STD vs STI  

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs), are very common. Millions of new infections occur every year in the United States. STDs pass from one person to another through vaginal, oral, and anal sex. They also can spread through intimate physical contact like heavy petting, though this is not very common. 

A sexually transmitted infection (STI) is a virus, bacteria, fungus, or parasite people can get through sexual contact. Many STIs have no symptoms, so people can have an infection but not know it. A sexually transmitted disease (STD) develops because of an STI and the term implies that the infection has led to some symptom of disease. People sometimes use the terms in one another’s place. The primary goal of public health and healthcare is to prevent and treat infections before they develop into disease. As a result, many – including CDC – are using the term STI more often. However, STD is still used when referring to data or information from sources that use the term. (Information from CDC’s STD Diseases & Related Conditions: What are STDs?

Common STI Symptoms 

Sexually transmitted infection symptoms usually appear after two weeks but could start earlier, arrive later, or not be present at all. STIs can have a range of symptoms, or even no symptoms at all. That's why sexually transmitted infections may go unnoticed until a person has complications or a partner is diagnosed.   

STI  symptoms might include: 

  • Sores or bumps on the genitals or in the oral or rectal area 
  • Painful or burning urination 
  • Discharge from the penis 
  • Unusual or odorous vaginal discharge 
  • Unusual vaginal bleeding 
  • Pain during sex 
  • Sore, swollen lymph nodes, particularly in the groin but sometimes more widespread 
  • Lower abdominal pain 
  • Fever

Getting Tested

If you are sexually active, have a new sexual partner or if you have more than one sex partner, it is important to get tested. You may get or give an infection to your sex partner(s) without ever having symptoms. If you have symptoms, it is especially important to stop having sex and get tested. 

The only way to know if you have an STI or STD is to get tested. If you have a doctor, ask about testing and treatment options. You can also contact the Snohomish County Health Department for testing options. 


  • Call your provider to schedule an appointment to be tested or contact the Snohomish County Health Department  
  • Stop having sex until you and your partner(s) get tested 
  • Tell your partner(s) 


Expedited Partner Therapy (EPT) is a way the Snohomish County Health Department or your doctor can treat the sex partners of people infected with chlamydia or gonorrhea without requiring partners to be tested or even seen by a healthcare provider. EPT is available at no cost. Please call 425-339-5261 if you or a partner have tested positive for chlamydia and/or gonorrhea and would like EPT. 

Our goal is to prevent future illness for you and the spread to others. Doctors, hospitals, and labs are required by law to report certain diseases, including certain sexually transmitted diseases. When we learn of someone diagnosed with chlamydia, gonorrhea, and/or syphilis, our disease intervention specialists may contact you (while being careful to respect your privacy) to ensure you and your sex partner(s) receive appropriate testing and treatment.
