ECHO virus

Definition

Enteric cytopathic human orphan (ECHO) viruses are a group of enteroviruses that produce varying symptoms including rashes, respiratory illness, croup-like syndromes, and nonspecific fevers.

Alternative Names

Nonpolio enterovirus infection

Causes, incidence, and risk factors

ECHO virus infections are common and usually take the form of gastrointestinal infection and skin rashes.

More serious infections are seen less frequently but are of significant importance. As many as one out of five cases of aseptic meningitis (a brain infection not caused by bacteria) is thought to be caused by an ECHO virus.

Symptoms

ECHO viruses cause a wide variety of conditions. Symptoms vary with the type of disease produced and can be found under the specific diagnosis:

Signs and tests

ECHO virus can be identified from throat, stool, and rectal swabs or from spinal fluid.

Treatment

ECHO virus infections tend to clear up on their own. No specific antiviral medications are available.

An immune booster called IVIG may help immunocompromised patients with severe ECHO virus infections.

Expectations (prognosis)

Complete recovery without treatment is expected in patients who have the less severe types of illness. Infections of organs such as the heart (pericarditis and myocarditis) may cause severe disease and can be fatal.

Complications

Complications vary with the site and type of infection. Myocarditis and pericarditis may be fatal while other types of infection improve on their own.

Calling your health care provider

Call your health care provider if you have symptoms suggestive of any of the diseases listed above.

Prevention

No specific preventive measures are available for ECHO virus infections other than hand-washing, especially when in contact with sick people. Currently, no vaccines are available.
