Women's knowledge of congenital cytomegalovirus: results from the 2005 HealthStyles survey.

BACKGROUND: Congenital cytomegalovirus (CMV) is as common a cause of serious disability as Down syndrome and neural tube defects. When acquired prior to or during pregnancy, CMV can be transmitted transplacentally to the fetus, sometimes causing serious temporary symptoms, permanent disabilities, or both to the child. One way to prevent infection before and during pregnancy is through simple hygienic practices, such as handwashing. METHODS: This study used the 2005 annual HealthStyles survey, a mail survey of the U.S. population aged <18 years, to assess knowledge of congenital CMV. Self-reports by female respondents measured willingness to adopt particular hygienic behaviors to prevent CMV transmission. RESULTS: Only 14% of female respondents had heard of CMV. Among women who reported they had heard of CMV, the largest proportion said they had heard about it from a doctor, hospital, clinic, or other health professional (29%). The accuracy of women's knowledge of what conditions congenital CMV can cause in the fetus was limited. The prevention behaviors surveyed in the present study (i.e., handwashing, not sharing drinking glasses or eating utensils with young children, and not kissing young children on the mouth) appeared to be generally acceptable. CONCLUSIONS: There are prevention behaviors that have the potential of substantially reducing the occurrence of CMV-related permanent disability in children. However, our results suggest that few women are aware of CMV or these prevention behaviors.

The epidemiology and prevention of congenital cytomegalovirus infection and disease: activities of the Centers for Disease Control and Prevention Workgroup.

Perhaps no single cause of birth defects and developmental disabilities in the United States currently provides greater opportunity for improved outcomes in more children than congenital cytomegalovirus (CMV). --Cannon and Davis. BMC Public Health 2005;5:70 Each year in the United States, thousands of children and their families are affected by congenital cytomegalovirus (CMV) infection. More children may be affected by congenital CMV than by other, better known childhood conditions, such as Down syndrome, fetal alcohol syndrome, and spina bifida. The Centers for Disease Control and Prevention (CDC) has formed a Workgroup on Congenital CMV, led by the National Center on Birth Defects and Developmental Disabilities and the National Center on Infectious Diseases. This report provides background on congenital CMV infection and describes the goals and activities of the workgroup for reducing the burden of sequelae of congenital CMV infection.

Knowledge and awareness of congenital cytomegalovirus among women.

BACKGROUND: Congenital cytomegalovirus (CMV) infection is a leading cause of disabilities in children, yet the general public appears to have little awareness of CMV. METHODS: Women were surveyed about newborn infections at 7 different geographic locations. RESULTS: Of the 643 women surveyed, 142 (22%) had heard of congenital CMV. Awareness increased with increasing levels of education (P<.0001). Women who had worked as a healthcare professional had a higher prevalence of awareness of CMV than had other women (56% versus 16%, P <.0001). Women who were aware of CMV were most likely to have heard about it from a healthcare provider (54%), but most could not correctly identify modes of CMV transmission or prevention. Among common causes of birth defects and childhood illnesses, women's awareness of CMV ranked last. CONCLUSION: Despite its large public health burden, few women had heard of congenital CMV, and even fewer were aware of prevention strategies.

Risk of bacterial meningitis in children with cochlear implants.

BACKGROUND: In June 2002, the Food and Drug Administration received reports of bacterial meningitis in patients with cochlear implants for treatment of hearing loss. Implants that included a positioner (a wedge inserted next to the implanted electrode to facilitate transmission of the electrical signal by pushing the electrode against the medial wall of the cochlea) were voluntarily recalled in the United States in July 2002. METHODS: We identified patients with meningitis and conducted a cohort study and a nested case-control investigation involving 4264 children who had received cochlear implants in the United States between January 1, 1997, and August 6, 2002, and who were less than six years of age when they received the implants. We calculated the incidence of meningitis in the cohort and assessed risk factors for meningitis among patients and among 199 controls, using data from interviews with parents and abstracted from medical records. RESULTS: We identified 26 children with bacterial meningitis. The incidence of meningitis caused by Streptococcus pneumoniae was 138.2 cases per 100,000 person-years--more than 30 times the incidence in a cohort of the same age in the general U.S. population. Postimplantation bacterial meningitis was strongly associated with the use of an implant with a positioner (odds ratio, 4.5 [95 percent confidence interval, 1.3 to 17.9], with adjustment for medical, surgical, and environmental factors) and with the joint presence of radiographic evidence of a malformation of the inner ear and a cerebrospinal fluid leak (adjusted odds ratio, 9.3 [95 percent confidence interval, 1.2 to 94.5]). The incidence of meningitis among patients who had received an implant with a positioner remained higher than the incidence among those whose implants did not have a positioner for the duration of follow-up (24 months from the time of implantation). CONCLUSIONS: Parents and health care providers should ensure that all children who receive cochlear implants are appropriately vaccinated and are then monitored and treated promptly for any bacterial infections after receiving the implant.
