Trichomoniasis

What is Trichomoniasis?

Trichomoniasis, also referred to as "trich", is a sexually transmitted infection. It is caused by a parasite called Trichomonas vaginalis, which affects the urogenital tract. It spreads from person to person through sexual contact, most commonly when sex occurs without a condom with someone who carries the parasite.

One of the most challenging aspects of trichomoniasis is that most people with it have no symptoms. These patients can unknowingly pass the infection to others. This is a significant reason why the infection is widely underdiagnosed and continues to spread.

How Common is Trichomoniasis in India?

Comprehensive national data on trichomoniasis in India remains limited. As per the available data, the prevalence of trichomoniasis among women ranges widely from 0.4% to as high as 27.4%. In men, the prevalence ranges from 0% to 5.6%. Among women attending STI clinics specifically, infection rates have been found to be even higher, ranging from 8.5% to 34%, pointing to a significant burden among those already at risk.

Regional data underlines just how serious the situation can be in some places. A study in Gujarat found a prevalence of almost 34% among women seeking reproductive health services. This is evident in remote regions like the Andaman and Nicobar Islands, where the prevalence was high among married women, but very few women sought treatment, and only 0.9% of the cases were reported formally. These numbers together point to a critical need for better screening, awareness, and access to treatment across the country.

What are the Symptoms of Trichomoniasis?

Up to 70% of people with trichomoniasis never develop any noticeable symptoms. When symptoms do appear, they typically emerge between 5 and 28 days after exposure, though in some cases they may take longer. Here are the common signs of trich seen in men and women:

What Causes Trichomoniasis?

Trichomoniasis is caused by a microscopic parasite called Trichomonas vaginalis. The infection spreads mainly through sexual contact with an infected person, including vaginal, anal, or oral sex, as well as direct genital-to-genital contact. It can be transmitted from men to women, women to men, and between same-sex partners. Because many infected people do not develop any symptoms, they may unknowingly pass the infection to their sexual partners.

Trichomoniasis is not caused by poor personal hygiene or a urinary tract infection (UTI), and it does not transmit through hugging, kissing, handholding, or sharing food or drinks.

Risk Factors of Trichomoniasis

Any person can contract trichomoniasis if they come into contact with the parasite that causes it. However, the following factors can increase the likelihood of developing trichomoniasis:

• Gender: Trichomoniasis is more commonly diagnosed in women than in men.

• Unprotected Sex: Not using condoms during sexual intercourse increases the risk of acquiring the infection.

• Multiple Sexual Partners: Having multiple sexual partners can increase the chances of coming into contact with an infected person.

• Previous Sexually Transmitted Infections (STIs): A history of trichomoniasis or other STIs may make a person more susceptible to future infections.

• Vaginal Douching: Cleaning the vagina with water or other fluids (also called douching) can disrupt its natural balance, increasing the risk of infection.

• Alcohol or Drug Misuse: Excessive alcohol consumption or recreational drug use may lead to behaviours that increase the risk of sexually transmitted infections.

What are the Complications of Trichomoniasis?

If left untreated, trichomoniasis can lead to other health complications, particularly by increasing the risk of other infections and pregnancy-related problems. These include:

• Higher Risk of HIV Infection: Trichomoniasis causes inflammation in the genital area, making it easier to acquire or transmit HIV. People living with both HIV and trichomoniasis are also more likely to pass the virus to their sexual partners.

• Pregnancy Complications: During pregnancy, untreated trichomoniasis can increase the chances of premature birth, low weight of the baby, and early rupture of the membranes. In some cases, the infection may also be passed to the baby during childbirth.

• Pelvic Inflammatory Disease (PID): In women, the infection can spread to the upper reproductive organs, leading to PID, which can cause extreme pelvic pain, infertility, or an ectopic pregnancy.

• Other Genital and Urinary Infections: Trichomoniasis has been associated with conditions such as bacterial vaginosis, inflammation of the prostate (prostatitis), epididymitis, and bladder inflammation (cystitis).

• Long-Lasting Infection: Without appropriate treatment, trichomoniasis may persist for several months or even years, increasing the likelihood of complications and ongoing transmission to others.

When Should I See My Healthcare Provider?

You should consult your healthcare provider if you notice:

• Unusual vaginal or penile discharge

• Foul-smelling discharge

• Genital itching or irritation

• Redness or swelling around the genitals

• Pain during sexual intercourse.

It is also important to seek medical advice if you do not have any symptoms, but are at risk of getting an infection, as trich often causes no symptoms. The risk factors can be having unprotected sex or finding out that your partner has been diagnosed with the condition.

How is Trichomoniasis Diagnosed?

As per the standard WHO method, Trichomoniasis is diagnosed through a combination of a medical examination and laboratory tests to confirm the presence of the parasite.

How is Trichomoniasis Treated?

Trichomoniasis is treated with antibiotics that eliminate the parasite responsible for the infection. Here is what treatment typically involves:

• Single Dose Treatment: A single larger dose of an antibiotic such as metronidazole or tinidazole may be prescribed, which is effective in curing up to 95% of cases.

• Course of Antibiotics: Alternatively, a lower dose of metronidazole or tinidazole may be prescribed to be taken twice daily over seven days. It is important to complete the full course even if symptoms begin to improve earlier.

• Second-Line Treatment: In cases where treatment does not work the first time, alternative antibiotic regimens are available and should be discussed with a healthcare provider.

Can Trichomoniasis be Prevented?

Yes, trichomoniasis can be prevented by taking a few simple precautions. Here is an overview:

• Safe Sexual Intercourse: Correct and consistent use of condoms during sexual activity is one of the most useful ways to reduce the risk of trich and other sexually transmitted infections.

• Periodic Tests: If you are sexually active, regular diagnostic tests for trichomoniasis and other sexually transmitted infections can help identify infections early, even if you do not have symptoms.

• Prompt Treatment: If you are diagnosed with trichomoniasis, start treatment as advised by your healthcare provider to reduce the possibility of further complications and transmission to others.

Trichomoniasis and Pregnancy

Trichomoniasis during pregnancy increases the risk of early labour and of having a baby with low birth weight. In some cases, the infection may also be passed to the baby during childbirth, and it may increase the mother's risk of developing sepsis after delivery.

Fortunately, healthcare providers generally consider antibiotic treatment with metronidazole safe during pregnancy and while breastfeeding. However, other medicines such as tinidazole and secnidazole are usually avoided during pregnancy because their safety has not been established.

What is the Prognosis of Trichomoniasis?

The outlook for trichomoniasis is very positive in most cases. The infection can usually be cured completely with antibiotic treatment. Most people recover fully after completing the prescribed course of antibiotics, with symptoms usually improving within a few days. However, following the treatment plan carefully is important to ensure the infection clears completely and to reduce the risk of complications.

Recovery from trichomoniasis does not provide lifelong immunity. Around one in five people become infected again within three months, making reinfection relatively common.

Does Health Insurance Cover Trichomoniasis?

Standard health insurance plans generally do not cover preventive screening or routine testing for sexually transmitted infections (STIs), including trichomoniasis. Most health insurance policies provide coverage only when hospitalisation for at least 24 consecutive hours is medically necessary. In such cases, eligible expenses such as hospitalisation charges, diagnostic tests, prescribed medicines, ambulance services, and pre- and post-hospitalisation expenses are covered according to the policy terms and conditions.

Trichomoniasis is usually treated successfully with a course of oral antibiotics and rarely requires hospital admission. Thus, the regular health insurance policies generally do not cover treatment costs. Some insurers offer OPD benefits as optional add-ons or specialised health insurance plans that cover the diagnosis and treatment of sexually transmitted infections.

Read through your policy documents carefully to understand what coverage, exclusions and optional benefits are available.
