Most healthy adults experience few or no symptoms of cytomegalovirus infection, but if they do, they experience muscle aches, fatigue and fever, according to Mayo Clinic. Babies and adults with compromised immune systems report more serious symptoms, including seizures and pneumonia.
Individuals with compromised immune systems usually experience fatigue, muscle aches and fever, but they may also develop more serious symptoms from CMV, Mayo Clinic states. In this population, CMV may also attack specific organs.
Symptoms in the immuno-compromised include diarrhea, bleeding ulcers in the digestive tract, visual impairment, hepatitis and behavioral changes, as Mayo Clinic informs. They may also develop pneumonia, seizures and brain inflammation. In some cases, patients can experience coma and even death.
Patients with compromised immune systems should seek medical conditions if they have muscle aches, fever and fatigue, Mayo Clinic advises. Organ and bone marrow transplant patients tend to be at greater risk of contracting CMV.
Babies contract CMV at birth or through breastfeeding, Mayo Clinic explains. Mothers pass the virus on to their fetuses usually in the first trimester of pregnancy. Often, newborns with CMV appear healthy, sometimes for months or years.
When babies do have CMV symptoms at birth, they tend to be very ill, Mayo Clinic states. Signs include low birth weight, jaundice, an enlarged liver and spleen, and poor liver function. CMV also causes seizures, pneumonia, rashes and purple skin blotches.
