Chlamydia is a bacterial infection that’s easily cured with antibiotic medicine. It’s one of the most common STDs, and most people who have chlamydia don’t show any symptoms. Chlamydia is spread through vaginal, anal, and oral sex. The infection is carried in semen (cum), pre-cum, and vaginal fluids. Chlamydia can infect the penis, vagina, cervix, anus, urethra, eyes, and throat.


HPV stands for human papillomavirus. It’s the most common sexually transmitted infection. HPV is usually harmless and goes away by itself, but some types can lead to cancer or genital warts. About 40 kinds can infect your genital area — your vulva, vagina, cervix, rectum, anus, penis, and scrotum — as well as your mouth and throat. These kinds of HPV are spread during sexual contact.

Gardisil (HPV) Vaccine

Gardisil is effective in protecting against HPV infection and is recommended before sexual activity and before age 15 years, if possible. This is available at our Family Planning Clinics, School Based Health Centers and Immunization Clinics for up to age 19 years. Talk with your healthcare provider about options.

Genital Warts

Genital warts are common and are caused by certain types of HPV. Genital warts can be annoying, but they’re treatable and aren’t dangerous. Genital warts show up on the skin around your genitals and anus. They’re caused by certain types of human papillomavirus (HPV). You might’ve heard that some types of HPV can cause cancer, but they’re NOT the same kinds that give you genital warts.


Gonorrhea is a common bacterial infection that’s easily cured with antibiotic medicine. It’s sexually transmitted, and most people with gonorrhea don’t have symptoms. Gonorrhea is a very common sexually transmitted infection, especially for teens and people in their 20s. Gonorrhea is sometimes called “the clap” or “the drip.”


Herpes is a common virus that causes sores on your genitals and/or mouth. Herpes can be annoying and painful, but it usually doesn’t lead to serious health problems. Herpes is a super-common infection that stays in your body for life. More than half of Americans have oral herpes, and about 1 out of 6 Americans has genital herpes.


Syphilis is a really common STD. Syphilis is spread through vaginal, anal, and oral sex. Syphilis is easily cured with antibiotic medicine, but it can cause permanent damage if you don’t get treated. Syphilis is spread from sexual skin-to-skin contact with someone who has it. You get it when your vulva, vagina, penis, anus, or mouth touches someone’s syphilis sores — usually during sex.


HIV is the virus that causes AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. HIV and AIDS are not the same thing. And people with HIV do not always have AIDS. HIV is carried in semen (cum), vaginal fluids, blood, and breast milk. The virus gets in your body through cuts or sores in your skin, and through mucous membranes (like the inside of the vagina, rectum, and opening of the penis).

We offer PrEP management for high risk persons.


STD Booklet

STDs are diseases that are spread through sexual intimacy or sometimes skin-to-skin contact. The STD booklet (PDF) explains different types of STDs. It describes how they are spread, treated and, most importantly, prevented.
