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 STDs can have serious long-term and even life-threatening consequences, while others may go undetected due to being asymptomatic. Bacterial STDs, such as chlamydia, syphilis, and gonorrhea can be treated with antibiotics. Other STDs, such as HIV, hepatitis C, and herpes cannot be cured and the infections will remain for life, though the symptoms may be treated by your doctor.
If you are sexually active, always be sure to practice safe sex to drastically reduce your risk of exposure, and test regularly at least once per year, in particular if you are not in a monogamous relationship.
