Or are you saying they are home sick and you are traveling? And if it is just you and you have a sick kid and a temp, then there is a good chance you are sick and spreading it to all you come in contact with.

Here in the DFW area my 2 kids got the flu in December and the school would not allow them back to school until they had no fever for 48 hours with no medicine.

And here in TX they take attendance very seriously unlike Utah.
