If you have been contemplating the difference between a sexually transmitted infection (STI) and a sexually transmitted disease (STD), you are not alone. A STI is an infection caused by viruses, bacteria, parasites or yeast that is spread through sexual contact involving your genitals, mouth or anus.

Both terms can be used interchangeably however, they do differ very slightly. If you have been diagnosed with a STI, this means you have an infection but might not yet experience any symptoms; or it has not yet transformed into a disease just yet. In sum, the infection is the beginning phase of a sexually transmitted disease. But, if the STI is treated in time a STD could be prevented. It is important to note that not all STIs are treatable.

For example, HPV (Human Papillomavirus) can often leave women symptomless but they may be a carrier of the virus. This would be an example of a STI. However, the moment that virus develops into cervical cancer the women now clinically has a STD.

Are you at risk for a STI?

There are several circumstances that can place their sexual health at risk. These factors may include:

  • Giving or receiving unprotected oral, anal or genital sex (Unprotected means no condom or dental dam is/was being used)
  • If you have a history of STIs
  • Having multiple sexual partners
  • Abusing alcohol, injecting drugs into your body or the abuse of other substances that could impair decision making skills
  • Not having talked to your partner about their sexual past & their health prior to engaging in sexual activity with them
  • Not being up to date on applicable vaccinations such as HPV and hepatitis

Frequently Asked Sexually Transmitted Infection and Disease Questions

  • Is it okay to ask a potential sexual partner to get tested before engaging in sexual activity together?
      • Yes, absolutely! You should keep an open line of communication between you and your sexual partner before engaging in sexual activity with them for the first time.


  • Do condoms prevent STIs?
      • Ensure you and your partner are using condoms EVERYTIME you engage in sexual activity. While condoms are not 100% guarantee that you will not contract a STI, it greatly reduces your overall risk.


  • I am sexually active. How often should I get tested?
      • We recommend a minimum of once per year even if you having safe sex. If you have unprotected sex, we recommend getting tested right away. If you are participating in casual sex, we recommend at least every six months.


  • Can men get HPV?
      • Yes.


  • I have been tested positive for a STI/STD, and I am pregnant. Is my baby at risk?
      • It is possible to pass your infection or disease to your baby. Your doctor may decide that the safest option for delivery is a cesarean, also known as a C-section.


  • What are the treatments for STDs?
      • Most, if not all STDs that are curable, can be treated with a prescribed antibiotic from the medical practitioner at Midwest Express Clinic. If you are pregnant, be sure to let your provider know, as this could change the prescription you are prescribed so that the baby stays safe.
