Cytomegalovirus (CMV)

Cytomegalovirus (CMV) is a virus belonging to the Herpes-Virus family.

In an infected organism it can be found in urine, sexual secretions (sperm and vaginal secretions), saliva, sputum, breast milk and blood as well as affected organs.

The term cytomegalovirus is used because the virus causes the increase in lymphocyte size (blood cells) sign characteristic of a CMV infection.

Transmission mode

Transmission occurs through direct cutaneous or mucous contact (urine, saliva, breast milk, vaginal secretions, sperm), or during pregnancy from mother to fetus, or during blood transfusions or organ transplants.

The children carrying the germ are very numerous.

People at risk

Nursing staff and nursery staff may be in contact with carriers of CMV, precautions to avoid transmitting the virus are important to know.
