Final answer:
Chlamydia and HPV are common STIs among adolescent females, with chlamydia being the most commonly reported bacterial STI and HPV being the most prevalent STI overall in the U.S. Regular screening and vaccination are key preventive measures.
Step-by-step explanation:
Sexually transmitted infections (STIs) such as chlamydia and human papillomavirus (HPV) are particularly prevalent among adolescent females. Chlamydia, caused by the bacterium Chlamydia trachomatis, is the most common bacterial STI in the United States. This infection is most frequently diagnosed in young people, especially between the ages of 15 and 24. Females are more often affected due to differences in screening practices. Chlamydia can have serious long-term health implications if not treated, including pelvic inflammatory disease (PID), ectopic pregnancy, and infertility.
HPV is even more widespread and is the most common STI in the United States, affecting a significant number of sexually active individuals. Although HPV infections cannot be cured, vaccination with Gardasil® can prevent most HPV infections in females, reducing the risks of cervical cancer. Both chlamydia and HPV are preventable and manageable with appropriate medical care and screening.
Routine screening for chlamydia is recommended for sexually active females under 25 and those with other risk factors. These STIs can often be asymptomatic, making regular testing crucial for early detection and treatment to prevent more serious health consequences.
