This is not true. However, although they can be treated, not all can be cured. The WHOTrusted Source explains that eight pathogens make up the vast majority of STIs.

Four of the eight are curable: the bacterial infections syphilis, gonorrhea, and chlamydia, and the parasitic infection trichomoniasis.

The remaining four are viral: hepatitis B, herpes simplex virus (HSV), HIV, and human papillomavirus (HPV). These cannot yet be cured. However, it is worth noting that HPV infections are often clearedTrusted Source by the body naturally.

“Penetrative sex isn’t the only way someone can contract an STI. Oral sex, genital contact, and sharing sex toys are other ways that STIs can be spread,” Dr. Mann told MNT.

Beyond sexual contact, it is also possible to contract an STI from exposure to blood that contains the infectious pathogen, including through sharing needles.

This is another longstanding and entirely incorrect assumption. According to Dr. Mann:

“Anyone, regardless of sexual orientation, race, ethnicity, age, or gender, can contract HIV. If you have HIV and don’t know it, you’re more likely to pass it on. But if you know your status, you can make sure you and your partner(s) are taking steps to stay healthy.”

Dr. Mann underscores the importance of testingTrusted Source, explaining that in many countries, “testing is free, easy, and confidential. You can even do a test in the comfort of your own home.”

“A lot of people pass on STIs to others without even knowing,” said Dr. Mann. “STIs can be spread with symptoms or without.”

Indeed, the WHO explainsTrusted Source that “[t]he majority of STIs have no symptoms or only mild symptoms that may not be recognized as an STI.”

“That is why,” Dr. Mann explained, “it is important to be tested regularly and to use a condom to prevent STIs as much as possible.”

To summarize, STIs are common but preventable. Regular testing and understanding how to keep yourself safe are key to remaining STI-free.
