Sexually transmitted diseases (STDs), also referred to as sexually transmitted infections (STIs), are infections transmitted through sexual contact. Individuals of all ages, both men and women, can contract STDs. Various types of STDs exist, including chlamydia, gonorrhea, genital herpes, human papillomavirus (HPV), and syphilis.

STDs pose a significant concern for several reasons. They have the potential to cause severe health issues, leading to long-term consequences such as infertility, sexual dysfunction in both genders, and, in extreme cases, death. Additionally, STDs can result in social stigma and embarrassment.

The primary method to prevent STDs is through practicing safe sex, which involves using condoms or other barrier methods during sexual activity. If there is a suspicion of having an STD, it is crucial to undergo STD tests and consult with a healthcare provider promptly to initiate appropriate treatment.
