Human papillomavirus (HPV) is the most common sexually transmitted infection
If you are sexually active, you can get HPV, even if you have had sex with only one person. You also can develop symptoms years after having sex with someone who has the infection. This makes it hard to know when you first got it. Get vaccinated. The HPV vaccine is safe and effective. It can protect against diseases (including cancers) caused by HPV when given in the recommended age groups.
Chlamydia trachomatis/Neisseria gonorrhoeae
Chlamydia is a common sexually transmitted infection (STI) caused by bacteria. You might not know you have chlamydia because many people don’t have signs or symptoms, such as genital pain and discharge from the vagina or penis. Chlamydia trachomatis affects mostly young women, but it can occur in both men and women and in all age groups. It’s not difficult to treat, but if left untreated it can lead to more-serious health problems.
Trichomonas vaginalis and Mycoplasma genitalium
Trichomonas vaginalis and Mycoplasma genitalium are highly prevalent sexually transmitted pathogens that may be asymptomatic or may cause cervicitis and pelvic inflammatory disease in women and urethritis in men.
