Trichomoniasis in Bali Explained: Risks and Testing Options

Trichomoniasis is one of the most common parasitic STDs in Bali, yet it often goes unrecognized due to its subtle or mistaken symptoms. Many individuals carry the infection without knowing it, making routine screening especially important in sexually active communities.

In a setting like Bali, where short-term relationships are common, the risk of undiagnosed infections increases. Knowing how trichomoniasis in Bali spreads and when to seek treatment can help reduce discomfort and prevent reinfection.

What is Trichomoniasis?

Trichomoniasis is caused by Trichomonas vaginalis, a microscopic single-celled parasite that infects the genital and urinary tracts. It typically lives in the vagina, vulva, urethra, or penis. Because it thrives in moist environments, the parasite is transmitted through direct sexual contact, most commonly during vaginal intercourse.

Unlike many other STIs, trichomoniasis is caused by a protozoan parasite, not a bacterium or virus. The infection can be easily treated once detected—but the challenge lies in detecting it early, as many individuals carry the parasite without symptoms.

What Are the Symptoms of Trichomoniasis?

Trichomoniasis is often referred to as a “silent” infection because around 70% of infected individuals do not experience any noticeable symptoms. When symptoms do occur, they usually appear within 5 to 28 days after exposure. 

These symptoms can be subtle, intermittent, or confused with other infections, which makes trichomoniasis easy to miss without regular testing.

In Women:

• Unusual vaginal discharge
  This discharge may appear thin, frothy, and yellow-green in color. It is often accompanied by a strong, unpleasant odor. The change in discharge is caused by the parasite disrupting the natural balance of vaginal bacteria.
  
  
• Genital itching or irritation
  Women may feel persistent itching or burning around the vaginal opening or vulva. This irritation is caused by inflammation of the vaginal tissues due to the body’s immune response to the parasite.
  
  
• Pain during urination (dysuria)
  The infection can inflame the urethra, leading to a sharp or burning sensation when urinating. This is sometimes mistaken for a urinary tract infection.
  
  
• Pain during intercourse
  Vaginal tissues may become inflamed or sensitive, making sexual activity painful or uncomfortable.
  
  
• Redness or swelling of the vaginal area
  This is a visible sign of irritation, and may also be felt as a warm or raw sensation in the genital area.
  
  

In Men:

• Burning after urination or ejaculation
  This is often a result of irritation or inflammation of the urethra caused by the parasite.
  
  
• Mild penile discharge
  Men may notice a small amount of clear or whitish fluid from the penis, although this symptom is often subtle.
  
  
• Itching or irritation inside the penis
  This is typically felt near the tip of the penis and is usually mild.
  
  
• No symptoms at all
  Most men with trichomoniasis do not show any signs of infection, which makes it easier for the parasite to spread unknowingly.
  
  

Because symptoms can be absent or confused with other conditions, routine STD testing is the most reliable way to detect and treat trichomoniasis early—before complications or transmission occur.

How is Trichomoniasis Transmitted?

Trichomoniasis is transmitted through direct genital-to-genital contact, particularly during vaginal sex. The parasite moves between individuals via exposure to genital fluids, infecting the urethra, vagina, or vulva. While transmission can occur between people of any gender, it is especially common in heterosexual encounters.

Main Modes of Transmission:

a. Penis-to-vagina intercourse
This is the most common way trichomoniasis is transmitted. The parasite moves through genital fluids during unprotected vaginal sex. Both men and women can transmit or acquire the infection this way—even if no symptoms are present.

b. Vagina-to-vagina contact
The infection can also spread between women during genital contact, particularly if vaginal fluids are exchanged.

c. Shared sex toys
Using sex toys that are not cleaned properly or not covered with a new condom between uses can pass the parasite from one partner to another. This applies to both heterosexual and same-sex partners.

Although trichomoniasis spreads through intimate contact, it cannot be transmitted through kissing, oral or anal sex, or by sharing toilet seats, towels, or clothing. The parasite cannot survive long outside the body and requires a moist, warm environment—like the vaginal or urethral lining—to remain active. 

How is Trichomoniasis Diagnosed?

Diagnosing trichomoniasis is relatively simple, but it often requires proactive testing because many infected individuals have no symptoms. Diagnosis can be made during a routine pelvic exam in women or STD screening in both men and women.

Common methods include:

• Microscopic examination (wet mount): A sample of vaginal or urethral fluid is viewed under a microscope to look for the parasite. While quick, this method isn’t always accurate if the parasite is present in low numbers.
  
  
• Antigen tests or rapid tests: These detect proteins from the parasite and are more sensitive than microscopy. Results can often be available the same day.
  
  
• NAAT (nucleic acid amplification test): This is the most sensitive and reliable method. It detects the parasite’s genetic material in urine or swab samples. NAAT is recommended for routine screening, especially in high-risk groups or during pregnancy.
  
  

Because trichomoniasis can be easily confused with other infections, such as chlamydia or bacterial vaginosis, laboratory testing remains the only way to confirm the diagnosis. 

What Are the Complications of Trichomoniasis?

When left untreated, trichomoniasis can lead to serious health complications, particularly for women. The parasite doesn’t just cause discomfort—it can weaken genital tissue, disrupt immune defenses, and increase the likelihood of co-infections.

In Women:

• Pelvic Inflammatory Disease (PID): Untreated trichomoniasis can contribute to PID—a condition where infection spreads to the uterus, fallopian tubes, or ovaries. PID can cause infertility, chronic pelvic pain, and increase the risk of ectopic pregnancy.
  
  
• Complications during pregnancy: Pregnant women with trichomoniasis have a higher risk of preterm delivery, premature rupture of membranes, and delivering babies with low birth weight.
  
  
• Increased risk of HIV infection: Trichomoniasis causes inflammation and micro-tears in genital tissues, making it easier to acquire or transmit HIV if exposed. 
  

In Men:

• While complications in men are less common, untreated infections can lead to chronic urethritis (inflammation of the urethra) and may contribute to prostatitis (inflammation of the prostate gland).
  
  

Additionally, both men and women with untreated trichomoniasis may experience emotional distress, relationship strain, and lowered sexual wellbeing due to symptoms and stigma.

Treatment for Trichomoniasis

The good news about trichomoniasis is that it is completely curable with medication. Once diagnosed, the infection can usually be treated with a single dose or short course of oral antibiotics. 

These medications are highly effective in killing the parasite. The treatment is usually given as a single large dose or over a five- to seven-day course, depending on the individual’s health, symptom severity, or whether they have been infected before. Here are some key considerations during treatment that you should be aware of:

• Avoid alcohol while taking oral antibiotics for at least 24–72 hours after finishing the medication. Combining alcohol with these drugs can cause nausea, vomiting, cramps, and headaches.
  
  
• Both partners must be treated at the same time, even if only one of them has symptoms.
  
  
• Avoid sexual activity until seven days after finishing treatment and all symptoms have cleared. Having sex too soon can lead to reinfection or failure of treatment.
  
  

In all cases, completing the full course of treatment exactly as prescribed is key to recovery.

How Can You Prevent Trichomoniasis?

Because the infection is often asymptomatic, many people don’t know they’re carrying it—which means routine prevention efforts are key to stopping its silent spread. Here are some of the most effective ways to protect yourself and your partner:

• Get tested regularly—even without symptoms
  The most reliable way to catch the infection early is through routine STD testing. If you’re in Bali and looking for a trusted, confidential place to screen for STIs, Unicare Clinic offers comprehensive STD test services designed for both locals and international visitors.
  
  
• Disinfect sex toys or use protection
  Wash toys with soap and water between uses, and cover them with a new condom if used between partners. Shared toys are a lesser-known but possible route for trichomoniasis transmission.
  
  
• Have open conversations with partners
  Honest communication about sexual health history, testing, and preferences can go a long way in preventing misunderstanding and infections.
  
  
• Avoid douching
  Douching can disrupt the vaginal microbiome, making it easier for infections like trichomoniasis to take hold.
  
  

By being informed and proactive—and choosing reliable testing services like those at Unicare Clinic—you take control of your health and contribute to safer, more confident connections.
