Are Canker Sores Caused By The Herpes Virus
Canker sores are not caused by the herpes virus or by any other virus. In fact, the cause of canker sores is unknown, although they may be triggered by a minor injury in your mouth from dental work or brushing too hard, an allergy, a vitamin B deficiency, stress, or a food intolerance. Some medical conditions, such as celiac disease and inflammatory bowel disease, may also cause canker sores, and they often occur in families, so it’s possible genetics or environment play a part, too.
Canker sores typically appear as small, round, or oval whitish sores with a red border, according to the Mayo Clinic. They typically occur on the tongue, inside the cheeks, inside the lips, or on the gums. The medical term for a canker sore is aphthous ulcer. Canker sores can be quite painful, but they usually heal within about two weeks without leaving any scarring.
Unlike cold sores, which usually occur outside the mouth, canker sores occur only inside the mouth. Like cold sores, canker sores are recurrent, but they are not contagious: You cant give a canker sore to another person. Canker sores occur more often in teenagers and young adults, and they are more common in women than men.
Why Its Important To Tell Your Partner
Herpes viruses are extremely contagious. And its not just the risk of spreading a cold sore that you should be worried about.
This is because herpes can spread from the mouth to the genitals or from the genitals to the mouth. Skin-to-skin contact is all that is needed.
Having an open sore also increases your risk of an STI by providing the virus or bacteria a direct route into the body. Herpes can actually promote HIV infection by attracting the immune cells the HIV virus targets and infects.
To this end, it is just as important to discuss both of your sexual histories and not just herpes. As awkward as this may seem, it allows you both to explore whether its time to get STI testing from your healthcare provider or local health clinic.

How Do I Know If I Have Genital Herpes
Most people with genital herpes have no symptoms or have very mild symptoms. Mild symptoms may go unnoticed or be mistaken for other skin conditions like a pimple or ingrown hair. Because of this, most people do not know they have a herpes infection.
Herpes sores usually appear as one or more blisters on or around the genitals, rectum or mouth. This is known as having an outbreak. The blisters break and leave painful sores that may take a week or more to heal. Flu-like symptoms also may occur during the first outbreak.
People who experience an initial outbreak of herpes can have repeated outbreaks, especially if they have HSV-2. However, repeat outbreaks are usually shorter and less severe than the first outbreak. Although genital herpes is a lifelong infection, the number of outbreaks may decrease over time.
Ask a healthcare provider to examine you if:
- You notice any symptoms or
- Your partner has an STD or symptoms of an STD.
STD symptoms can include an unusual sore, a smelly genital discharge, burning when peeing, or bleeding between periods .
Complications Of Cold Sores
Cold sores are usually mild, but may cause complications in rare cases. People with weak immune systems caused by illness or treatments such as chemotherapy are particularly at risk of complications.
Dehydration sometimes occurs if drinking fluids becomes painful. Young children are particularly at risk of becoming dehydrated.
The herpes simplex virus can also spread to other parts of your body. Examples of when this can occur include:
- skin infections these often occur if the virus comes into contact with broken skin, such as a cut or graze, or a skin condition such as eczema
- herpetic whitlow this causes painful sores and blisters to appear on and around your fingers
- herpetic keratoconjunctivitis this causes swelling and irritation of your eye area and sores to develop on your eyelids
Left untreated, herpetic keratoconjunctivitis can cause the cornea, the transparent layer at the front of your eye, to become infected, which can eventually lead to blindness.
It’s therefore important not to touch your eyes if you have an unhealed cold sore. If you must touch your eyes for example, to remove contact lenses wash your hands thoroughly first.
In very rare cases, encephalitis, a condition where the brain becomes inflamed and swollen, can be caused by the cold sore virus spreading to the brain. It can be treated with intravenous injections of antiviral medications, such as aciclovir.

What About Chlamydia The Most Common Std
Chlamydia is caused by bacteria, whereas herpes is caused by a virus. This is why chlamydia is easily treated and cured with antibiotics. However, many people have chlamydia and dont know it because they don’t have any symptoms. That’s why people who are at higher risk of chlamydia, including sexually active young women and men who have sex with other men, are advised to get a test for chlamydia every year.
If you don’t treat chlamydia, it can increase the chances of both men and women getting or giving HIV and AIDS, according to Medline Plus. Untreated chlamydia can also cause serious pelvic inflammatory disease in women, which can lead to infertility, and in men it can spread to the testicles and the tube that carries sperm, causing inflammation.
Screening for chlamydia is usually done by taking a urine sample or a swab from your genitals. Results of these tests are usually found quickly. Different testing methods are used for infections of the rectum and throat, and these take more time.
While the only way to completely avoid getting chlamydia or herpes is to not have sex, you can reduce your chances of getting both by being in a long-term, mutually monogamous relationship with a partner who is not infected with an STD and by using latex condoms every time you have sex.
How Do Doctors Diagnose Oral Herpes
A doctor will base a presumptive diagnosis on information provided by the patient and on the physical examination. The characteristic appearance of the herpes sores leaves little doubt about the diagnosis, so the typical appearance of the sores is key to the diagnosis. This appearance helps distinguish oral herpes from oral thrush, shingles, gonorrhea, and syphilis. In addition, chapped or sunburned lips can resemble oral herpes, but the tissue stain shows no virus-induced cell changes. Further testing is usually not necessary but is sometimes done.
If a definitive diagnosis is needed, because, for example, the infection involves other organ systems, the doctor may conduct laboratory tests listed below:
- A sample from the sores to identify the virus as HSV
- A viral culture analysis
- A staining test called the Tzanck smear
- Antigen and antibody studies

Herpes Myths To Stop Freaking Out About
A surprising number of people you know probably have herpes.
Shocked? You shouldnt be, since the virus is very common. According to the World Health Organization, 3.7 billion people under age 50 have herpes simplex virus type 1 thats 67 percent of the global population in that age bracket. Another 417 million people between ages 15 and 49 worldwide have herpes simplex virus type 2 .
Many people consider HSV-1 more benign, but it turns out theres not much difference between the two types of virus. While its true that HSV-2 is a sexually transmitted disease and can cause genital sores or blisters, type 1 can do the same thing.
One big misconception is that cold sores are caused by HSV-1 and genital herpes are always type 2, but thats not always the case, says Sarah Vensel, a physician assistant in San Francisco. Cold sores are so common theyve been normalized at this point. But genital herpes is sometimes the exact same virus just in a different location.
Not only is herpes incredibly common its also totally manageable. Allow us to set your mind at ease and debunk three widespread herpes myths:
How To Check If You Have Asymptomatic Herpes
If you have no herpes symptoms but believe you might have been exposed to the virus, you can take a herpes test to verify whether or not youre infected.
The most accurate herpes testing method for asymptomatic people is an IgG test, which checks for the presence of IgG antibodies in your blood. These antibodies can signal a herpes infection using certain testing methods, they can also be used to differentiate between HSV-1 and HSV-2.
IgG antibodies can take several months to form after a herpes infection, meaning youll typically need to wait for 12 to 16 weeks before taking an IgG test to make sure you receive an accurate result.
If youre concerned that you might have asymptomatic herpes, the best approach is to speak to your doctor about testing options. Your doctor will be able to schedule a test based on the date of your potential exposure to the virus and provide you with an accurate diagnosis. If you discover you do have HSV-1 or HSV-2, the most important thing is to not panic. These viruses are extremely common, and there are a variety of anti-viral medications out there to help minimize the severity and requency of outbreaks. Most notably, vacyclovir.

While genital ulceration is often associated with herpes, it can be the result of several other conditions, including but not limited to, other sexually transmitted diseases, inflammatory conditions, skin irritation, and allergic skin lesions. In addition to herpes, the main sexually transmitted diseases that present with a genital ulcer are primary syphilis and chancroid. In the United States, syphilis infection is more common than chancroid.
What Happens If I Dont Receive Treatment
Genital herpes can cause painful genital sores and can be severe in people with suppressed immune systems.
If you touch your sores or fluids from the sores, you may transfer herpes to another body part like your eyes. Do not touch the sores or fluids to avoid spreading herpes to another part of your body. If you do touch the sores or fluids, quickly wash your hands thoroughly to help avoid spreading the infection.

The skin on your genitals, mouth, and eyes can be infected easily. Other areas of skin may get infected if theres a way for the herpes virus to get in, like through a cut, burn, rash, or other sores. You dont have to have sex to get herpes. Sometimes herpes can be passed in non-sexual ways, like if a parent with a cold sore gives you a peck on the lips. Most people with oral herpes got it when they were kids. A mother can pass genital herpes to a baby during vaginal childbirth, but thats pretty rare.
You can spread herpes to other parts of your body if you touch a herpes sore and then touch your mouth, genitals, or eyes without washing your hands first. You can also pass herpes to someone else this way.
Herpes is most contagious when sores are open and wet, because fluid from herpes blisters easily spreads the virus. But herpes can also shed and get passed to others when there are no sores and your skin looks totally normal.
Most people get herpes from someone who doesnt have any sores. It may live in your body for years without causing any symptoms, so its really hard to know for sure when and how you got it. Thats why so many people have herpes its a pretty sneaky infection.
Because the virus dies quickly outside the body, you cant get herpes from hugging, holding hands, coughing, sneezing, or sitting on toilet seats.

There are two instances in which herpes poses a more severe risk, but neither of these instances involves oral herpes. For example:
- Neonatal herpes is a risk for infants born to mothers with genital herpes. It can lead to neurological disability and is potentially fatal.
- Herpes simplex encephalitis occurs when herpes infects a persons central nervous system . Its treatable, but can be fatal if not treated properly.
