People with CMV may pass the virus in body fluids, such as saliva, urine, blood, tears, semen, and breast milk. CMV is spread from an infected person in the following ways: From direct contact with saliva or urine, especially from babies and young children. Through sexual contact.

Over and above that, how does a woman get CMV?
CMV spreads in several ways: Passing it to your baby during pregnancy, labor, birth, or nursing. Touching your eyes or the inside of your mouth or nose after direct contact with an infected person's body fluids, including saliva, urine, blood, tears, semen and human milk.
Above, how is CMV activated? CMV may cycle through periods when it lies dormant and then reactivates. If you're healthy, CMV mainly stays dormant. When the virus is active in your body, you can pass the virus to other people. The virus is spread through body fluids — including blood, urine, saliva, breast milk, tears, semen and vaginal fluids.
In any manner, can you get rid of CMV?
There's no cure for CMV. The virus stays inactive in your body and can cause more problems later. This reactivation is most common in people who've had stem cell and organ transplants.
Who is most affected by CMV?
People who have frequent contact with young children may be at greater risk of CMV infection because young children are a common source of CMV. By the age of five years, one in three children has been infected with CMV, but usually does not have symptoms.

The majority of children born who experience a CMV infection before birth are healthy and normal. However, 10 to 15% may have complications such as hearing loss, neurological abnormalities, or decreased motor skills. Infants who are infected with CMV after they are born rarely experience any long-term complications.
CMV can be sexually transmitted. It can also be transmitted via breast milk, transplanted organs and, rarely, blood transfusions. Although the virus is not highly contagious, it has been shown to spread in households and among young children in day care centers.
Testing for CMV infection is a simple blood test
, called a CMV IgG antibody. It will determine if a pregnant woman
has had CMV. A positive result indicates a current or past CMV infection. A second blood test, called CMV IgM antibody will help determine if the CMV infection is current or past.
CMV is spread from one person to another, usually by direct and prolonged contact with bodily fluids, including saliva, urine, and breast milk. CMV is common among healthy children one to three years of age who attend daycare and can easily spread the CMV virus among their peers.
The reactivation of CMV occurs in 30% of immunocompetent patients with acute respiratory distress syndrome (ARDS) and is associated with increased mortality. CMV reactivation is especially concerning in patients with COVID-19 because ARDS is a common complication of severe COVID-19.
Estimated reactivation rates increase from low values in children to 2%-4% per year in women older than 50 years. The results advance a hypothesis in which transmission from adults after infectious reactivation is a key driver of transmission.
When the host is infected, CMV DNA can be detected with polymerase chain reaction (PCR) in all the different cell lineages and organ systems in the body. Upon initial infection, CMV infects the epithelial cells of the salivary gland, resulting in a persistent infection and viral shedding.
CMV infection is permanent Once a person has contracted CMV, they will carry it for life. This is because the virus lies dormant inside the body and may or may not reactivate itself at any time.
Most healthy individuals who have a CMV infection will not have symptoms. However, when symptoms are present, they are often similar to those of glandular fever. Severity and duration can vary but, on average, will last for two to three weeks.
If untreated, it can spread throughout the body, infecting organ after organ. It may cause respiratory problems, damage to the central nervous system, bleeding ulcers in the digestive system, and CMV retinitis, which can lead to blindness.
CMV is dispersed and becomes dormant in multiple end organs, a state also referred to as "latency," and can later be reactivated by a number of different stimuli, including immunosuppression and inflammation (reviewed in ).
How is CMV spread? Although the virus is not highly communicable, it can be spread from person to person by direct contact. The virus is shed in the urine, saliva, semen and to a lesser extent in other body fluids.
The enzyme-linked immunosorbent assay (ELISA) is the most common serologic test for measuring antibody to CMV. A positive test for CMV IgG indicates that a person was infected with CMV at some time during their life but does not indicate when a person was infected.
The age-adjusted years of potential life lost for all congenital CMV deaths was 56,355 years. The infant mortality rate associated with congenital CMV was 8.34 per 1 million infants annually (95% CI, 7.65–9.04).
Antibodies are germ-fighting molecules that your immune system makes in response to infection. If you have CMV-specific antibodies in your blood, you may have a CMV infection. Like other herpes family viruses, CMV hides in the body after the first infection and can flare up again. Later infections tend to be milder.
CMV has been associated with impaired immunity, increased morbidity due to cardiovascular diseases, and reduced lifespan and health span – the length of life spent in good health.
Cytomegalovirus infection is a common herpesvirus infection with a wide range of symptoms: from no symptoms to fever and fatigue (resembling infectious mononucleosis) to severe symptoms involving the eyes, brain, or other internal organs.
Person-to-person contact - CMV is spread from one person to another by close and prolonged contact with bodily fluids such as urine, saliva, blood, faeces, tears, breast milk, semen and cervical secretions. You can catch CMV by kissing, sexual intercourse, sharing eating and drinking utensils, and sharing mouthed toys.
Cytomegalovirus (CMV) is a virus related to the herpes virus. It is so common that almost all adults in developing countries and 50% to 85% of adults in the United States have been infected. Usually CMV is a mild disease that does not cause any serious problems in healthy children and adults.
The CMV blood test is performed to detect current active CMV infection, or past CMV infection in people who are at risk for reactivation of infection. These people include organ transplant recipients and those with a suppressed immune system. The test may also be performed to detect CMV infection in newborns .
The drug of choice for treatment of CMV disease is intravenous ganciclovir, although valganciclovir may be used for nonsevere CMV treatment in selected cases. Ganciclovir is a nucleoside analogue that inhibits DNA synthesis in the same manner as acyclovir.
Around 1 in 150 newborn babies are born with congenital CMV. The majority of these will not have any symptoms. However, around 1 in 1,000 babies born in the UK every year will have permanent disabilities as a result of CMV. This is around 2 to 3 babies born every day in the UK.
Primary CMV infection will cause up to 7 percent of cases of mononucleosis syndrome and will manifest symptoms almost indistinguishable from those of Epstein-Barr virus-induced mononucleosis. CMV, or heterophil-negative mononucleosis, is best diagnosed using a positive IgM serology.
Liver damage is a characteristic feature of the clinical syndromes caused by cyto- megalovirus (CMV) infection in man. Jaundice and hepatosplenomegaly occur commonly in cytomegalic inclusion dis- ease of the newborn.
Although it's common, CMV is hard to catch. Spread through bodily fluids like urine, saliva, tears, semen, breast milk, mucus, and blood, CMV isn't airborne or considered to be highly contagious. “You don't get CMV from casual contact like riding the bus; it's from exchanging body fluids at an intimate level,” Dr.
The human cytomegalovirus structure consists of an outer lipid bilayer envelope, composed of various viral glycoproteins, followed by the tegument, a proteinaceous matrix, which holds double stranded linear DNA core in an icosahedral nucleocapsid. The virion is usually spherical in composition .
Abstract. Cytomegalovirus (CMV) is generally described as a slowly replicating virus. During studies of immunocompromised patients, we observed rapid changes in the quantity of CMV DNA present in serial blood samples by quantitative-competitive polymerase chain reaction commensurate with a doubling time of <2 d.
