Gonorrhea is one of the most common sexually transmitted infections (STIs) in Canada. It is caused by a bacterium called Neisseria gonorrhoeae and affects the urinary and reproductive tracts. Left untreated, gonorrhea can lead to serious health problems, including infertility. This article explains what gonorrhea is, how it spreads, what symptoms to watch for, and how it is treated in Canada.
What Is Gonorrhea?
Gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae, a Gram-negative bacterium. It is one of the oldest known sexually transmitted infections in recorded medical history. In Canada, it is a Health Canada-reportable infection, meaning healthcare providers must report confirmed cases to public health authorities.
The infection spreads mainly through sexual contact. This includes vaginal, anal, and oral sex. It can also pass from a mother to her newborn during childbirth. However, gonorrhea does not spread through casual contact like hugging, sharing food, or touching doorknobs.
Gonorrhea is very treatable with antibiotics. However, early diagnosis is essential. Without treatment, the infection can cause lasting damage to the reproductive system and other organs.
How Does Gonorrhea Spread?
The most common way gonorrhea spreads is through unprotected sexual contact with an infected person. This includes vaginal, anal, and oral sex. Even when an infected person has no visible symptoms, they can still pass the infection to others.
A pregnant person with gonorrhea can pass the infection to their baby during vaginal delivery. This can cause a serious eye infection in the newborn, known as gonococcal ophthalmia. For this reason, newborn eye drops are routinely offered in many Canadian provinces after birth.
In rare cases, a child may contract gonorrhea through contact with contaminated materials, such as a shared towel used by an infected person. However, sexual transmission remains by far the most common route.
Who Is at Risk?
Anyone who is sexually active can get gonorrhea. However, certain factors increase the risk. These include having multiple sexual partners, not using condoms consistently, and having a history of STIs. Young adults between the ages of 15 and 24 account for a large proportion of gonorrhea cases in Canada.
Furthermore, men who have sex with men (MSM) face a higher risk of gonorrhea, including infections in the throat and rectum. Regular STI testing is especially important for this group. The World Health Organization (WHO) recommends regular testing for all sexually active individuals at higher risk.
Gonorrhea Symptoms in Men and Women
Gonorrhea symptoms vary depending on the person. In some cases, there are no symptoms at all. This makes the infection especially easy to spread without knowing it. Therefore, regular STI testing is one of the best ways to protect yourself and your partners.
Symptoms in Men
In men, the most common sign of gonorrhea is urethritis, which means inflammation of the urethra. Symptoms usually appear between 4 and 20 days after exposure to the infection. The most noticeable sign is a yellowish, thick discharge from the penis that may stain underwear.
Men may also feel a burning or painful sensation when urinating. In addition, the opening of the penis may appear red or swollen. If left untreated, the infection can spread and cause inflammation of the prostate (prostatitis), bladder (cystitis), or epididymis and testicles (epididymo-orchitis).
Without treatment, gonorrhea in men can also lead to narrowing of the urethra over time. This condition, called urethral stricture, makes urination increasingly difficult and may require medical procedures to correct.
Symptoms in Women
In women, gonorrhea symptoms are often mild or even absent. This makes the infection harder to detect and easier to overlook. As a result, many women are diagnosed only after a routine STI test or after a partner is diagnosed.
When symptoms do appear, they may include unusual vaginal discharge, a burning sensation when urinating, and pain in the lower abdomen. Women may also develop cervicitis (inflammation of the cervix) or bartholinitis (inflammation of glands near the vaginal opening).
If the infection spreads to the uterus, fallopian tubes, or ovaries, it can cause pelvic inflammatory disease (PID). PID is a serious complication that may lead to chronic pelvic pain, ectopic pregnancy, and even infertility. Early treatment is the best way to prevent these outcomes.
Symptoms in Newborns
Newborns who contract gonorrhea during delivery may develop gonococcal conjunctivitis, commonly called “pink eye” in newborns. The eyes become red, swollen, and produce a thick discharge. Without prompt treatment, this infection can damage eyesight or even cause blindness.
Canadian hospitals routinely screen pregnant people for gonorrhea. Preventive eye drops or ointment are also offered to newborns in many provinces to reduce this risk.
Symptoms in Children
In rare cases, young children can develop gonorrhea through contact with contaminated materials. In girls, this typically presents as vulvovaginitis, meaning inflammation of the vulva and vagina. Any child suspected of having gonorrhea should be assessed promptly by a healthcare provider.
Atypical and Less Common Presentations
Gonorrhea does not always affect the genitals. In some cases, it can infect the throat after oral sex, causing a sore throat or pharyngitis. It can also affect the rectum after anal sex, causing pain, discharge, or rectal bleeding. These forms of gonorrhea are often overlooked because symptoms may be absent or mistaken for other conditions.
In rare but serious cases, gonorrhea can spread through the bloodstream. This is called disseminated gonococcal infection (DGI). It can cause skin sores, joint pain, fever, and in very rare instances, infection of the heart (endocarditis) or lining of the brain (meningitis). DGI requires urgent medical attention and hospital treatment.
Because gonorrhea can appear in so many different ways, laboratory testing is essential for accurate diagnosis. A doctor cannot diagnose gonorrhea based on symptoms alone.
Diagnosing Gonorrhea in Canada
Diagnosis of gonorrhea is confirmed through laboratory testing. A healthcare provider will collect a swab from the affected area. This could be the urethra, cervix, throat, or rectum, depending on the person’s sexual history and reported symptoms.
The swab is then examined in one of two ways. The first is a direct smear (called a Gram stain), which looks at the bacteria under a microscope. The second is a bacterial culture, which grows the bacteria in a lab to confirm the species. Nucleic acid amplification tests (NAATs) are also widely used across Canada and are highly accurate.
Your family doctor, walk-in clinic, or local sexual health clinic can arrange testing. Many provincial health plans in Canada cover STI testing without direct cost to the patient. You do not need a referral in most cases. You can ask your provincial health authority about testing locations near you.
Gonorrhea Treatment Options
Gonorrhea is treatable with antibiotics. However, treatment must begin as early as possible to prevent complications. The standard treatment in Canada involves an injection of ceftriaxone, often given alongside an oral antibiotic called azithromycin. Your doctor will advise the best approach based on current guidelines.
It is very important to complete the full course of treatment, even if symptoms improve quickly. Stopping antibiotics early can allow the infection to return or become resistant. The Mayo Clinic notes that antibiotic-resistant gonorrhea is a growing concern worldwide. This means some strains of gonorrhea no longer respond to older antibiotics like penicillin.
During treatment, you should avoid all sexual activity until both you and your partner or partners have completed treatment and been confirmed clear of infection. This is critical to prevent reinfection. All recent sexual partners should also be notified and tested, even if they have no symptoms.
Antibiotic Resistance and Gonorrhea
Antibiotic-resistant gonorrhea is a serious and growing public health issue. Over the decades, Neisseria gonorrhoeae has developed resistance to many antibiotics, including penicillin, tetracycline, and fluoroquinolones. Health authorities in Canada and around the world actively monitor resistance patterns to update treatment guidelines.
If your symptoms do not improve after treatment, return to your doctor right away. A different antibiotic or combination of antibiotics may be needed. Follow-up testing is sometimes recommended to confirm the infection has cleared.
Preventing Gonorrhea
The most effective way to prevent gonorrhea is to use condoms correctly every time you have vaginal, anal, or oral sex. Condoms do not offer 100% protection, but they greatly reduce the risk of transmission. Limiting the number of sexual partners also lowers your risk.
Regular STI testing is one of the most important tools for prevention. Many people with gonorrhea have no symptoms. Testing allows early diagnosis and treatment before the infection spreads to others or causes complications. Sexually active Canadians, especially those with new or multiple partners, should speak to their doctor about how often to get tested.
Open communication with sexual partners about STI testing and sexual health is also key. Talking with your partner before sex about testing history can protect both of you. Many Canadian sexual health centres offer confidential testing, counselling, and support without judgment.
When to See a Doctor
You should see a doctor or visit a walk-in clinic if you notice any unusual discharge, burning during urination, pain in the lower abdomen or genitals, or sores near the genitals or rectum. Even if your symptoms are mild or you are unsure, it is always better to get checked.
You should also get tested if a current or recent sexual partner has been diagnosed with gonorrhea or another STI, even if you feel completely fine. Your family doctor, walk-in clinic, or a local sexual health centre can all arrange confidential testing. Most provincial health plans cover STI testing at no out-of-pocket cost.
If you are pregnant, STI screening is part of routine prenatal care in Canada. Ask your midwife or doctor about gonorrhea testing during your pregnancy. Early detection protects both you and your baby. As always, speak with a qualified healthcare provider for personal medical advice suited to your situation.
Frequently Asked Questions About Gonorrhea
Can gonorrhea go away on its own without treatment?
No, gonorrhea does not go away on its own. Without antibiotic treatment, the infection will persist and can spread to other parts of the body. Untreated gonorrhea can cause serious complications such as infertility and pelvic inflammatory disease.
How soon do gonorrhea symptoms appear after infection?
In men, gonorrhea symptoms typically appear between 4 and 20 days after exposure. In women, symptoms may take longer to appear or may never develop at all. Because many people with gonorrhea have no symptoms, regular testing is essential for anyone who is sexually active.
Is gonorrhea curable in Canada?
Yes, gonorrhea is curable with the right antibiotics when diagnosed and treated early. However, antibiotic-resistant strains of gonorrhea are becoming more common, which can make treatment more challenging. Always complete the full course of antibiotics prescribed by your doctor.
Can you get gonorrhea from oral sex?
Yes, gonorrhea can spread through oral sex and infect the throat, causing what is known as pharyngeal gonorrhea. This form of the infection often causes no symptoms or may feel like a regular sore throat. Using a condom or dental dam during oral sex reduces the risk of transmission.
Do I need to tell my partner if I have gonorrhea?
Yes, it is important to notify any recent sexual partners if you are diagnosed with gonorrhea. This allows them to get tested and treated before they develop complications or pass the infection to others. Many sexual health clinics in Canada offer confidential partner notification services to help with this process.
Can gonorrhea affect fertility?
Yes, untreated gonorrhea can lead to infertility in both men and women. In women, the infection can spread to the fallopian tubes and cause pelvic inflammatory disease, which may lead to scarring and blocked tubes. In men, it can cause inflammation of the epididymis, which may affect sperm production and transport.
