Nonpolio enterovirus infection; Echovirus infection DefinitionEnteric cytopathic human orphan (ECHO) viruses are a group of viruses that can lead to infections in different parts of the body, and skin rashes. CausesEchovirus is one of several families of viruses that affect the gastrointestinal tract. Together, these are called enteroviruses. These infections are common. In the United States, they are most common in the summer and fall. You can catch the virus if you come into contact with stool contaminated by the virus, and possibly by breathing in air particles from an infected person. Serious infections with ECHO viruses are much less common but can be significant. For example, some cases of viral meningitis (inflammation of the tissue that surrounds the brain and spinal cord) are caused by an ECHO virus. SymptomsSymptoms depend on the site of infection and may include:
Exams and TestsBecause the illness is often mild and has no specific treatment, testing for echovirus is often not done. If needed, ECHO virus can be identified from:
TreatmentECHO virus infections almost always clear up on their own. No specific medicines are available to fight the virus. Immune system treatment called IVIG may help people with severe ECHO virus infections who have a weakened immune system. Antibiotics are not effective against this virus, or any other virus. Outlook (Prognosis)People who have the less severe types of illness should recover completely without treatment. Infections of organs such as the heart may cause severe disease and can be deadly. Possible ComplicationsComplications vary with the site and type of infection. Heart infections may be deadly, while most other types of infection improve on their own. When to Contact a Medical ProfessionalContact your health care provider if you have any of the symptoms listed above. PreventionNo specific preventive measures are available for ECHO virus infections other than hand-washing, especially when you are in contact with sick people. Currently, no vaccines are available.
