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:

• Acute gastroenteritis
• Viral pharyngitis
• Herpangina (mouth sores)
• Croup
• Upper respiratory infection
• Pneumonia
• Pericarditis
• Myocarditis
• Aseptic meningitis
• Encephalitis

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.

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.
