April 20, 2021 - 1:21 PM The Canadian Task Force on Preventive Health Care is recommending that routine screening for chlamydia and gonorrhea be extended to sexually active people under age 30. The new guidelines published in the Canadian Medical Journal on Tuesday expand the current practice of annually testing patients up to age 25. The authors say the recommendation reflects rising rates of chlamydia and gonorrhea among people aged 25 to 29 over the past two decades. They say the reported rate of chlamydia among people aged 15 to 29 is between one and 1.9 per cent, but the true prevalence could be as high as five to seven per cent.
