The risk for transmission of congenital cytomegalovirus (cCMV), a common in-utero infection and a leading cause of childhood hearing loss, in healthcare settings, daycare and schools including for pregnant workers is low. In fact, healthcare workers, regardless of the type of patient contact, do not have an increased risk of developing CMV infection when compared with the general population.12-16 The annual seroconversion rate for primary infection among healthcare providers was 2.3% compared with 2.1% among pregnant women in the community.12,17 Adults are at a much higher risk of acquiring CMV from children living in the same household than from an occupational exposure.18
Members of the Joint OHA/OMA Communicable disease Surveillance Protocols Committee published a cytomegalovirus surveillance protocol for all Ontario Hospitals in 2017.18 They concluded that CMV is not an occupational health and safety risk even for pregnant women if routine practices are followed. Routine practices include careful hand hygiene after all patient and patient environment contact, and the wearing of gloves if healthcare workers expect to contact body secretions or mucous membranes. They also recommend avoidance of kissing or cuddling infants and young children and not sharing utensils which risk bringing secretions from mucous membranes of the ears, eye, nose and mouth into close proximity of the worker. The National Institute for Occupational Safety and Health of the Centers for Disease Control and Prevention (CDC) website published similar recommendations for Healthcare workers, and childcare workers and teachers, regarding CMV and other infectious agents.19 The CDC’s 2007 Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings includes hand hygiene and personal protective equipment (gloves). Since not all children undergo CMV testing and most with CMV show no signs of this infection, workers and staff must follow these precautions for all children. These precautions should also apply to daycare workers or staff who work in schools and who are in contact with young children.
