Overview
The incidence and prevalence of cervicitis depends on the study population. The prevalence of cervicitis is estimated to be 18,000 per 100,000 women diagnosed with gonococcal infection.[1] Cervicitis is relatively more prevalent in HIV-positive women than non-HIV positive women.[2] Among this population, the prevalence of cervicitis is estimated to be 7,400 per 100,000 women diagnosed with HIV infection.[3] The overall prevalence of nongonococcal cervicitis is higher than gonococcal cervicitis.[4] Chlamydia cervicitis is four to five times more prevalent than gonococcal cervicitis.[5][4] However, co-infection of gonococcal and chlamydia cervicitis is higher in PID than in cervicitis.[5] Cervicitis commonly follows the pattern of age prevalence of sexually transmitted infections with the highest incidence among women aged 15-24.[6][7][8] There is no racial predilection to developing cervicitis. The prevalence of cervicitis is higher in under-served communities and developing countries.[9][10]
Epidemiology and Demographics
Prevalence and Incidence
The incidence and prevalence of cervicitis depends on the study population.
The prevalence of cervicitis is estimated to be 18,000 per 100,000 women diagnosed with gonococcal infection.[1] The prevalence of cervicitis ranges from 7,600 to 24,900 per 100,000 female sex workers. The broad range is due to variation in demographic location.[11][12]
Cervicitis is relatively more prevalent in HIV-positive women than non-HIV positive women.[2] Among this population, the prevalence of cervicitis is estimated to be 7,400 per 100,000 women diagnosed with HIV infection.[3] Screening and treatment of M. genitalium among HIV-infected individuals may be needed to improve cervical health and reduce morbidity.[3] The overall prevalence of nongonococcal cervicitis is higher than gonococcal cervicitis.[4] Chlamydia cervicitis is four to five times more prevalent than gonococcal cervicitis.[5][4] However, co-infection of gonococcal and chlamydia cervicitis is higher in PID than in cervicitis.[5]
Age
Cervicitis commonly follows the pattern of age prevalence of sexually transmitted infections with the highest incidence among women aged 15-24.[6][7][8]
Race
There is no racial predilection to developing cervicitis.
Developed and Developing Countries
The prevalence of cervicitis is higher in under-served communities and developing countries.[9][10]
