Cytomegalovirus (CMV) infection - including symptoms treatment and prevention
This infection is caused by cytomegalovirus (CMV). This virus occurs worldwide and humans are the only source of human CMV.
How Cytomegalovirus (CMV) is spread
CMV infection can spread in different ways. The virus can be passed from person-to-person, usually through close contact with saliva, breast milk, urine or other body fluid, or through sexual contact with someone with the infection.
A person can have a primary infection (an infection with CMV for the first time), or a return of a previous CMV infection (reactivation), or may have another infection with a different strain (type) of the virus.
CMV can also be transmitted during blood transfusions and organ transplants.
Babies can also become infected during delivery and from breast milk, but these babies have few, if any, symptoms or complications from the infection.
Women who become infected with CMV while pregnant may pass the virus to their unborn child (congenital CMV).
If an unborn baby is infected with CMV, some of these babies may develop serious health problems such as hearing loss, developmental delay or learning problems. Infection with CMV during pregnancy may also lead to stillbirth or infant death.
Congenital CMV is the most common infective cause of congenital hearing loss.
Signs and symptoms for CMV infection
Infection in children and adults is usually without symptoms.
Occasionally, symptoms similar to glandular fever such as fever, sore throat, swollen glands, abdomen pain and jaundice (yellow skin and eyes) can occur.
CMV infection can result in severe disease for:
people who receive solid organ transplants or bone marrow/stem cell transplants.
