AFM can be caused by viruses, including enteroviruses. Enteroviruses are common and usually cause mild illness. We are working to learn why a small number of people develop AFM after having a virus.

Since we don’t know what triggers AFM in a person, there is no specific action to take to prevent AFM. But you can take steps to prevent getting sick from a virus.

You can do a lot to lower your and your child’s risk of getting a virus:

You can lower the chance of spreading a virus:

  • Clean and disinfect frequently touched surfaces, like toys, mobile devices, and doorknobs.
  • Cover coughs and sneezes with a tissue or upper shirt sleeve, not hands.
  • Stay at home if you or your child are sick.
