What Is CMV?

CMV, or cytomegalovirus, is a common virus that belongs to the herpesvirus family. It is often referred to as a silent infection because many people who have it show no symptoms. In fact, most adults have been infected with CMV at some point in their lives, but they may not even realize it. The virus can remain dormant in the body and can reactivate later, especially in individuals with weakened immune systems.

How Is CMV Transmitted?

CMV is primarily spread through direct contact with bodily fluids, including:

• Saliva
• Urine
• Blood
• Semen
• Breast milk

It can be transmitted through kissing, sexual contact, organ transplantation, and from mother to child during pregnancy or childbirth. This makes understanding CMV particularly important for pregnant women, as it can lead to serious health issues for the baby.

Who Is at Risk?

While CMV can affect anyone, certain groups are at higher risk of complications:

• Pregnant women
• Newborns
• Individuals with weakened immune systems (e.g., those with HIV/AIDS, organ transplant recipients)
• Individuals undergoing chemotherapy

For these populations, CMV can lead to severe health issues, including CMV retinitis, which can cause vision loss, and other systemic infections.

CMV Symptoms

Most people with CMV do not experience any symptoms. However, when symptoms do occur, they can resemble those of other viral infections. Common symptoms of a CMV infection may include:

• Fever
• Fatigue
• Sore throat
• Swollen glands
• Muscle aches

These symptoms can last for several weeks and may be mistaken for other illnesses, such as mononucleosis. In individuals with weakened immune systems, symptoms can be more severe and may include:

• Pneumonia
• Gastrointestinal issues
• Neurological problems

CMV in Pregnancy

For pregnant women, CMV poses a unique risk. If a mother contracts the virus during pregnancy, it can be transmitted to the fetus, potentially leading to congenital CMV infection. This can result in serious complications, including:

• Hearing loss
• Vision problems
• Developmental delays

It’s crucial for pregnant women to be aware of CMV and take preventive measures, such as practicing good hygiene and avoiding contact with bodily fluids from young children, who are often the source of the virus.

When to Seek Medical Attention

If you suspect you have been exposed to CMV or are experiencing symptoms, especially if you are pregnant or have a weakened immune system, it is important to consult a healthcare professional. They may recommend a CMV test to determine if you have an active infection.
