Common Sexually Transmitted Infections (STIs)


Chlamydia is the most frequently reported bacterial infection in the US. It has the highest prevalence in people aged 24 and younger. If untreated, it can lead to serious complications such as pelvic inflammatory disease (PID).

Human immunodeficiency virus (HIV) is transmitted through contact with certain bodily fluids, often through unprotected sex or injection drug use.

Test: Codman offers patients a self-test kit they can take home or our lab staff can perform a test in the health center. Results are available in a few hours.

Treatment: There is no cure for HIV, but there are medications (oral or injectable) that you can take to live a healthy and long life. It’s vitally important to treat HIV, even if you have no symptoms. The earlier people are treated, the better their outcomes.

Follow Up: We have case managers who work with people living with HIV through the lifespan to ensure that they stay healthy.


Human Papilloma Virus (HPV) is a very common infection. There is a vaccine to prevent HPV infection, and it is recommended that everyone under 26 years get it. If you are older than 26 and would like the vaccine, talk to your medical provider.

Symptoms: Tiny warts on your genitalia. Many times, people cannot see those warts.

Test: A health care provider can usually diagnose the warts by looking at the genital area.

Treatment: Treatment depends on what health issues the patient experiences. Your provider can discuss treatment options.


Syphilis is a systemic infection that can affect any part of the body. It is more prevalent in men who have sex with men.

Symptoms: Early infection can cause genital ulcers or a rash.  If it’s not treated it can remain in the body and cause symptoms decades after infection.

Test: Codman lab staff will draw blood for the test.

Treatment: Antibiotic injection

Follow Up: Providers recommend coming back for another test three to six months after treatment.


Trichomoniasis is very common and can persist for years if not treated.
