General practice update: chlamydia infection in women.

The prevalence of cervical Chlamydia trachomatis infection in general practice populations ranges between 2% and 12%. Untreated infection can cause pelvic inflammatory disease, tubal infertility and ectopic pregnancy. These risks are increased by cervical invasive procedures, especially termination of pregnancy. However, most women with chlamydia infection have no symptoms. General practitioners and practice nurses carrying out pelvic examinations should have facilities for taking endocervical specimens for chlamydia. Routine chlamydia screening, should be considered if the local prevalence of infection is over 6%. Otherwise chlamydia testing should be offered to women requesting termination of pregnancy and to those who have risk factors: aged less than 25 years, absence of barrier contraception, recent change of sexual partner, vaginal discharge, friable cervix or sterile pyuria. Women found to have chlamydia infection need appropriate antibiotics, advice about contact tracing and referral to a genitourinary medicine clinic. Good communication between general practitioners and genitourinary physicians is essential. Both general practitioners and practice nurses have an important role to play in reducing the prevalence of cervical chlamydia infection and its potentially devastating consequences.
