How do I prevent CMV infection?

CMV is easy to pass from one person to another. You may already have it, and your doctor can test for CMV infection. Uninfected people can take steps to lower their risk of infection.

If you are not already infected with CMV, washing your hands often and well and using condoms during sex may help prevent CMV infection. If you expect to get a blood transfusion or organ transplant, talk to your doctor about what can be done to lower your risk of infection. When possible, uninfected people should be given blood products and organs that are free of the virus.

CMV is common in young children so being careful around them will help prevent infection. Some suggestions include washing your hands after contact with children; after contact with their saliva, tears or urine; or after contact with objects that they’ve touched such as cups, pacifiers, utensils, toys and diapers. Refraining from touching your eyes, nose and mouth in these situations is important, as well as not sharing food or drinks with them. These activities may be nearly impossible to avoid while parenting, in households with children, day care centers and schools.
