In Canada, Chlamydia trachomatis (chlamydia) and Neisseria gonorrhoeae (gonorrhea) are the most commonly reported sex ually transmitted bacterial infections (STIs), 1,2 with reported cases in the population increasing annually since 2000. 3 In 2018, reported cases were highest in people aged 15-29 years, with rates of 1.0%-1.9% for chlamydia and 0.2%-0.3% for gonorrhea in this population, 4 while rates among individuals older than 30 years were less than 0.5% for chlamydia and less than 0.2% for gonor rhea. 4 Many infected individuals, however, are asymptomatic or do not seek care, and are not included in reported cases. 3 Taking into account underreporting, the true prevalence of chlamydia in people aged 15 to 29 years may be as high as 5%-7%. [3][4][5][6] Consequences of untreated chlamydia in females can include cervicitis in 10%-20%, 7 pelvic inflammatory disease in 10%-16%, 8,9 infertility in up to 5%, 10 chronic pelvic pain in 3%-8%, 10,11 and ectopic pregnancy in up to 2%. 10 Consequences of untreated gonorrhea may include rates of pelvic inflammatory disease that exceed those for chlamydia. 12 In males, chlamydia may be associ ated with epididymitis in up to 7%, with or without orchitis, 6,13 and, very rarely, infertility. 14 Consequences of chlamydia affect ing both sexes include urethritis in 4% of females and up to 3% of males; 15 pharyngitis; proctitis; reactive arthritis lasting longer than 6 months in 1%-4% (when considering both chlamydia and gonorrhea); 16,17 and disseminated gonococcal infection in less than 1%, which can rarely lead to sepsis, meningitis, endocarditis or osteomyelitis. 18 Screening sexually active individuals for chlamydia and gon orrhea could reduce clinical complications and transmission, but should be done only if benefits from screening exceed harms 19,20 and resource use is justifiable.In Canada, STI screening is most commonly offered oppor tun istically by clinicians in a variety of primary care settings (e.g., family practice, sexual health clinics, school health centres) during visits that may or may not be for sexual health-related
