About Trichomoniasis STI
Trichomoniasis, also known as "trich," is a sexually transmitted infection (STI) caused by a parasite called Trichomonas vaginalis. It is one of the most common STIs in the United States (US) and affects more women than men. Trichomoniasis is primarily spread through vaginal, oral, or anal sex.
Many people with trichomoniasis do not experience symptoms, but it can cause a foul-smelling discharge and itching in some cases. If left untreated, trichomoniasis can increase the risk of getting other STIs, like HIV. It can also cause complications during pregnancy, such as premature rupture of the membranes and preterm delivery.
It's important to note that even if someone doesn't have symptoms, they can still pass on the infection to their sexual partners. Therefore, it's crucial to seek treatment if you suspect you may have trichomoniasis or if you have been diagnosed with it. The good news is that trichomoniasis is easily treatable with antibiotics
Trichomoniasis is an STI caused by the protozoan parasite Trichomonas vaginalis. This parasite is primarily transmitted through sexual contact, including vaginal, anal, or oral sex. It can be passed between partners even if one partner does not have any symptoms.
Non-modifiable risk factors of trichomoniasis are factors that can’t be changed, including:
- Sex: Trichomoniasis is more common in women than in men. About 2.3 million women between the ages of 14 and 49 acquire trichomoniasis each year.
- Age: Trichomoniasis is more common among older individuals, and one study showed that the most positive cases occurred in the over 50 age group.
Modifiable risk factors of trichomoniasis are factors that can be influenced or changed, includingI:
- Multiple sexual partners: Having multiple sexual partners increases the risk of contracting trichomoniasis. The more partners someone has, the higher their chances of being exposed to the parasite.
- History of other STIs: Individuals who have had other sexually transmitted infections in the past may be at a higher risk of acquiring trichomoniasis.
- Previous trichomoniasis transmission: If someone has had trichomoniasis before, they are at an increased risk of getting re-infected if they engage in sexual activity with an infected partner.
- Unprotected sex: Engaging in sexual activity without using a condom or other barrier method can increase the risk of trichomoniasis transmission.
It's important to note that while these are common risk factors associated with trichomoniasis, anyone who is sexually active can potentially contract the infection. Practicing safe sex by using condoms and getting regular STI screenings can help reduce the risk of trichomoniasis and other STIs.
Many people with trichomoniasis may not experience any symptoms. When symptoms do occur, they may include:
- Itchy, sore, flushed, or burning genitals
- Change in vaginal discharge, such as an increase in volume or change in color to clear, yellow, or green
- Production of thin discharge
- Discomfort during urination (peeing)
These symptoms can occur within 5 to 28 days after coming into contact with the parasite. However, it's important to note that these symptoms are not exclusive to trichomoniasis and can resemble those of other conditions.
As the infection progresses or becomes more severe, additional symptoms may occur. These can include:
- Redness and soreness of the genitals
- Discomfort during sexual intercourse
- Genital itching and burning sensations
It's worth mentioning that most people with trichomoniasis, including those who are pregnant, do not show any symptoms at all. This makes it crucial to get tested if you suspect you may have been exposed to the infection.
To diagnose trichomoniasis, several examinations, tests, and procedures are commonly performed. These include:
- Physical exam: Anyone who suspects they may have acquired trichomoniasis should see a doctor for a physical exam. During this exam, doctors may assess symptoms and examine samples of vaginal fluid, urethral discharge, or urine under a microscope.
- Pelvic exam: A doctor may carry out a pelvic exam to gather more information about the infection and assess its severity.
- Collection of a sample: A healthcare provider will collect a sample of their urine or vaginal secretions to examine under a microscope.
- Microscopic examination: A doctor will use a microscope to look for the presence of the trichomonas parasite in the sample. For women, the sample source is vaginal discharge.
Additional examinations, tests, and procedures may be performed on the sample of vaginal fluid to determine the stage or severity of trichomoniasis include:
- Culture test: In this procedure, cultures are grown from the collected samples. Although it can yield high-quality results, it can take up to 7 days to get the results.
- Nucleic acid amplification test (NAAT): This test has over 90% sensitivity in detecting trichomoniasis. It is a common method used to analyze samples and confirm the presence of the parasite.
It's important to note that pregnant individuals displaying any symptoms of a trichomoniasis infection should seek medical attention right away. Regular OB-GYN appointments usually do not include testing for trichomoniasis, so it's crucial to communicate any concerns or symptoms with your healthcare provider.
Remember, if you receive a positive test result for trichomoniasis, your doctor will prescribe appropriate treatment and discuss next steps with you.
The goals of treatment for trichomoniasis are to kill the parasite, reduce symptoms, and reduce the risk of transmission of the infection.
An antibiotic called metronidazole is the main treatment for trichomoniasis. Key points about metronidazole include:
- Metronidazole can be taken as one large dose or as one tablet twice daily for 7 days.
- It works by killing the trichomonas parasite, which causes the infection.
- This medication is also safe for pregnant individuals.
- Other antibiotics similar to metronidazole may be used, including tinidazole or secnidazole.
Health behavior changes for trichomoniasis treatment include:
- Individuals diagnosed with trichomoniasis should avoid sexual activity until after they have completed their course of antibiotics. This helps prevent transmission of the infection and allows time for the medication to work effectively.
It is important for the sexual partners of individuals diagnosed with Trichomoniasis to receive treatment at the same time. This is known as concurrent treatment or partner therapy. Treating partners helps prevent reinfection and reduces the risk of transmission. The Centers for Disease Control and Prevention (CDC) recommends expedited partner therapy (EPT) as an option for partner treatment. EPT involves providing treatment prescriptions to the patient without clinical assessment of the partners. EPT has been found to be effective in partner treatment for other sexually transmitted infections like chlamydia and gonorrhea.
Retesting for trichomoniasis is recommended approximately 3 months after initial treatment for all sexually active women. This helps identify any potential reinfections that may have occurred.
By following these recommended treatments and strategies, healthcare providers aim to alleviate symptoms, cure the infection, prevent reinfection, and reduce transmission of Trichomoniasis STI. It's important to remember that completing the full course of medication and involving sexual partners in treatment are crucial steps in achieving these treatment goals.
If left untreated, trichomoniasis can cause complications.
Complications commonly associated with trichomoniasis include:
- Pelvic Inflammatory Disease (PID): Trichomoniasis has been found to be associated with PID, which is an infection of the reproductive organs in people with female reproductive systems. PID can lead to long-term complications such as chronic pelvic pain and infertility.
- Pregnancy complications: If someone is pregnant and has untreated trichomoniasis, it can result in preterm labor and low birth weights for the baby. Therefore, it is especially important for pregnant individuals to get tested and treated for trichomoniasis.
- Increased risk of other STIs: Trichomoniasis can increase the risk of acquiring other STIs, such as HIV. This is because the inflammation caused by trichomoniasis makes it easier for viruses like HIV to enter the body.
Treatment for trichomoniasis is crucial to prevent complications and reduce the risk of transmission.
It's important to note that even after treatment, there is a high rate of reinfection among women with trichomoniasis. Therefore, healthcare providers recommend retesting for trichomoniasis approximately three months after initial treatment for all sexually active women.
Remember, if you suspect you have trichomoniasis or any other STI, it's essential to seek medical advice from a healthcare provider. They can provide accurate diagnosis and recommend appropriate treatment options tailored to your specific situation.
