Cytomegalovirus (CMV) (from cyto-'cell' via Greek κύτος kútos - 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, [3] in the subfamily Betaherpesvirinae. Humans and other primates serve as natural hosts.
A study published in 2009 links infection with CMV to high blood pressure in mice, and suggests that the result of CMV infection of blood vessel endothelium in humans is a major cause of atherosclerosis. [51] Researchers also found that when the cells were infected with CMV, they created renin, a protein known to contribute to high blood pressure.
The incidence of primary CMV infection in pregnant women in the United States varies from 1% to 3%. Healthy pregnant women are not at special risk for disease from CMV infection. When infected with CMV, most women have no symptoms and very few have a disease resembling infectious mononucleosis. It is their developing fetuses that may be at risk ...
Mammals serve as natural hosts. There are 26 species in this subfamily, divided among 5 genera. Diseases associated with this subfamily include: human cytomegalovirus (HHV-5): congenital CMV infection; HHV-6: 'sixth disease' (also known as roseola infantum or exanthem subitum); HHV-7: symptoms analogous to the 'sixth disease'.

Cytomegalovirus (a type of herpes virus) is what causes cytomegalovirus retinitis. Other types of herpes viruses include herpes simplex viruses and Epstein-Barr virus. Once an individual is infected with these viruses they stay in the body for life. [8] What triggers the virus to reactivate are the following (though CMV can also be congenital). [7]
The infection is spread by saliva, urine, respiratory droplets, sexual contact, and blood transfusions. Most people are exposed to the virus in their lifetime, but it usually produces mild or no symptoms in healthy people. [citation needed] However, serious CMV infections can occur in people with weakened immune systems.
