So sorry to hear about your granddaughter. They are probably giving her steroids for her asthma. (I've been through this with my daughter many times.) I don't mean to scare you, but I feel that I should share that with you.
I have recently been researching parasites, specifically strongyloides. There are several case studies where strongyloides was undetected and when treated with steroids, the patient's condition rapidly became life-threatening. The television show "Monsters Inside Me" had an episode about a case where that happened.
