How Is Herpes Transmitted
Herpes simplex is highly contagious. It is primarily transmitted via contact with an infected person, either with saliva or through direct contact with fluids from herpes sores.
Herpes may be transmitted either through sexual contact or non-sexual contact. HSV-1 is much more common than HSV-2.
It is not possible to get herpes from:
The CDC estimates that around 48% of the U.S. population have HSV-1, which causes oral herpes, while around 12% have HSV-2, or genital herpes.
Herpes simplex viruses may be spread by:
- Less commonly, shared objects that touch the sores or saliva of someone with an active outbreak
In some cases, while not as common, herpes simplex can be passed from a pregnant person to their baby during birth.
Both types of herpes simplex can be asymptomatic. A person with no symptoms may still be able to spread the virus via saliva or other body fluids if it is actively shedding.
Viral infections never leave the body.
They may go dormant, during which time a person is not contagious.
Herpes simplex virus does not always reactivate, but is contagious from someone experiencing an outbreak, whether it is their first or one of many.
Most people are contagious a few days before sores appear and until the sores are fully crusted over and no longer producing liquid.
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.
How Is It Spread
The herpes virus is spread by skin-to-skin contact with a person who has the herpes virus:
- Most often, from herpes sores or blisters
- Less often, from normal looking skin where the virusfirst entered the body
- The herpes virus enters the body through the:
- Lining of the mouth
- Regular skin that has small cracks or cuts
People with a weak immune system can get a herpesinfection more easily. A weak immune system is causedby some diseases and by somemedicines used to treat serious diseases.
People who don’t know they have herpes can still spread the virus to others.

Treatment For Genital Herpes
Three drugs are approved to treat genital herpes:
These medications are antiviral drugs called nucleoside analogues. The drugs are used initially to treat a first attack of herpes, and then afterward to either treat recurrent outbreaks or reduce frequency of recurrences .
No drug can cure herpes simplex virus. The infection may recur after treatment has been stopped. Even during therapy, an infected person can still transmit the virus to another person. Drugs can, however, reduce the severity of symptoms, improve healing times, and prevent recurrences.
Antiviral drugs for genital herpes are generally given as pills that are taken by mouth. If people experience very severe disease or complications, they need to be hospitalized and receive an antiviral drug intravenously. Acyclovir is also available as an ointment, which can be used as an adjunct for treatment of initial genital herpes.

Does A Cold Sore On My Mouth Mean I Have Genital Herpes
No, a cold sore on your mouth usually means you have herpes simplex virus type 1 . You can get HSV-1 by kissing someone or sharing utensils, towels, razors, or lipstick with someone who has HSV-1.
HSV-1 cannot turn into HSV-2 , but you can get a cold sore on your mouth from HSV-2 if you give oral sex to someone with HSV-2. Cold sores caused by HSV-1 or HSV-2 are contagious. You can spread it to other people or other parts of your body if you touch an open sore and then touch another part of your body. That means if you have a cold sore and give oral sex to someone, that person will get the herpes virus on his or her genitals.
Avoid touching your cold sore as much as possible. If you touch your cold sore, wash your hands right away to avoid spreading the infection to other parts of your body or other people.
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.

Why Genital Herpes Comes Back
Genital herpes is caused by a virus called herpes simplex. Once you have the virus, it stays in your body.
It will not spread in your body to cause blisters elsewhere. It stays in a nearby nerve and causes blisters in the same area.
If you can, avoid things that trigger your symptoms.
Triggers can include:
- surgery on your genital area
- a weakened immune system for example, from having chemotherapy for cancer
How To Keep Herpes Dormant
One person with genital herpes may work at a high-stress job and be in a stressful relationship, and be more prone to outbreak recurrences. Another may have a more stress-free lifestyle that potentially keeps the virus dormant for years or even decades.
We cant all be stress-free all the time, and thats life. To minimize the frequency of outbreaks, its helpful to manage stress in a healthy way. Getting out for a walk, meditating, practicing yoga or mindfulness, relaxing in a bath, or writing in a diary are examples of ways to cope with and manage stress.
A healthy diet helps physically as well as emotionally, and a lysine-rich diet may suppress the herpes virus. All these factors can contribute to less frequent flare-ups.

How Long After Herpes Outbreak Is It Still Contagious
For oral herpes, cold sores are usually contagious for up to 15 days and are generally no longer contagious once all symptoms have cleared, which includes the blister itself and any scabbing.
Someone carrying genital herpes should wait until 7 days after the sore heals to begin engaging in sexual activity, as the herpes virus can spread from sores not covered by a condom.
Type Of Tests Used To Diagnose Herpes
There are four main types of diagnostic tests that can be used to diagnose herpes. Your doctor will determine which type of test to use based on whether an outbreak is present or not.
If youre experiencing what you believe to be a herpes outbreak, your doctor can use a viral culture test or virus antigen detection test. If youre not experiencing symptoms, you can have an antibody test.
- Viral culture test.This test is used to determine if a sore contains the herpes virus. This test can sometimes produce a false-negative, meaning that it may not detect the virus even though its present.
- Virus antigen detection test. This test is used to determine if antigens to the herpes virus are present in a sore or lesion.
- Antibody test. If youre not experiencing an outbreak yet but still believe you may have been exposed, you can opt to have an antibody test performed. This test will only show a positive result if the antibodies to the virus have been developed. Therefore, this test isnt necessarily recommended for recent exposure.
- Polymerase chain reaction test. With this test, a healthcare provider can screen a sample of your blood or tissue from a sore. They can use this to determine if HSV is present and which type you have.

How Soon Do Symptoms Appear
Symptoms tend to come on suddenly anywhere from two days to two weeks after youve been exposed to the virus.
The appearance of symptoms is called an outbreak. After your initial outbreak is treated, you may have subsequent outbreaks during the next year and occasionally throughout the rest of your life.
Can You Get Herpes From A Toilet Seat
If you experience recurrent genital herpes outbreaks, you may be offered pills with antiviral drugs, including acyclovir, famciclovir, and valacyclovir .
The good news is that there are effective medications for managing herpes. You cant get rid of it, but you can control your symptoms and reduce the likelihood of spreading it to others.

What Are The Symptoms Of Genital Herpes
Most individuals infected with HSV are asymptomatic or have very mild symptoms that go unnoticed or are mistaken for another skin condition. 9 When symptoms do occur, herpes lesions typically appear as one or more vesicles, or small blisters, on or around the genitals, rectum or mouth. The average incubation period for an initial herpes infection is 4 days after exposure. 10 The vesicles break and leave painful ulcers that may take two to four weeks to heal after the initial herpes infection. 5,10 Experiencing these symptoms is referred to as having a first herpes outbreak or episode.
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

How Long Does It Take For Symptoms Of Herpes To Appear
It generally takes anywhere from 4 to 7 days for herpes symptoms to appear. Both genital and oral herpes outbreaks have similar symptoms.
The primary symptom of a herpes outbreak is sores that resemble blisters, called herpes lesions, on the mouth or genitals.
In addition, people may also experience the following symptoms prior to the outbreak:
- pain and redness, especially around the area the outbreak will occur
- itching and tingling, primarily in the outbreak area
- flu-like symptoms, such as fatigue, fever, or swollen lymph nodes
Most of the symptoms that occur before an outbreak indicate that the virus is replicating. Symptoms are usually the worst during the first herpes outbreak.
According to the
Some people with the herpes virus are asymptomatic, which means that they dont experience any physical symptoms of the disease. This doesnt mean that they cant spread the disease, however.
Anyone who has the herpes virus, whether symptomatic or not, can spread the virus to others.
If you have the herpes virus and your body has produced antibodies, it can be detected on a blood test, even if you have no symptoms. The only time the virus might not be detected on a test is if youve been tested too early.
What Are The Symptoms Of Herpes Simplex
Many people with the infection never experience any herpes symptoms. If you do notice symptoms, youll experience them differently depending on whether youre having your first herpes outbreak or a repeat outbreak. Recurring symptoms are usually milder than the first outbreak. Symptoms dont last as long with later outbreaks. Some people may only have one or two outbreaks during their lifetime. Others may have as many as four or five outbreaks a year.
People who do have herpes symptoms may experience:
- Cold sores around their lips, mouth or tongue. They may look crusty or like fluid-filled blisters.
- Tingling, itching or burning.

Reactivation And Recurrent Outbreaks
- Extreme temperatures
- Menstrual periods
