Chlamydia, also known as chlamydia infection, is the most common sexually transmitted infection (STI) which is caused by bacterium chlamydia trachomatis; and it can affect both men and women. Individuals who have chlamydia more often than not do not have any outward symptoms in the early stages. However, when symptoms start to develop it might take few weeks for the infection to occur. A few symptoms in women might include burning sensation while urinating and/or vaginal discharge. While women might get chlamydia in rectum, cervix, or throat, men might get it rectum, urethra or throat. Men with chlamydia possess symptoms such as burning with urination, pain and swelling in the testicles, and discharge from penis. Moreover, in women the infection might spread to the upper genital tract and thereby leading to pelvic inflammatory disease and that eventually might lead to ectopic pregnancy or infertility. Therefore, even though chlamydia does not show any symptoms initially, it might cause some serious health issues in the later stages, such as preventing the women from getting pregnant or even endangering their pregnancies.

In the United Kingdom, the National Health Service (NHS) focuses on:

Lessening the onward transmission to sexual partners

Avoid the repercussions of untreated infection

Prevent and curb the infection by detecting early and treating the asymptomatic infection

The 25% of the under 25 women every year

Recheck post treatment

A study on chlamydia infection market states that there have been signs that chlamydia causes reactive arthritis, conjunctivitis and urethral inflammation, and particularly in younger men. Approximately 15,000 men develop reactive arthritis owing to chlamydia infection every year in the United States., and nearly 5000 are permanently affected by it. It occurs when one has unprotected sex with someone who suffers from this sexually transmitted infection. The treatment for chlamydia is oral antibiotics which are either given in multiple doses or just one.For women who are sexually active and are not pregnant, must get checked regularly. A few risk factors include inherited chlamydial or any other sexually transmitted disease, multiple sexual partners and/or lack of condom usage.
