Insights
Congenital Cytomegalovirus (cCMV) is a common infection impacting infant development. Early screening and intervention are crucial for improving outcomes and reducing long-term health issues.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Cytomegalovirus (CMV) is the most frequent intrauterine infection.
- Congenital CMV (cCMV) can lead to significant long-term sequelae, including sensorineural hearing loss and neurodevelopmental impairment, in up to 25% of affected infants.
- Despite the availability of antiviral therapies and early intervention services, cCMV imposes a considerable economic burden.
Purpose of the Study:
- To evaluate the cost-effectiveness of different screening strategies for congenital CMV.
- To highlight the limitations of targeted screening in identifying at-risk infants.
- To discuss the varied state-based approaches to cCMV screening in the United States.
Main Methods:
- Review of existing studies on the cost-effectiveness of CMV screening.
- Analysis of the efficacy of targeted versus universal screening approaches.
- Examination of current state-based screening policies in the US.
Main Results:
- Both targeted and universal screening for cCMV have demonstrated cost-effectiveness.
- Targeted screening methods often fail to identify a significant number of infants who are at risk for developing cCMV-related sequelae.
- Current screening policies for cCMV in the United States are inconsistent, ranging from universal screening to education-only approaches.
Conclusions:
- Universal screening for cCMV is more effective in identifying at-risk infants compared to targeted screening.
- Standardizing cCMV screening protocols across states is essential for early detection and intervention.
- Implementing effective screening strategies can mitigate the long-term health and economic consequences of congenital CMV infection.
Abstract:
Cytomegalovirus (CMV) is the most common intrauterine infection. While only 10% to 15% of infants display symptoms at birth, 25% of infants with congenital CMV (cCMV) will develop sequelae such as sensorineural hearing loss and neurodevelopmental impairment by the age of 2 years. Although antiviral therapy and early intervention services can improve outcomes for infected infants, cCMV has a substantial economic impact. Studies show that both targeted and universal screenings are cost-effective, but targeted screening misses many infected infants at risk for sequelae. The state-based approach to cCMV screening in the United States varies from universal, targeted, education only to no requirements.
