What Are STDs/STIs?

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs) are infections that are passed between partners during sexual activity. Some STIs can have serious long-term and even life-threatening consequences, while others may not cause symptoms and therefore go undetected. Bacterial STIs, such as chlamydia, syphilis, and gonorrhea can be treated with antibiotics. Other STIs, such as HIV, can’t be cured but can be managed and monitored closely with a healthcare provider.
