Winnipeg, Manitoba – In a significant step forward for infant health, Manitoba has expanded its universal newborn screening program to include congenital cytomegalovirus (cCMV), a viral infection that can lead to serious long-term disabilities. The expansion, announced Tuesday by Health Minister Uzoma Asagwara, means that more than 1,500 newborns in the province have been screened for cCMV since December 2025.
cCMV is a leading cause of non-genetic hearing loss in children, and can also result in cognitive impairment and developmental disabilities. Early detection is crucial, as infants with cCMV often reveal no symptoms at birth, potentially delaying diagnosis, and treatment. The addition of cCMV screening fulfills a promise made by the NDP government in its 2024-25 budget, aiming to provide earlier support for affected children and their families.
What is Congenital Cytomegalovirus?
Congenital cytomegalovirus (cCMV) is a viral infection passed from a mother to her baby during pregnancy. According to the Canadian CMV Foundation, approximately one in 200 Canadian infants contract the virus in utero. While many infected infants appear healthy at birth, about 20 percent will develop long-term health problems, including hearing loss, vision loss, and intellectual disabilities. The province’s existing newborn screening program already checks for over 40 rare disorders using a simple blood sample collected shortly after birth.
Rob Tétrault, chair and trustee of the Canadian CMV Foundation, has been a vocal advocate for universal cCMV screening in Manitoba for nearly two decades. His son, Alexandre, was born with cCMV, and early detection – through an ultrasound that flagged abnormalities – allowed for prompt treatment and minimized potential complications. “I can’t believe that it almost took 18 years to get here, but I’m very proud and thankful to the Manitoba government for putting this in finally,” Tétrault said.
The Importance of Early Detection
The lack of visible symptoms at birth is a key challenge in managing cCMV. Without screening, cases can move undetected, leading to delayed intervention and potentially more severe outcomes. Early identification allows healthcare providers to monitor infants closely and, when appropriate, initiate treatments like antiviral therapy, which can aid reduce the risk of long-term complications. The province’s expanded screening program aims to address this gap in care and ensure that all Manitoba families have access to the same preventative tools available elsewhere.
Premier Wab Kinew emphasized the government’s commitment to providing the best possible start for Manitoba’s children. “When a baby is born, families should know the health-care system is doing everything possible to give the child the strongest start,” Kinew stated in a government news release. “Universal cCMV screening means fewer families waiting for answers and more children getting the support they demand earlier. This is what investing in prevention looks like, real improvements that help Manitoba families from day one.”
As of now, the province does not have data on the number of infants detected with cCMV through the new screening program. A spokesperson for Minister Asagwara noted that accurate figures for annual cCMV diagnoses were unavailable, as routine screening only began in December 2025.
This expansion positions Manitoba as one of the first Canadian jurisdictions to implement universal cCMV screening, demonstrating a proactive approach to infant health and a commitment to early intervention. The long-term impact of this initiative will be closely monitored as more data becomes available.
The implementation of universal cCMV screening represents a significant advancement in preventative healthcare for newborns in Manitoba. As the program continues and more data is collected, it will be crucial to assess its effectiveness and identify any areas for improvement. Further research into cCMV and its long-term effects will also be essential to optimize care for affected children and families.
