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

Less commonly, a person may develop:

  • myocarditis (infection of the heart)
  • pericarditis (infection of the sac around the heart)
  • encephalitis (infection of the brain)
  • paralysis

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.
