A sexually transmitted infection (STI) is an infection that is spread through sexual contact with an infected individual. STIs can be caused by bacteria, viruses, or parasites and can be transmitted through vaginal, anal, or oral sex. Common examples of STIs include chlamydia, gonorrhea, syphilis, HIV, herpes, and HPV. Symptoms of STIs can vary widely depending on the specific infection but may include genital sores, discharge, pain during urination, and flu-like symptoms. However, some STIs may not show any symptoms at all, making it crucial to get tested regularly, especially if you are sexually active with multiple partners. STIs can have serious health consequences if left untreated, including infertility, chronic pain, and an increased risk of certain cancers. Using condoms consistently and correctly, getting tested regularly, and communicating openly with sexual partners are important steps in preventing the spread of STIs and maintaining sexual health.
