Understanding CMV – Information for Patients and their Loved Ones

Cytomegalovirus (CMV) is a common virus that affects people of all ages. More than half of all adults in the United States have been infected with CMV by the age of 40. While most healthy people experience little to no symptoms, CMV can cause serious health complications for some.

What is CMV?

CMV is a member of the herpes family of viruses and it can be transmitted in a number of ways, including through sexual contact, blood transfusions, and organ transplants. It can also be passed from a pregnant woman to her fetus.

In most cases, CMV infection causes no symptoms or only mild symptoms that may resemble those of the flu. However, in people with weakened immune systems or in babies infected with CMV before birth, the virus can cause serious complications.

Symptoms of CMV

For most people, CMV infection causes no symptoms or only mild symptoms such as fever, tiredness, and muscle aches. However, in people with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, CMV can cause serious health complications such as pneumonia, encephalitis, and retinitis.

In babies infected with CMV before birth, the virus can cause a number of health problems including hearing loss, microcephaly, and developmental delays.

Diagnosis and Treatment

CMV infection is typically diagnosed through blood tests or urine tests. Treatment options vary depending on the severity of the infection and may include antiviral medications. However, for most healthy people, no treatment is necessary as the virus will clear up on its own.

For pregnant women, early detection of CMV infection is important as it allows for timely medical intervention that can help prevent or minimize the risk of transmission to the fetus. Women who are planning to become pregnant or who are pregnant should talk to their healthcare provider about CMV testing.

Prevention

There is no vaccine for CMV, but there are steps that can be taken to help prevent the spread of the virus. These include practicing good hygiene, such as washing your hands frequently, avoiding close contact with people who are sick, and using protection during sexual activity. If you work in a healthcare setting, follow standard precautions to prevent the spread of infections.

Conclusion

CMV is a common virus that can cause serious health complications for some, particularly those with weakened immune systems or infants infected before birth. While there is no cure for CMV, early detection and medical intervention can help prevent or minimize the risk of complications. Practicing good hygiene and taking precautions during sexual activity can also help prevent the spread of the virus. If you are concerned about CMV or have questions about testing, speak with your healthcare provider.
