How Long Does It Take For Herpes To Show Up After Exposure
Herpes is not just one type of infection. Its a family of related viruses that can cause several different medical conditions. The herpes infection were talking about when it comes to sex is caused by the herpes simplex virus or HSV .
Typically, HSV-1 is responsible for cold sores on the lips and around the mouth. HSV-2 is most commonly transmitted sexually and causes genital herpes, a common sexually transmitted infection . However, HSV-1 can also spread from the mouth to the genitals through oral sex and cause genital herpes.
While the symptoms of herpes usually show up anywhere from a couple of days to about two weeks following exposure, thats not always the case. In some cases, you may be asymptomatic for weeks or months before your first outbreak .
Long story short, if a few weeks have gone by after exposure and you dont have any symptoms, that doesnt necessarily mean youre out of the woods.
Black And Hispanic Communities And Genital Herpes
Black Americans and Hispanic Americans have higher rates of STDs generally when compared with white Americans. This isnt because of ethnicity or race instead, social conditions such as poverty, lack of access to healthcare, and fear of discrimination from doctors and other healthcare providers all play part in the disparity.
What Is The Difference Between Genital Herpes And Genital Warts
Both genital herpes and genital warts are STIs, are spread through skin-to-skin contact, and are caused by a virus. But the viruses that cause genital herpes and genital warts are different:
- Herpes simplex virus is the virus that causes genital herpes.
- Human papillomavirus is the virus that causes genital warts.
There is no cure for either genital herpes or genital warts. But, different medicines can help manage the symptoms of herpes and treat the complications of HPV infections that can cause genital warts.

Ruling Out Conditions That Resemble Oral Herpes
Canker Sores
Simple canker sores are often confused with the cold sores of HSV-1. Canker sores frequently crop up singly or in groups on the inside of the mouth, or on or underneath the tongue. Their cause is unknown, and they are common in perfectly healthy people. They are usually white or grayish crater-like ulcers with a sharp edge and a red rim. They usually heal within 2 weeks without treatment.
This aphthous ulcer is located in front of and just below the bottom teeth.
Thrush
Oral candidiasis is a yeast infection that causes a whitish overgrowth in the mouth. It is most common in infants, but can appear in people of all ages, particularly people taking antibiotics or those with impaired immune systems.
Other conditions that may be confused with oral herpes include herpangina , sore throat caused by strep or other bacteria, and infectious mononucleosis.
What Is Herpes Ii
Herpes II is a sexually transmitted viral infection, which often produces painful sores, usually in the genital area. Once infected, an individual may carry the virus and be subject to recurrent bouts of infection. Some estimate that as many as 20 percent of the adult population in the United States has been exposed to the virus.

What Are The Complications Of Genital Herpes
Genital herpes may cause painful genital ulcers that can be severe and persistent in persons with suppressed immune systems, such as HIV-infected persons. 5 Both HSV-1 and HSV-2 can also cause rare but serious complications such as aseptic meningitis . 5 Development of extragenital lesions may occur during the course of infection. 5
There are also potential complications for a pregnant woman and her newborn child. See How does herpes infection affect a pregnant woman and her baby? below for information about this.
Herpes Encephalitis And Meningitis
Herpes Encephalitis
Herpes simplex encephalitis is inflammation of the brain caused by either HSV-1 or HSV-2. It is a rare but extremely serious brain disease. Untreated, herpes encephalitis is fatal most of the time. Respiratory arrest can occur within the first 24 to 72 hours. Fortunately, rapid diagnostic tests and treatment with acyclovir have significantly improved survival rates and reduced complication rates. Nearly all who recover have some impairment, ranging from very mild neurological changes to paralysis.
Herpes Meningitis
Herpes simplex meningitis is inflammation of the membranes that line the brain and spinal cord. It is mainly caused by HSV-2. Like encephalitis, meningitis symptoms include headache, fever, stiff neck, vomiting, and sensitivity to light. Fortunately, herpes meningitis usually resolves after about a week without complications, although symptoms can recur.

If You Have Genital Herpes Already Can It Be Spread To Other Parts Of The Body Such As The Arms Or Legs
No. Genital herpes cannot be transmitted to another part of your body such as your arm, leg or hand after the first infection occurs. If you have genital HSV II, you will not get HSV II at another site in your body. The immune system produces antibodies that protect other parts of your body from infection. However, there are cases where a person has multiple site infections from the same virus. This is usually acquired at the time of the first infection. For example, if someone has never had herpes but then has oral and genital sex with an infected partner, they can acquire the infection at both sites.
Onset Of First Outbreak
The first outbreak of oral herpes usually develops within about one to three weeks after infection. This initial outbreak may last for up to three weeks.
With genital herpes, the first outbreak usually occurs within about two to 20 days. Similar to oral herpes, the initial outbreak may last as long as three weeks.

Most Outbreaks Occur Within Two Weeks Of Herpes Exposure
If youve been infected with herpes and are symptomatic, youll usually start to experience some effects of the virus within one to two weeks.
An initial herpes outbreak usually lasts for two to three weeks and involves a range of different symptoms. Many people with herpes note that the initial outbreak has the worst symptoms and that subsequent outbreaks are less severe, although this isnt always the case.
Most people start to become aware that they might have herpes after a tingling sensation starts to develop in the area affected by the virus. For oral herpes, this is the start of the development of oral cold sores for genital herpes, the sores develop on the genitals, thighs and buttocks.
For more information on spotting an outbreak, check out our guide on Herpes or Ingrown Hair? How to Tell The Difference.
Over the course of two to three weeks, this tingling/itching feeling leads to the development of blisters. The blisters eventually open into sores, then dry out and heal. Most herpes outbreaks do not leave any permanent scarring.
During your first herpes outbreak, you might also experience flu or cold-like symptoms. About 70% of women and 40% of men experience some level of flu-like symptoms, such as muscle pains, gland swelling, headaches and fever.
Causes And Risk Factors Of Genital Herpes

Two types of viruses cause genital herpes herpes simplex type 1 and herpes simplex type 2 .
Usually, HSV-1 causes oral herpes, which becomes visible in the form of cold sores, or fever blisters, on the face, close to the mouth. Most people contract an oral herpes infection during their childhood or young adult years from nonsexual contact with the saliva of an infected person.
HSV-1 mainly spreads through direct contact with cold sores or saliva. Having oral herpes, or cold sores, does not mean that you have genital herpes. But if you have oral herpes, you can spread it from your mouth to another persons genitals if you perform oral sex on them.

Genital Herpes And Pregnancy
Women with herpes before pregnancy can usually expect to have a healthy baby and a vaginal delivery.
If you have genital herpes during pregnancy, there’s a risk your baby could develop a serious illness called neonatal herpes.
This can be fatal, but most babies recover with antiviral treatment.
The risk of your baby getting neonatal herpes is low if you have had genital herpes before.
It’s higher if you get genital herpes for the first time in pregnancy.
Herpes And Newborn Infants
Herpes infection in a newborn can cause a range of symptoms, including skin rash, fevers, mouth sores, and eye infections. If left untreated, neonatal herpes is a very serious and even life-threatening condition. Neonatal herpes can spread to the brain and central nervous system, causing encephalitis and meningitis. It also can lead to intellectual disability, cerebral palsy, and death. Herpes can also spread to internal organs, such as the liver and lungs.
Infants infected with herpes are treated with acyclovir, an antiviral drug. They usually receive several weeks of intravenous acyclovir treatment, often followed by several months of oral acyclovir. It is important to treat babies quickly, before the infection spreads to the brain and other organs.

How Common Is Genital Herpes
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
How Do People Get Genital Herpes
Infections are transmitted through contact with HSV in herpes lesions, mucosal surfaces, genital secretions, or oral secretions. 5 HSV-1 and HSV-2 can be shed from normal-appearing oral or genital mucosa or skin. 7,8 Generally, a person can only get HSV-2 infection during genital contact with someone who has a genital HSV-2 infection. However, receiving oral sex from a person with an oral HSV-1 infection can result in getting a genital HSV-1 infection. 4 Transmission commonly occurs from contact with an infected partner who does not have visible lesions and who may not know that he or she is infected. 7 In persons with asymptomatic HSV-2 infections, genital HSV shedding occurs on 10.2% of days, compared to 20.1% of days among those with symptomatic infections. 8

Tips For Managing Herpes Symptoms
The symptoms of herpes can be painful and uncomfortable. Fortunately, there are a few things you can easily do at home to help ease these symptoms, including:
- Apply an ice pack or warm compress to the affected area.
- Take over-the-counter pain relievers, such as acetaminophen.
- Keep the affected area clean and dry to reduce the risk of infection.
- Avoid tight clothing that may irritate genital sores.
- Dont pop blisters or pick at scabs that form over the sores.
- Ask your healthcare provider to recommend a painkilling cream.
Taking proper care of your skin and overall health while experiencing an outbreak can help to prevent complications like infection and assist in faster healing for your sores. Keep in mind that you are especially contagious during an outbreak, so its best to avoid intimate contact, such as kissing or sex, until the sores heal.
Episodic Therapy For Recurrences

For a recurrent episode, treatment takes 1 to 5 days, depending on the type of medication and dosage. You should begin the medication as soon as you notice any signs or symptoms of herpes, preferably during the prodrome stage that precedes the outbreak of lesions.
In order for episodic therapy to be effective, it must be taken no later than 1 day after a lesion appears. If taken during prodrome, episodic therapy may help prevent an outbreak from occurring or reduce its severity. If taken at the first sign of a lesion, it can help speed healing.

How Is Genital Herpes Diagnosed
HSV nucleic acid amplification tests are the most sensitive and highly specific tests available for diagnosing herpes. However, in some settings viral culture is the only test available. The sensitivity of viral culture can be low, especially among people who have recurrent or healing lesions. Because viral shedding is intermittent, it is possible for someone to have a genital herpes infection even though it was not detected by NAAT or culture. 11
Type-specific virologic tests can be used for diagnosing genital herpes when a person has recurrent symptoms or lesion without a confirmatory NAAT, culture result, or has a partner with genital herpes. Both virologic tests and type-specific serologic tests should be available in clinical settings serving patients with, or at risk for, sexually transmitted infections. 11
Given performance limitations with commercially available type-specific serologic tests , a confirmatory test with a second method should be performed before test interpretation. If confirmatory tests are unavailable, patients should be counseled about the limitations of available testing before serologic testing. Healthcare providers should also be aware that false-positive results occur. In instances of suspected recent acquisition, serologic testing within 12 weeks after acquisition may be associated with false negative test results. 11
Providers are strongly encouraged to look at CDCs STI Treatment Guidelines for further diagnostic considerations.
Research And Statistics: Who Has Genital Herpes
Its estimated that each year, 776,000 people in the United States get new genital herpes infections. Genital herpes is most often caused by herpes simplex virus type 2 .
According to data from the National Health and Nutrition Examination Survey , the prevalence of HSV-2 was 11.9 percent during 2015 and 2016, a decline of 5.9 percentage points from the years 1999 and 2000.
HSV-2 is more common in women than in men. Its suspected that women are more likely to contract the HSV-2 infection because genital infection is more easily transmitted from men to women than from women to men during penile-vaginal sex.

Duration Of Genital Herpes
The first episode of genital herpes usually begins with inflammation, followed by a small group of blisters that break and weep after a few days and eventually crust over and heal. The first outbreak is usually the worst and ends within about three weeks. The CDC recommends antiviral medication for everyone having a first outbreak of genital herpes.
After the initial outbreak, outbreaks tend to last for less time and have less severe symptoms. Research has indicated that the number of symptomatic outbreaks may decrease over time.
