Sexually transmitted diseases (STDs), also called sexually transmitted infections (STIs), are illnesses spread by sexual contact. Many People aren’t aware they have an STD. Symptoms may not be present or obvious. Infected people can spread STDs without knowing it.

There are many types of STDs. While most STDs can be treated, all STDs can be prevented. The most common are:

• Chlamydia.
• Gonorrhea.
• Herpes.
• Syphilis.

Providers must report STD cases.

Healthcare providers and facilities must report HIV/AIDS and most other STDs within 3 business days.

Fax the appropriate reporting form to 360-452-4492.

• HIV/AIDS case report form.
• Confidential STD Case Report Form

For more information, see our reporting notifiable conditions page or call 360-417-2274.

We encourage providers to give EPT.

Expedited partner therapy (EPT) helps control the spread of infection. EPT is giving medicine to an infected person’s sex partners without examining them first. This helps prevent reinfection of the patient and prevents further transmission by partners.

EPT is permissible in Washington in many cases of Chlamydia and Gonorrhea. Providers can find out more about EPT from the Centers for Disease Control and Prevention (CDC), and by contacting the Health Department.
