If you have health insurance, you can get tested and treated for STIs from your primary medical provider or clinic.


Many people with an STI have no symptoms. Those who have symptoms may experience:

  • Unusual discharge from the penis or vagina
  • Sores or warts on the genital area
  • Burning while urinating
  • Itching and redness in the genital area
  • Anal itching, soreness or bleeding

Check the following links for information on specific STIs:


  • STIs caused by bacteria such as gonorrhea, syphilis and chlamydia are curable with antibiotics.
  • Genital herpes and genital warts are examples of STIs caused by viruses and are not curable, but treatment helps control outbreaks and reduces spread of disease.
  • There is no cure for HIV, but medications can help people with HIV live longer, healthier lives.
  • Early treatment of STIs prevents serious medical complications and helps reduce spread of disease.
  • If you have an STI, your partner(s) also need to be tested and treated. PHMDC can help. Call (608) 243-0411 for more information.
