STDs that cause itching: Diagnosis and Treatments
Common STDs That Cause Itching and Their Diagnosis
Sexually transmitted diseases (STDs) and sexually transmitted infections (STIs) can be passed from person to person during sexual contact and are caused by viruses, bacteria, and parasites. Itching is a common symptom of STIs, which can often be cured before they develop into diseases, but it can also indicate an STD. Here are the five most common STDs that cause itching, along with their symptoms and diagnosis methods:
1. Chlamydia
Chlamydia is a bacterial STD that often causes itching in the genital area, accompanied by a burning sensation during urination and a watery, yellow discharge from the penis or vagina. It can also cause inflammation and discomfort in the rectum, especially after anal sex.
Diagnosis and Treatment:
- Chlamydia is commonly diagnosed with a urine test.
- Treatment involves antibiotics, which usually clear the infection within 1-2 weeks.
- Sexual contact should be avoided during treatment, and it’s possible to get re-infected even after successful treatment.
2. Gonorrhea
Gonorrhea, caused by the bacterium Neisseria gonorrhoeae, can lead to itching in the genital area, along with a greenish-yellow, pus-like discharge. Pain or burning during urination may also occur.
Diagnosis and Treatment:
- Gonorrhea is diagnosed with urine samples and swabs from the affected area.
- Treatment involves antibiotics, often administered as an injection.
- Sexual activity should be avoided for 6-7 days after treatment, and both partners should be tested and treated to prevent reinfection.
3. Trichomoniasis
Trichomoniasis is a parasitic STD that causes significant itching in the vagina or penis, along with a frothy, yellow-green discharge and a strong, unpleasant odor.
Diagnosis and Treatment:
- Diagnosis involves testing vaginal fluid in females and a swab from the penis in males.
- Treatment includes a single large dose of antibiotics like tinidazole, secnidazole, or metronidazole, or multiple doses over 6-7 days.
- Avoid alcohol and sexual contact during treatment.
4. Herpes
Herpes, caused by the herpes simplex virus (HSV), results in painful, itchy blisters or sores in the genital area and sometimes on the mouth or lips. The initial outbreak is usually the most severe.
Diagnosis and Treatment:
- Diagnosis involves blood tests and samples from active sores to identify HSV-1 or HSV-2.
- There is no cure, but long-term antiviral medications can reduce outbreaks and prevent transmission to sexual partners.
5. Pubic Lice (Crabs)
Pubic lice, or "crabs," are small insects that infest the pubic area and cause intense itching. They can be seen as tiny, crab-like creatures on the skin or in the pubic hair.
Diagnosis and Treatment:
- Diagnosis is confirmed by visual examination.
- Treatment involves special shampoos or lotions with 1% pyrethrin, stronger lotions like malathion, or pills like ivermectin.
Takeaway
Itching can be a symptom of STDs that require prompt treatment to prevent spreading. Avoid sexual contact during treatment, and remember that being treated for an STD does not provide immunity from future infections. Contact your local sexual health clinic for diagnosis and treatment to avoid long-term complications.
