people experience pain around the rash site for a month or morepain that is severe enough to interfere with daily activities.

Scratching the rash can also cause a secondary infection if harmful bacteria get into the sores.

Shingles on the face can involve the eyes, which is serious because it can cause scarring and blindness.

The occurrence and severity of shingles and its complications increase with age.

The Effectiveness Of Condom Protection In Homosexual Contact

According to a 2010 study by Emily T. Martin and her colleagues, being homosexual does not significantly alter the effectiveness of condom protection against herpes acquisition. Therefore, the probability of contracting herpes during protected sex is approximately the same for homosexual and heterosexual persons.1

In theory, oral HSV1 is the most easily acquired infection, because it is usually the first herpes simplex type someone encounters, and it is commonly spread by social kissing among relatives and friends. Children who have no prior infections with an HSV type do not have an acquired immune response and are most susceptible.

50% of Americans, by their teenage and young adult years, will have acquired HSV1 and will have the HSV1 antibodies, and by the time they reach age 50, 80-90% of Americans will have acquired HSV1.

In contrast, almost all HSV2 infections are encountered during teenage and adult years, once someone has become sexually active.

The Risk For Males And Females Is Different

It has been proven that males are more susceptible to protected herpes transmission. This is because heterosexual females primarily get infected by the herpes simplex virus through penile skin, which is covered by a condom during protected sexual intercourse.2

On the other hand, heterosexual males may get this infection from contact with a wider surface area, including the vulva and perineum.4

How Can I Make Sure I Dont Give Anyone Herpes

If you find out that you have herpes, try not to freak out. There are a few ways that you can stop it from spreading to your partners and other parts of your body.

  • Talk with your doctor about taking herpes medication every day, which can lower your chances of spreading herpes.

  • Dont have sex during a herpes outbreak, even with a condom. There may be sores on places the condom doesnt cover.

  • Learn how to tell when an outbreak is coming, and stop having sex right when you notice these signs. You may feel a burning, itching, or tingling feeling that lets you know youre about to get sores.

  • Dont have sex until your sores are totally gone, and the scabs heal and fall off.

  • Dont touch your herpes sores, because you can spread the infection to other parts of your body or other people. If you touch a sore, wash your hands with soap and water right after.

  • Dont wet contact lenses with spit this might spread your oral herpes to your eye.

  • If you have a cold sore on your mouth, don’t kiss anyone especially babies, children, or pregnant women.

  • Always tell your sexual partners that you have herpes before you have sex, so you can work together to prevent it from spreading. Telling someone you have an STD can be hard, but herpes is super common and doesnt lead to serious health problems. So try not to be too embarrassed or stressed out about it.

Genital Herpes: How Can You Prevent The Spread Of Herpes In Sexual Relationships

Herpes viruses are most likely to be transmitted during an outbreak, so it’s better to not have sex during this time. Herpes can also be passed on to others in symptom-free phases, though. This risk can be reduced considerably by using condoms.

If you have genital herpes, there are some things you can do on your own to protect your partner from infection. The main things are

  • not having sex during an outbreak,
  • using condoms during symptom-free phases, and
  • talking openly with your partner about the disease.

Preventive treatment with antiviral medication may be an option for people who have genital herpes very frequently. This medication inhibits the activity of the virus, thereby lowering the risk of infecting partners.

Genital Herpes’ Silent Spread

Herpes simplex (Cold sore): All you need to know

The finding comes from a large study that collected daily genital swabs from nearly 500 people infected with herpes simplex virus type 2 , the genital herpes virus. Many thought they were uninfected, but found out they were herpes carriers when they underwent blood tests.

It’s not too hard to find people who carry the virus, as 16% of Americans have HSV-2 infections. The vast majority — between 75% and 90% — don’t know they are infected because they don’t get, or don’t notice, herpes sores on their genitals.

These asymptomatic herpes carriers shed infectious virus 10% of the 30 or more days they were in the study, report University of Washington researcher Anna Wald, MD, MPH, and colleagues. And nearly all the time, these people had no obvious sign of herpes infection while they were actively shedding virus.

“The primary concern of many HSV-2-seropositive persons is the risk of transmission to sexual partners in our experience this is the main source of angst in patients with genital herpes,” Wald and colleagues note in the April 13 issue of the Journal of the American Medical Association.

Asymptomatic-infected people shed herpes virus only about half as often as do people who have herpes symptoms. But when they are shedding virus, they shed just as much as people who have frequent symptoms .

What If My Partner Already Has Herpes Simplex

When you and your partner have the same virus you will not reinfect each other even on a different part of the body, you will not catch it back yourself on a different part of your body.

If you have caught a genital infection from a partners genitals, they will not catch the virus back on their face.

If you have caught a genital infection from a partners facial cold sores, they will not catch the virus back on their genitals.

And also:

If you have caught it on your face from your partners genitals, then they will not catch it on their face if they do oral sex on you.

Quantitative Viral Load And Transmission

We recorded genital viral load during each simulated coital act during 1536 transmissions at varying levels of infectivity. At medium infectivity, the median log10 genital viral load during 512 coital acts that resulted in transmission was 7.0 and during 2777 coital acts without transmission was 4.5 . Therefore, 16% of coital acts during shedding resulted in transmission. Only three transmissions occurred with less than 105 HSV DNA copies and none occurred with less than 104 HSV DNA copies . Ninety-six per cent of transmissions occurred at more than 106 HSV DNA copies. At low infectivity, median log10 genital viral load during 512 coital acts with transmission was higher: 7.3 and only one transmission occurred at less than 105 HSV DNA . At higher infectivity, median genital viral load during coital acts with transmission was lower: 6.4 and 2% of transmissions occurred at less than 105 HSV DNA .

For all three infectivity estimates, we divided HSV DNA copy number at coitus into strata separated by 0.1 log and measured per coital act risk of transmission within each stratum: there was a rise in transmission risk with increase in genital tract viral load . We fitted locally weighted scatterplot smoothing smooth curves to the transmission estimates for each infectivity parameter, thus allowing estimates of transmission risk for each level of shedding. With medium infectivity, 50% per coital act transmission was predicted for 6.7 log HSV DNA copies .

Could I Pass Herpes Simplex To A Partner If I Have No Symptoms

This sometimes happens but is not likely. When the virus is inactive inside the nerve cells it cannot be caught by a partner. If there is virus on the skin surface where you get your symptoms, it may be passed on.

Before the outbreak begins, there may be a tingly or itchy feeling at the place where this will happen. This means that diagnosed people are less likely to pass it on when there is nothing to see on the skin, because they are usually more aware of these prodromes , whereas undiagnosed people often ignore highly infectious and obvious symptoms, because they do not know what they are. This is not asymptomatic as you can feel something and you should not have sex at this time.

Asymptomatic shedding means without sensation and a scientific test can virus on the skin when the person feels nothing. This applies to type 2. Type 1 doesnt like the genital region and is less likely to recur and to shed asymptomatically. This happens only in some people, mostly in the first six months. After a year or two, if a person is not having many outbreaks, they will rarely have virus on the skin without symptoms.
