Gonorrhea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. Often referred to colloquially as “the clap,” gonorrhea primarily affects the mucous membranes of the reproductive tract, but it can also infect the mouth, throat, eyes, and rectum. While it is one of the most common STIs globally, advances in medicine have made it treatable. However, rising antibiotic resistance has complicated treatment efforts, making awareness, prevention, and timely treatment crucial in combating this public health challenge.
Causes and Transmission
Gonorrhea is caused by the Neisseria gonorrhoeae bacterium, which thrives in warm, moist areas of the body. The bacteria are primarily transmitted through sexual contact, including vaginal, anal, and oral sex. While sexual transmission is the most common route, an infected mother can also pass the infection to her baby during childbirth, leading to complications such as eye infections in newborns.
Importantly, a person does not need to ejaculate to transmit gonorrhea. The bacteria can be spread through contact with the mucous membranes of an infected person. Gonorrhea can also coexist with other STIs, such as chlamydia or syphilis, making dual infections a significant concern.
Anyone who is sexually active can contract gonorrhea, but certain factors increase the risk. These include having multiple sexual partners, inconsistent condom use, having a previous history of STIs, and being under the age of 25. Adolescents and young adults are at the highest risk of infection.
Symptoms of Gonorrhea
Gonorrhea does not always present with obvious symptoms, especially in women, which can delay diagnosis and treatment. When symptoms do occur, they typically manifest within two to 14 days after exposure.
Symptoms in Women:
- Vaginal Discharge: Women with gonorrhea may experience increased vaginal discharge, often yellow or green in color.
- Painful Urination: A burning sensation during urination is a common symptom.
- Abdominal or Pelvic Pain: In some cases, women experience lower abdominal or pelvic pain.
- Bleeding Between Periods: Unexplained vaginal bleeding outside of a regular menstrual cycle can occur.
- Pain During Intercourse: Discomfort or pain during sexual activity may be a sign of an infection.
Untreated gonorrhea in women can lead to serious health complications, such as pelvic inflammatory disease (PID), which can result in chronic pelvic pain, ectopic pregnancy, and infertility.
Symptoms in Men:
- Discharge from the Penis: Men with gonorrhea may notice a white, yellow, or green discharge from the penis.
- Painful Urination: Similar to women, men often experience a burning sensation when urinating.
- Testicular Pain: In some cases, men may feel pain or swelling in one or both testicles.
If left untreated, gonorrhea can lead to epididymitis, a painful condition that affects the tubes attached to the testicles, which can lead to infertility.
Other Possible Symptoms:
- Rectal Infections: Rectal gonorrhea, which can occur after anal sex, may cause symptoms such as discharge, anal itching, soreness, bleeding, and painful bowel movements. However, many rectal infections are asymptomatic.
- Throat Infections: Oral sex can result in gonococcal infections of the throat (pharyngeal gonorrhea), which usually cause mild symptoms or none at all. If symptoms are present, they may include a sore throat or swollen lymph nodes.
- Eye Infections: If the eyes are exposed to infected bodily fluids, gonorrhea can cause conjunctivitis (pink eye), leading to redness, swelling, and discharge.
Complications of Untreated Gonorrhea
One of the most concerning aspects of gonorrhea is its potential to cause severe health problems if left untreated. Some of the long-term complications include:
- Pelvic Inflammatory Disease (PID): Women are at risk of developing PID, which can cause chronic pain, infertility, and an increased risk of ectopic pregnancy.
- Infertility: Both men and women can become infertile due to gonorrhea. In men, the infection can scar the reproductive tract, particularly the epididymis, while in women, damage to the fallopian tubes can prevent fertilization.
- Disseminated Gonococcal Infection (DGI): When gonorrhea spreads to the bloodstream, it can cause DGI, a serious condition characterized by fever, joint pain, skin sores, and swelling. DGI can be life-threatening if not treated promptly.
- Increased HIV Risk: Gonorrhea infection increases the risk of contracting and transmitting HIV, the virus that causes AIDS.
Diagnosis
The diagnosis of gonorrhea typically involves laboratory tests. A healthcare provider may collect samples from potentially infected areas, such as the throat, urethra, vagina, or rectum. The most common diagnostic tests include:
- Nucleic Acid Amplification Test (NAAT): This is the preferred method for detecting gonorrhea. NAATs detect the genetic material of the bacteria and are highly accurate.
- Gram Stain: This test involves staining a sample of discharge and examining it under a microscope to identify the bacteria. It is more commonly used for diagnosing gonorrhea in men.
- Culture Test: A bacterial culture can be grown from a sample to confirm the infection and determine antibiotic susceptibility.
Treatment
Gonorrhea is treatable with antibiotics, but recent years have seen an increase in strains resistant to multiple drugs, complicating treatment. The Centers for Disease Control and Prevention (CDC) currently recommends dual therapy, typically involving a single dose of the injectable antibiotic ceftriaxone, along with an oral dose of azithromycin.
The increasing prevalence of antibiotic-resistant strains of Neisseria gonorrhoeae poses a significant public health threat. Some strains have become resistant to nearly all classes of antibiotics used to treat gonorrhea. This has led to urgent calls for new treatments and vigilant monitoring of antibiotic effectiveness.
It is essential for sexual partners of infected individuals to be tested and treated to prevent reinfection. Additionally, those diagnosed with gonorrhea should avoid sexual activity until they and their partners have completed treatment and are free from infection.
Prevention
Preventing gonorrhea involves practicing safe sexual behaviors. Key preventive measures include:
- Consistent and Correct Condom Use: Using condoms during vaginal, anal, and oral sex significantly reduces the risk of gonorrhea transmission.
- Regular STI Screenings: Those who are sexually active, particularly with multiple partners, should undergo regular screenings for STIs, including gonorrhea.
- Limiting Sexual Partners: Reducing the number of sexual partners can lower the risk of contracting gonorrhea.
- Open Communication: Partners should have open discussions about STI status and history before engaging in sexual activity.
- Abstinence: The surest way to prevent gonorrhea and other STIs is to abstain from sexual activity.
Final Thoughts
Gonorrhea remains a common and potentially dangerous sexually transmitted infection. While it is treatable, increasing antibiotic resistance underscores the importance of prevention, timely diagnosis, and effective treatment. Safe sexual practices, routine testing, and public health efforts to address antibiotic resistance are essential in controlling the spread of gonorrhea and protecting individual and public health.
