spreading of herpangina HFM

A
PSA. I stay at home with my 13 month old son. However, last week we visited family via plane. We just got back from ped’s office. My son had/has mild hand foot and mouth disease and/or herpangina.   I want everyone to know my son did not have a scary looking rash or blisters. It was three red marks, one on face, buttcheek, and hand. The doctor found healing sores in his mouth. I now have a red sore on my throat 😣
In short, Please wash your hands and other items people touch.  If you are able, please keep your infected child at home.
