For any public health official, this is a frustrating example of what happens when people don't heed the advice of a doctor. When the presidential candidate was first diagnosed, she should have rested, stayed hydrated, and followed her doctor's advice in terms of medication. It was standard protocol. But she didn't heed the advice. Instead, she kept on with her campaign thinking it was no big deal. She felt she could push through the pneumonia. She learned the consequences the hard way.
