Summary Summary


Listen
Chronic active Epstein-Barr virus infection (CAEBV) is a very rare complication of an Epstein Barr virus (EBV) infection. Symptoms of CAEBV may include fever, swollen lymph nodes, and an enlarged liver and/or spleen. More serious complications may include anemia, nerve damage, liver failure, and/or interstitial pneumonia. Symptoms may be constant or come and go, and tend to get worse over time. CAEBV occurs when the virus remains ‘active’ and the symptoms of an EBV infection do not go away. It is diagnosed based on the symptoms, clinical exam, and blood tests that show EBV DNA remaining at high levels for at least 3 months. Treatment is focused on managing the symptoms. The most well-documented, effective treatment for CAEBV is hematopoietic stem cell transplantation.[1][2][3]

Some people with fatigue alone are mistakenly thought to have CAEBV. Very specific testing looking for the level of EBV DNA is necessary to diagnose CAEBV.[3]

Symptoms Symptoms


Listen
The following list includes the most common signs and symptoms in people with chronic active Epstein-Barr virus infection (CAEBV). These features may be different from person to person. Some people may have more symptoms than others and symptoms can range from mild to severe. This list does not include every symptom or feature that has been described in this condition.[1][2][3]

Signs and symptoms include:
  • Fever
  • Swollen lymph nodes
  • Enlarged liver (hepatomegaly)
  • Enlarged spleen (splenomegaly)
  • Anemia 
  • Nerve damage
  • Liver failure
  • Pneumonia
About 95% of people become infected by Epstein-Barr virus (EBV) sometime in their life and most never have any health problems.[1] Some people with EBV will develop infectious mononucleosis or other illnesses, and will recover with no other problems.[4][5] Only rarely will an EBV infection develop into CAEBV. Over time, CAEBV can lead to failure of the immune system which, if not treated, can lead to potentially life-threatening complications.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause


Listen
Chronic active Epstein-Barr virus infection (CAEBV) is a rare complication of having Epstein-Barr virus (EBV). About 95% of people become infected with the EBV by adulthood and many will have no symptoms. CAEBV occurs when an EBV infection doesn't go away and the virus remains "active". This allows the symptoms of an EBV infection to persist and get worse over time.[1][3][4] It is not known why some people develop CAEBV and others do not.
Last updated: 11/2/2020

Diagnosis Diagnosis


Listen
Chronic active Epstein-Barr virus infection (CAEBV) is diagnosed based on the symptoms, a clinical exam and high EBV DNA in the blood which persists for at least 3 months. A test known as a quantitative PCR test is used to measure the amount of EBV DNA.[3]
Last updated: 11/2/2020

Treatment Treatment


Listen
Treatment for chronic active Epstein-Barr virus infection (CAEBV) includes medication to help manage the symptoms. Hematopoietic stem-cell transplant is currently the only curative treatment for this condition.[6]

Specialists involved in the care of someone with CAEBV may include:
  • Infectious disease specialist
  • Immunologist
  • Hematologist

Statistics Statistics


Listen
The exact number of people who have chronic active Epstein-Barr virus infection (CAEBV) is unknown. About 95% of people will become infected with the Epstein-Barr virus by adulthood.[1] Only a small number of these people will develop CAEBV.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.

Research Research
