Genital herpes is one of the most common sexually transmitted infections (STIs) in Canada. It spreads easily through sexual contact and can affect anyone who is sexually active. This article explains what causes genital herpes, what symptoms to watch for, and what treatment options are available to you through your family doctor or local walk-in clinic.
What Is Genital Herpes?
Genital herpes is a highly contagious viral infection. It spreads mainly through vaginal, oral, or anal sex with an infected person. However, you can catch it even when your partner shows no visible sores or symptoms.
In rare cases, a pregnant person with an active infection can pass the virus to their newborn during childbirth. This is known as neonatal herpes, and it can be serious. If you are pregnant and have a history of herpes, it is important to speak with your doctor early in your pregnancy.
According to the World Health Organization (WHO), more than 3.7 billion people under the age of 50 carry the herpes simplex virus type 1. An estimated 417 million people between the ages of 15 and 49 are infected with herpes simplex virus type 2 worldwide.
Causes of Genital Herpes
Genital herpes is caused by the herpes simplex virus (HSV). There are two types: HSV-1 and HSV-2.
HSV-1 vs. HSV-2
HSV-2 is the most common cause of genital herpes. It spreads through sexual contact. HSV-1, which typically causes cold sores around the mouth, can also cause genital herpes through oral sex.
Both types of the virus are very contagious. Furthermore, both are lifelong infections with no cure. Once the virus enters your body, it stays there permanently — though it may remain inactive for long periods.
How Genital Herpes Spreads
HSV-1 most often spreads through contact with infected saliva. HSV-2 spreads through sexual contact or from a birthing parent to a newborn. Importantly, the virus can spread even when there are no visible sores. This is called asymptomatic shedding, and it makes genital herpes especially easy to transmit unknowingly.
How Common Is Genital Herpes in Canada?
Genital herpes is one of the most widespread STIs in Canada and around the world. Reported cases have increased by roughly 30% since the 1970s. Young people and adolescents are particularly affected.
Genital herpes occurs more often in women than in men. This is partly due to biological differences in how the virus is transmitted. Of the 100 known herpesviruses that infect animals, only 8 infect humans.

Symptoms of Genital Herpes
Many people with genital herpes have no symptoms at all. Others experience mild symptoms that they may mistake for something else, like a skin irritation or ingrown hair. As a result, many people do not know they are infected.
First Outbreak Symptoms
The first outbreak of genital herpes is usually the most severe. Symptoms typically appear 2 to 7 days after exposure to the virus. The first outbreak can last several weeks.
Common symptoms during a first outbreak include:
Redness, warmth, or itching around the genitals
Small blisters (1–2 mm) that appear on or around the genitals
Blisters that burst, crust over, and heal
Swollen, tender lymph nodes in the groin
Fever and headache
Muscle aches and general tiredness
Painful urination (burning when you pee)
Vaginal or urethral discharge
The skin sores follow a clear pattern. First, the skin around the genitals becomes inflamed. Then small blisters appear. After that, the blisters break open, crust over, and gradually heal.
Recurring Outbreaks
After the first outbreak, the virus travels to the nervous system and becomes inactive. However, it can reactivate at any time. Recurring outbreaks are usually shorter and less painful than the first one.
On average, people with genital herpes experience about four outbreaks per year. However, this varies widely from person to person. Over time, outbreaks tend to become less frequent.
What Triggers a Flare-Up?
Several factors can reactivate the virus. Common triggers include:
Stress
Illness or fever
Surgery or physical trauma
Vigorous sexual activity
Changes in diet
Menstruation
Triggers differ from person to person. Keeping a simple journal of outbreaks may help you identify your personal triggers over time.
How Is Genital Herpes Diagnosed?
Your doctor can often diagnose genital herpes by visually examining the affected area during an active outbreak. If the sores look typical, no further testing may be needed right away. However, if the sores look unusual, your doctor may take a swab sample from a blister for lab testing.
Blood Tests and Other Methods
Diagnosing genital herpes between outbreaks is more difficult, since there are no visible sores. In those cases, a blood test to detect HSV-1 or HSV-2 antibodies can help. However, blood tests are not always accurate, so your doctor will interpret results carefully alongside your symptoms and history.
For women, a doctor may also examine the cervix for internal sores. For men, the urethra may be checked. Fluid from blisters, throat swabs, and stool samples can also be tested in some situations.
If you are not sure where to get tested, your family doctor, a walk-in clinic, or a sexual health centre in your province can arrange the right tests for you. Most provincial health plans in Canada cover STI testing when medically necessary.
Treatment for Genital Herpes
There is currently no cure for genital herpes. However, treatment can make outbreaks shorter, less painful, and less frequent. Your doctor can recommend the best approach based on your situation.
Antiviral Medications
Antiviral medications are the main treatment for genital herpes. They do not eliminate the virus, but they do help control it. Common antivirals include acyclovir, valacyclovir, and famciclovir. These are available in oral (pill) form or as topical creams.
For frequent outbreaks, your doctor may recommend suppressive therapy. This means taking antiviral medication daily over a long period. Suppressive therapy can reduce the number of outbreaks and lower the risk of passing the virus to a partner.
Managing Discomfort at Home
Over-the-counter pain relievers, such as acetaminophen or ibuprofen, can ease discomfort during an outbreak. Keeping the affected area clean and dry also helps with healing. Loose-fitting, breathable underwear can reduce irritation.

When to See a Doctor
You should speak with your family doctor or visit a walk-in clinic if you notice any unusual sores, blisters, or discharge in the genital area. You should also get checked if a sexual partner tells you they have been diagnosed with genital herpes.
If you are pregnant and have a history of herpes, bring it up at your first prenatal visit. Your doctor can take steps to protect your baby during delivery. Do not wait until late in your pregnancy to raise the topic.
Even if you have no symptoms, regular sexual health check-ups are a good habit. Most provincial health plans across Canada cover these visits. Your family doctor, walk-in clinic, or local sexual health centre can help you access confidential testing and care.

Frequently Asked Questions About Genital Herpes
Can you get genital herpes without having sex?
Genital herpes spreads primarily through sexual contact, including vaginal, oral, and anal sex. However, it can also spread through skin-to-skin contact with an infected area, even without penetration. Using condoms and dental dams reduces the risk, but does not eliminate it completely.
Can genital herpes go away on its own?
Individual outbreaks of genital herpes do heal on their own, usually within two to four weeks. However, the virus itself stays in your body permanently and can reactivate. Antiviral medications can help reduce how often and how severely outbreaks occur.
Is genital herpes covered by provincial health plans in Canada?
Testing and medical consultations for genital herpes are generally covered under provincial health plans when medically necessary. Coverage for antiviral medications varies by province and by drug benefit plan. Your family doctor or pharmacist can help you understand what is covered in your province.
Can I have genital herpes and not know it?
Yes. Most people with genital herpes have no obvious symptoms or only very mild ones. As a result, many people are unaware they carry the virus. A blood test can detect HSV antibodies even when there are no active sores.
Can genital herpes affect my baby during pregnancy?
Yes. A birthing parent with an active genital herpes outbreak can pass the virus to the baby during vaginal delivery. This is called neonatal herpes and can be serious. If you have a history of genital herpes, tell your doctor early in your pregnancy so they can plan the safest delivery approach.
How can I reduce the risk of spreading genital herpes to my partner?
Using condoms consistently during sex significantly lowers the risk of spreading genital herpes. Daily antiviral medication (suppressive therapy) can also reduce transmission risk. Being open with your partner about your status and avoiding sexual contact during active outbreaks are also important steps.
