Too Much Screening for Chlamydia?

Annual screening for Chlamydia trachomatis is now widely recommended for all sexually active women aged 25 years or younger as a measure to prevent pelvic inflammatory disease (PID). However, a recent study of 2,529 sexually active female students, conducted by researchers from the University of London, Imperial College, King’s College, Centre for Infections, and St. George’s Hospital, all in London, England, disputes the effectiveness of this recommendation.
