Alternative Names:

Cytomegalovirus esophagitis

Causes, incidence, and risk factors:

CMV is caused by the cytomegalovirus (CMV). This condition usually affects people who have a weakened immune system.


Symptoms include:

  • Difficult and painful swallowing
  • Low-grade fever
  • Mouth sores (oral lesions)

Signs and tests:


Treatment involves antiviral medications that are given through a vein (intravenous) or by mouth (orally).

Support Groups:

Expectations (prognosis):

Esophagitis can usually be treated effectively. The outcome depends upon the immune system problem that makes the person susceptible to the infection.

  • Infection at other sites
  • Recurrent infection

Calling your health care provider:

Call your health care provider if you develop symptoms of CMV esophagitis, especially if you have a suppressed immune system.


Preventing AIDS can help avoid opportunistic infections, such as those caused by the cytomegalovirus. (Opportunistic infections are infections by organisms that are not normally disease-producing, but that take advantage of a situation, such as a damaged immune system.) People with AIDS who are effectively treated with antiretroviral therapy are much less likely to get CMV infection.
