1. Human Immunodeficiency Virus (HIV)
HIV is a life-threatening viral infection that weakens the immune system. It’s transmitted through sexual contact, sharing needles, or from mother to child during childbirth.
Symptoms
Early HIV signs can appear 2-4 weeks after exposure and are often called acute HIV infection. Symptoms like fever, fatigue, swollen lymph nodes, night sweats, sore throat, and headaches mimic the flu. Muscle aches, joint pain, and rash may also occur. These symptoms usually last a few weeks and may resolve independently, often leading to mistaken recovery.
After this phase, many remain asymptomatic for years while the virus silently damages the immune system. This “clinical latency” period means individuals can still spread the virus without knowing, making regular testing vital for sexually active people, even without symptoms.
Testing & Treatment:
HIV can be detected through a rapid HIV test, which provides results in as little as 20 minutes, or through standard blood tests that are more comprehensive. It’s important to test regularly, especially after any potential exposure. With early detection, antiretroviral therapy (ART) can help maintain a low viral load, significantly reducing the risk of transmitting the virus to others and delaying or preventing the progression of AIDS.
2. Herpes Simplex Virus (HSV)
Herpes Simplex Virus (HSV) causes herpes infections, categorized into HSV-1 and HSV-2. HSV-1 primarily causes oral herpes, characterized by cold sores or fever blisters around the mouth. HSV-2 is typically associated with genital herpes, leading to sores in the genital or anal area. The virus is highly contagious and can be spread through direct contact with infected skin, mucous membranes, or bodily fluids.
Symptom
Herpes infections can present as painful blisters or sores in the oral or genital areas. Initial outbreaks can be severe, with symptoms including itching, burning, and pain in the affected area. Recurrent outbreaks are common and may be triggered by stress, illness, or hormonal changes. Many individuals with HSV are asymptomatic and may not be aware they are infected.
Testing & Treatment
Herpes can be diagnosed through a blood test that detects antibodies to the virus or through a swab of an active sore. While there is no cure for herpes, antiviral medications can help manage symptoms, reduce the frequency of outbreaks, and lower the risk of transmission. Our lab offers comprehensive HSV testing to assist in diagnosis and guide effective treatment options.
3. Gonorrhea
Gonorrhea is a common bacterial infection caused by Neisseria gonorrhoeae. It can infect the genitals, throat, and rectum. Gonorrhea is transmitted through sexual contact with an infected person and can affect both men and women. If left untreated, it can lead to serious health complications, including infertility and an increased risk of HIV.
Symptoms
Symptoms of gonorrhea may vary depending on the site of infection. In the genitals, symptoms can include painful urination, abnormal discharge, and in women, pelvic pain or abnormal bleeding. Gonorrhea can also cause sore throat or rectal pain and discharge if contracted in those areas. Many individuals may not experience any symptoms, making regular testing crucial.
Testing & Treatment
Gonorrhea can be detected through a urine sample or a swab from the affected area. Prompt treatment is essential to prevent complications. Gonorrhea is effectively treated with antibiotics, though some strains are becoming resistant to treatment. Our lab offers gonorrhea testing as part of basic and comprehensive STD panels to ensure accurate diagnosis and effective treatment.
4. Hepatitis C
Hepatitis C is a viral infection caused by the Hepatitis C virus (HCV) that primarily affects the liver. It is commonly transmitted through blood-to-blood contact, such as sharing needles, receiving contaminated blood products, or through sexual contact. Chronic Hepatitis C can lead to serious liver conditions, including cirrhosis and liver cancer.
Symptoms
Many individuals with Hepatitis C may not experience symptoms, especially in the early stages. When symptoms do occur, they can include jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, dark urine, and unexplained weight loss. Acute Hepatitis C may present with flu-like symptoms, but chronic infection often remains asymptomatic until significant liver damage occurs.
Testing & Treatment
Hepatitis C is diagnosed through blood tests that detect HCV antibodies and measure the viral load. Early detection is important for effective treatment. Modern antiviral medications can cure Hepatitis C in most cases, significantly reducing the risk of liver damage. Our lab provides comprehensive Hepatitis C testing to assist in early diagnosis and guide treatment options.
5. Hepatitis B
Hepatitis B is a viral infection that attacks the liver and can lead to serious liver conditions such as cirrhosis or liver cancer. It is transmitted through contact with infectious body fluids, including blood, semen, and vaginal fluids. Hepatitis B is often spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth.
Symptoms
Symptoms of Hepatitis B can range from mild to severe and may include dark urine, jaundice (yellowing of the skin and eyes), fatigue, abdominal pain, and nausea. However, many individuals with Hepatitis B are asymptomatic, particularly in the early stages, which makes regular testing important.
Testing & Treatment
Detection of Hepatitis B is done through blood tests that identify the presence of the virus or the body’s immune response to it. Although there is no cure for chronic Hepatitis B, antiviral medications can help manage the infection and reduce the risk of liver damage. Our lab includes Hepatitis B testing in its full STD panel, providing accurate results and facilitating timely intervention.
6. Syphilis
Syphilis is a sexually transmitted bacterial infection that progresses through distinct stages if left untreated. It starts with a painless sore, a chancre, and can advance to more severe symptoms affecting various organs and systems. Syphilis can be transmitted through direct contact with these sores during sexual activity.
Symptoms
The initial sign of syphilis is a painless sore or ulcer at the site of infection, typically on the genitals, anus, or mouth. This is followed by a rash that can appear on the trunk or extremities. In the late stages, syphilis can cause severe health problems, including damage to internal organs, cardiovascular issues, and neurological complications.
Testing & Treatment
Syphilis can be detected at any stage through a blood test that looks for antibodies produced in response to the infection. Early treatment with antibiotics, usually penicillin, is highly effective. Our lab provides syphilis testing as part of our STD panels to ensure prompt diagnosis and treatment.
7. Chlamydia and Gonorrhea
Chlamydia and gonorrhea are common bacterial STDs that often occur together. Both infections can affect the reproductive organs and lead to serious health complications if not treated. They are spread through unprotected sexual contact and can be transmitted through vaginal, anal, or oral sex.
Symptoms
Symptoms of chlamydia and gonorrhea can include abnormal discharge from the genitals, painful urination, and pelvic pain. However, many individuals with these infections may not exhibit symptoms, which increases the risk of spreading the infection and developing complications.
Testing & Treatment
Testing for chlamydia and gonorrhea is commonly done using a urine sample or swab. Both infections are treatable with antibiotics. Our lab offers testing for chlamydia and gonorrhea as part of a comprehensive STD panel, ensuring effective diagnosis and treatment.
8. Trichomoniasis
Trichomoniasis is a parasitic infection caused by the protozoan Trichomonas vaginalis. It affects both men and women but is more commonly reported in women. The infection is spread through sexual contact and can cause significant discomfort if left untreated.
Symptoms
In women, symptoms include itching, burning during urination, and abnormal discharge that may be frothy or greenish. Men may experience irritation inside the penis, discharge, or discomfort during urination. Like other STDs, Trichomoniasis can be asymptomatic, making regular screening important for sexually active individuals.
Testing & Treatment
Trichomoniasis is diagnosed through a lab test that examines a sample of vaginal fluid or a urine sample. Treatment typically involves a course of antibiotics, such as metronidazole or tinidazole. Our lab provides Trichomoniasis testing as part of our STD panels to facilitate accurate diagnosis and effective treatment.
9. Mycoplasma genitalium
Mycoplasma genitalium is a bacterial infection that can affect the urinary and genital tracts. It is a less common but increasingly recognized cause of urethritis in men and cervicitis in women. The bacterium is transmitted through sexual contact and can be challenging to diagnose due to its subtle symptoms and lack of widespread testing.
Symptoms
Common symptoms of Mycoplasma genitalium include painful urination, abnormal discharge, and discomfort in the genital area. However, many individuals may be asymptomatic, which can lead to delayed diagnosis and increased risk of transmission. Some people may also experience pelvic pain or bleeding between periods.
Testing & Treatment
Diagnosis of Mycoplasma genitalium requires a specialized test that detects the presence of the bacteria. Treatment typically involves antibiotics, such as azithromycin or doxycycline. Due to the specialized nature of testing and treatment, consulting with a healthcare provider is important. Our lab offers testing for Mycoplasma genitalium to help ensure accurate diagnosis and effective treatment.
10. Pubic Lice (Crabs)
Pubic lice, also known as crabs, are small parasitic insects that infest the hair in the genital area. Although they are not classified as a disease, they are considered a sexually transmitted infection due to their method of transmission through close physical contact. Pubic lice can also be spread through infested clothing, bedding, or towels.
Symptoms
The primary symptom of pubic lice infestation is intense itching in the genital area caused by an allergic reaction to the bites. Visible signs include lice or their eggs (nits) attached to the hair shafts. In severe cases, scratching can lead to secondary bacterial infections.
Testing & Treatment
Treatment for pubic lice involves over-the-counter lotions or shampoos to kill lice and their eggs. These treatments are usually effective when used according to the instructions. Washing all infested clothing, bedding, and towels in hot water is also important to prevent re-infestation.
