Headlines: Ontario‘s Groundbreaking cCMV Newborn Screening: Success in Identifying Infants at Risk
Meta Description: Discover how Ontario’s population-based congenital cytomegalovirus (cCMV) screening program successfully identified over 600 infected newborns, ensuring early intervention and better outcomes.
Ontario’s innovative congenital cytomegalovirus (cCMV) screening program has successfully captured an impressive 97.4% of newborns, totaling 551,034 infants, within its five-year span from 2019 to 2023. Among these, 689 (0.13%) tested positive for cCMV, with 601 (87.2%) undergoing comprehensive assessments for potential long-term effects.
The program’s yield is marked by 96 infants who displayed symptoms, of whom 63 (65.6%) initiated crucial valganciclovir treatment. Notably, 34 (35.4%) of these symptomatic cases had confirmed sensorineural hearing loss, underlining the screening’s imperative role in early identification.
Despite a slightly higher-than-expected rate of negative confirmatory urine tests following positive dried blood spot (DBS) results (9.2%), the program’s success lies in its ability to identify many cases that might otherwise have flown under the radar. Its feasibility and acceptability are further bolstered by the use of routinely collected DBS samples.
Yet, challenges persist. Clinical management, particularly determining the role of magnetic resonance imaging and prescribing antiviral treatment for infants with head ultrasonographic findings of variable severity potentially attributable to cCMV, presents a hurdle to be navigated.
With a demonstrated lower prevalence of cCMV-positive screens than initially projected, the province’s screening program has shone a spotlight on an often overshadowed condition, ensuring earlier intervention and improved outcomes for countless infants.
understanding congenital cytomegalovirus (cCMV) screening is vital for newborn health, and it can help ensure early intervention and improved outcomes for infants.
FAQ
What is congenital cytomegalovirus (cCMV)? cCMV is a viral infection a baby contracts before birth from their mother.
Why is cCMV screening significant? Early detection allows for prompt treatment and potential prevention of long-term complications, such as hearing loss.
* How is cCMV screened for newborns? A dried blood spot sample is collected from the baby’s heel after birth and tested for the presence of the virus.

Ontario’s pioneering cCMV newborn screening program stands as a powerful testament to the transformative potential of proactive healthcare. By identifying over 600 infants at risk, the program has paved the way for early intervention, potentially saving lives and minimizing the long-term impacts of this often-silent virus. This success not only highlights the program’s remarkable effectiveness but also serves as a model for other jurisdictions seeking to implement similar initiatives. Through continued investment, research, and public awareness, Ontario can further solidify its position at the forefront of neonatal healthcare, ensuring that every child has the best possible start in life.
