Chlamydia is caused by the Chlamydia Trachomatis bacteria. It is one of the most common bacterial STIs globally. 

It predominantly affects sexually active individuals, particularly at young age. 

The infection is often asymptomatic, making it challenging to detect without proper screening.

Symptoms and complications

When symptoms occur, they include painful periods, itching around private parts, and pain during urination. 

If left untreated, Chlamydia can contribute to severe complications such as Pelvic Inflammatory Disease (PID). 

This may cause chronic pelvic pain, infertility, or ectopic pregnancy. 

Additionally, pregnant individuals with Chlamydia can transmit the infection to their newborn during childbirth. 

It can cause eye infections or Pneumonia in the infant.

Diagnosis and treatment

Healthcare providers typically conduct diagnostic tests such as Nucleic Acid Amplification Tests (NAATs).

This test helps confirm the presence of Chlamydia Trachomatis. 

Treatment usually consists of antibiotics, most commonly Azithromycin or Doxycycline. 

Alternative antibiotics, such as Amoxicillin and Erythromycin, may also be considered.

Trichomoniasis is caused by a protozoan parasite known as Trichomonas Vaginalis. 

This STI is more prevalent in women than in men. It is often asymptomatic.

Symptoms and complications

Symptoms of Trichomoniasis may include itching, redness in the genital area, burning, and pain during urination and sexual intercourse.

Trichomoniasis frequently causes vaginal discharge in females. In males, it is linked to an increased risk of epididymitis, prostatitis, and reduced sperm motility.

Pregnant individuals with Trichomoniasis may experience preterm birth or deliver low birth-weight babies.

Diagnosis and treatment

Diagnosis involves microscopic examination of genital swabs or urine samples. This will help detect the presence of the parasite.

Treatment usually consists of the prescription drug Metronidazole or Tinidazole. 

These drugs help effectively eliminate the infection.

It is essential to refrain from drinking throughout the treatment and for at least three days after the last dose. 

Preventive tips for Chlamydia and Trichomoniasis

Preventing STIs, including Chlamydia and Trichomoniasis, involves a proactive approach to reduce the risk of infection. 

Here are key preventive strategies:

Testing with partners

Partners may consider getting tested together.

Honest and open communication among couples about STI testing is crucial.  

Being aware of each other’s STI status is crucial for making informed choices about engaging in intimate activities.

Trichomoniasis recurrence is a serious concern. Shockingly, treated individuals may also experience reinfection within three months. Taking precautions to prevent reinfection is a must.

Safe sex practices

Have consistent and correct use of latex condoms during vaginal, anal, and oral sex.

This can significantly reduce the risk of STI transmission.

Routine screenings

Routine screenings for Sexually Transmitted Infections (STIs), including Chlamydia and Trichomoniasis, are essential.

It is crucial, especially for individuals with multiple sexual partners.


Chlamydia and Trichomoniasis, caused by Chlamydia Trachomatis and Trichomonas Vaginalis, respectively, present significant public health challenges. 

Both infections, often asymptomatic, can manifest symptoms such as painful periods, itching, and pain during urination. 

If left untreated, Chlamydia can contribute to complications like Pelvic Inflammatory Disease, while Trichomoniasis may result in adverse outcomes such as preterm birth. 

Antibiotics like Azithromycin for Chlamydia and Metronidazole for Trichomoniasis can help address these infections. 

To prevent their spread, routine screenings and consistent condom use play pivotal roles in safeguarding sexual health.
