Genital herpes is one of the most common sexually transmitted infections (STIs) in Canada. It is caused by the herpes simplex virus, most often type 2 (HSV-2). This article explains what genital herpes is, how it spreads, what symptoms to expect, and how it is treated. Whether you have just been diagnosed or want to learn more, understanding this condition can help you take care of your health.
What Is Genital Herpes?
Genital herpes is a viral infection spread through sexual contact. The herpes simplex virus type 2 (HSV-2) causes most cases. However, herpes simplex virus type 1 (HSV-1) — the same virus that causes cold sores — can also cause genital herpes through oral sex.
The infection is lifelong. Once the virus enters your body, it stays in your nerve cells. It can become inactive for long periods, then reactivate and cause outbreaks. Many people live with genital herpes and manage it well with the right care and treatment.
According to the World Health Organization (WHO), hundreds of millions of people worldwide live with HSV-2. In Canada, rates of genital herpes have been rising steadily. You are not alone if you have received this diagnosis.
How Does Genital Herpes Spread?
Genital herpes spreads through skin-to-skin sexual contact. This includes vaginal, anal, and oral sex. The virus passes easily, even when no sores or symptoms are visible. This is called asymptomatic shedding, and it makes the infection easy to transmit without knowing it.
You can reduce your risk by using condoms consistently. However, condoms do not fully protect against herpes because the virus can live on skin not covered by a condom. Open communication with sexual partners is an important part of prevention.
The virus does not spread through toilet seats, towels, or casual contact like hugging. It requires direct mucous membrane or skin contact to pass from one person to another.
Who Is at Risk?
Anyone who is sexually active can get genital herpes. However, some factors increase your risk. These include having multiple sexual partners, not using barrier protection, and having another STI, which can make the skin more vulnerable to infection.
People with weakened immune systems — for example, those living with HIV or taking immunosuppressant medications — are at higher risk of more frequent and severe outbreaks. For this group, antiviral treatment is especially important.
Symptoms of Genital Herpes
Not everyone with genital herpes develops noticeable symptoms. In fact, many people do not know they are infected. When symptoms do appear, they can range from mild to quite uncomfortable, especially during the first outbreak.
The First Outbreak
The first episode of genital herpes is usually the most intense. It typically appears within two to twelve days after exposure to the virus. Symptoms often begin with a burning or tingling sensation in the genital area. This is followed by the appearance of small, fluid-filled blisters.
These blisters break open and leave painful sores (ulcers). The pain can be sharp, especially when urine contacts the open sores. In addition, you may experience flu-like symptoms such as fever, body aches, and swollen lymph nodes in the groin area.
The first outbreak usually lasts two to three weeks. It is important to seek medical care during this time, both to confirm the diagnosis and to get appropriate treatment.
Recurring Outbreaks
After the first episode, the virus becomes dormant in your nerve cells. It can reactivate later, causing recurring outbreaks. These repeat episodes are generally shorter and less painful than the first one.
Many people notice warning signs before a recurrence. These signs — called prodromal symptoms — include itching, tingling, or a burning sensation in the affected area. Recognising these early signs can help you start treatment sooner and reduce the duration of an outbreak.
Certain triggers can bring on a recurrence. Common triggers include stress, illness, fatigue, hormonal changes, and sun exposure. Keeping track of your personal triggers can help you manage outbreaks more effectively. For more information on recognising symptoms, visit Mayo Clinic’s genital herpes overview.
Diagnosing Genital Herpes
A healthcare provider diagnoses genital herpes primarily through a physical examination. If sores are present, your doctor may take a swab from one of the blisters or ulcers and send it to a laboratory. The lab grows the virus in a culture to confirm the diagnosis.
Blood tests can detect antibodies to the herpes simplex virus. However, these tests are considered secondary in value. A swab taken directly from an active sore is the most reliable way to confirm genital herpes.
It is worth noting that a diagnosis of genital herpes does not tell you how long you have had the infection. The virus can remain silent for months or years before causing any noticeable symptoms.
Testing in Canada
In Canada, STI testing is covered under most provincial and territorial health plans. You can ask your family doctor for a referral to an STI clinic, or visit a walk-in clinic or sexual health centre in your area. Testing is confidential and non-judgmental. Do not hesitate to ask for testing if you think you may have been exposed.
Treatment Options for Genital Herpes
There is currently no cure for genital herpes. However, antiviral medications can significantly reduce the severity and frequency of outbreaks. They can also lower the risk of passing the virus to a partner.
Antiviral Medications
Acyclovir is the most well-known antiviral medication used to treat genital herpes. Other options include valacyclovir and famciclovir. These medications work by slowing down the reproduction of the virus in your body.
Your doctor may prescribe antivirals in two ways. Episodic treatment means you take medication when an outbreak begins, to shorten its duration. Suppressive therapy means you take a daily dose to reduce the number of outbreaks overall. Your doctor will help you decide which approach suits your situation best.
For people who experience frequent or severe outbreaks — especially those who are immunocompromised — antiviral treatment is particularly beneficial and strongly recommended.
Local Care and Comfort Measures
Beyond antiviral medications, simple local care can help sores heal faster. Gently cleaning the affected area with mild antiseptic solutions helps prevent secondary bacterial infections. Keeping the area dry also promotes healing.
Wearing loose, breathable cotton underwear can reduce discomfort. Over-the-counter pain relievers like acetaminophen or ibuprofen can help manage pain during an outbreak. Always speak with a pharmacist or doctor before starting any new medication.
Genital Herpes and Special Circumstances
Genital Herpes During Pregnancy
Genital herpes requires extra attention during pregnancy. If a mother has an active outbreak at the time of delivery, the virus can pass to the newborn during birth. This is called neonatal herpes, and it can be serious for the baby.
Therefore, if you are pregnant and have genital herpes, it is essential to tell your obstetric care team. Your doctor will monitor you carefully throughout your pregnancy. In some cases, a severe recurrent outbreak near your due date may be a reason to consider a Caesarean section (C-section) to protect the baby during delivery.
Antiviral suppressive therapy in the final weeks of pregnancy can also reduce the risk of an outbreak at the time of birth. Your healthcare provider will guide you on the safest plan for you and your baby.
Genital Herpes and Immunocompromised Individuals
For people with weakened immune systems, genital herpes can cause more frequent, longer, and more severe outbreaks. This group includes people living with HIV, those undergoing chemotherapy, and organ transplant recipients taking immunosuppressant drugs.
In these cases, antiviral treatment is especially important and is often given as long-term suppressive therapy. If you are immunocompromised, speak with your specialist or family doctor about a personalised management plan.

When to See a Doctor
You should see a doctor if you notice any unusual sores, blisters, or burning sensations in your genital area. Do not wait and hope the symptoms go away on their own. Early diagnosis and treatment can make a real difference in how you feel and how you manage the condition going forward.
In Canada, you have several options for care. Your family doctor is a great first point of contact. If you do not have a family doctor, a walk-in clinic or a local sexual health centre can provide confidential testing and treatment. Most provincial health plans cover STI-related care, so cost should not be a barrier to getting help.
You should also see a doctor right away if you are pregnant and think you may have genital herpes, if your symptoms are severe or spreading, or if you have a weakened immune system and experience a new outbreak.
Always consult your doctor or a qualified healthcare provider for a proper diagnosis and personalised treatment plan. The information in this article is for general educational purposes only.
Frequently Asked Questions About Genital Herpes
Can you get genital herpes without having sex?
Genital herpes spreads through direct skin-to-skin sexual contact, including oral, vaginal, and anal sex. It does not spread through toilet seats, towels, or casual everyday contact. However, it can spread through oral sex if one partner has a cold sore caused by HSV-1.
Is genital herpes curable?
There is currently no cure for genital herpes. However, antiviral medications like acyclovir and valacyclovir can effectively manage outbreaks and reduce symptoms. Many people with genital herpes live full, healthy lives with proper treatment and care.
How long does a genital herpes outbreak last?
The first outbreak of genital herpes is usually the most severe and can last two to three weeks. Recurring outbreaks tend to be shorter and milder, often lasting just a few days to a week. Starting antiviral treatment early can shorten the duration of an outbreak.
Can you spread genital herpes when you have no symptoms?
Yes, genital herpes can spread even when no sores or symptoms are present. This is known as asymptomatic viral shedding. Using condoms and taking daily antiviral suppressive therapy can lower, but not completely eliminate, the risk of transmission.
Is genital herpes testing covered in Canada?
In most provinces and territories, STI testing — including testing for genital herpes — is covered under provincial health plans. You can get tested through your family doctor, a walk-in clinic, or a local sexual health centre. Testing is confidential and non-judgmental.
Is it safe to have a baby if you have genital herpes?
Many people with genital herpes have healthy pregnancies and babies. However, it is very important to inform your obstetric care team about your diagnosis. Your doctor may recommend antiviral therapy late in pregnancy and will monitor you closely to protect your baby during delivery.
