Most people who are infected with non-polio enteroviruses do not get sick, or they only have mild illness. Symptoms of mild illness may include:

  • fever
  • runny nose, sneezing, cough
  • skin rash
  • mouth blisters
  • body and muscle aches

Some non-polio enterovirus infections can cause

  • viral conjunctivitis,
  • hand, foot, and mouth disease,
  • viral meningitis (infection of the covering of the spinal cord and/or brain)
  • viral encephalitis (infection of the brain)
  • myocarditis (infection of the heart)
  • pericarditis (infection of the sac around the heart)
  • acute flaccid paralysis
  • inflammatory muscle disease (slow, progressive muscle weakness)

People who develop myocarditis may have heart failure and require long term care. Some people who develop encephalitis or paralysis may not fully recover.

Newborns infected with non-polio enterovirus may develop sepsis (infection of the blood and other organs). But this is very rare.

Non-polio enterovirus infections may play a role in the development of type 1 diabetes in children.
