OBJECTIVE: To investigate asymptomatic shedding from the uterine cervix of five human herpes viruses: cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV) type 1 and type 2 and varicella zoster virus (VZV), in young women.
DESIGN: A descriptive study.
SETTING: Sahlgrenska University Hospital.
POPULATION: Three hundred and five young, healthy Swedish women.
METHODS: Cervical specimens were analyzed for the presence of viral DNA with a quantitative real-time PCR assay.
MAIN OUTCOME MEASURES: Detection of viral DNA.
RESULTS: Viral DNA was detected in 66 (21.6%) of the cervical samples. The most common findings were CMV DNA, detected in 35 (11.5%), and EBV DNA, found in 32 (10.5%) of the women. HSV-1 DNA was detected in 5 (1.7%) and HSV-2 DNA in 4 (1.4%), but VZV DNA was not found. The estimated DNA level for the detected viruses was similar with a mean DNA quantity of 2.6 log genome equivalents (Geq)/mL for CMV (range 1.7-4.3), 2.5 log Geq/mL for EBV (range 1.7-4.7), 2.4 log Geq/mL for HSV-1 (range 1.7-3.5) and 2.6 log Geq/mL for HSV-2 (range 1.7-4.1). The simultaneous presence of DNA from two or more herpes viruses was detected in eight specimens.
CONCLUSIONS: Asymptomatic shedding of CMV and EBV from the uterine cervix was found in one-fifth of young women. In four of the cervical samples; two with EBV, one with CMV, one with HSV-2, high amounts of viral DNA (>4 log Geq/mL) were detected suggesting a greater risk of transmitting the virus perinatally or sexually.
