Sexually Transmitted Disease (STD) , Chlamydia infection

Sexually transmitted disease (STD) is of concern, when you travel in foreign countries.

I am going to explain several STDs from today.

Today’s topic is Chlamydia infection.

Approximately 30% of Japanese female sex workers are infected with Chlamydia.

13.1% of Japanese female high school students and 6.7% of Japanese male students are asymptomatic Chlamydia carrier, respectively.

Thus the risk of Chlamydia infection is high when you have sexual intercourse with Japanese women and men.

Chlamydia infection is also noted in the Pharyngeal region and oral sex is also of some risk.


The majority of female Chlamydia infection is asymptomatic. The uterine cervix is most affected in women and the infection can cause pelvic inflammatory disease, which leads to infertility and chronic pain. It might increase the risk of cervical cancer.

Dysuria-pyuria syndrome due to Urethritis is another consequence of Chlamydia infection in female.

For male, Chlamydia infection causes Urethritis, nonetheless 40-96 % of Chlamydia Urethritis is asymptomatic in men.

The typycal symptom is a mucoid or waterly discharge from Urethra and dysuria. The discharge is sometimes scant so that men only notice stained underwear in the morning.

The incubation period is 5-10 days after the sexual contact.

Chlamydia infection also causes Epidymitis , Prostatitis and Proctitis which often needs a long term therapy.

Use of condom is the best practice in order to avoid Chlamydia infection.

Plastic wrap is useful when you make a direct contact with genital area using your lip.

If you have symptom or concern, you should consult a specialist. Antibiotics is effective to treat Chlamydia infection.
