Cervicitis Causes and Diagnostic Considerations

Primary Infectious Causes

• The Centers for Disease Control and Prevention recommends that Chlamydia trachomatis and Neisseria gonorrhoeae are the most common causes of cervicitis, particularly in high-risk populations 1, 2, 3
• Trichomonas vaginalis can cause cervicitis, especially in women with trichomoniasis 1, 2
• Herpes simplex virus type 2 (HSV-2) can cause cervicitis, especially during primary infection 1, 2, 5

Non-Infectious Causes

• Frequent douching is associated with persistent cervicitis, according to the Centers for Disease Control and Prevention 1, 5
• Chemical irritants and persistent abnormality of vaginal flora may contribute to cervical inflammation 5
• Idiopathic inflammation in the zone of ectopy can occur without an identifiable cause 5

Critical Clinical Context

• In most cases of cervicitis, no organism is isolated, particularly in women over 30 years old, as noted by the Centers for Disease Control and Prevention 1, 2, 4
• High-risk populations (age <25 years, new or multiple sex partners, unprotected sex) are more likely to have chlamydia or gonorrhea 5
• Low-risk populations (older age, stable relationships) are less likely to have identifiable STD pathogens 1, 5

Diagnostic Implications

• The Centers for Disease Control and Prevention recommends that all women with new cervicitis should be assessed for pelvic inflammatory disease and tested for both chlamydia and gonorrhea using nucleic acid amplification tests (NAATs) 1, 2, 5
• Evaluation for bacterial vaginosis and trichomoniasis is warranted, as these conditions should be treated if present, according to the Centers for Disease Control and Prevention 1, 5
