ER and bacterial infection

Julie took Elena to the Children's Hospital at 2am when she spiked a high fever, was breathing quickly, and showed signs of hallucinating. We thought the cause might be food poisoning because Ethan threw up during the same hour, but it appears that was unrelated. After x-rays and bloodwork the current diagnosis is a bacterial infection. Her fever is down now, but the potential CF lung infection is weighing heavy on our hearts. Not sure how long she'll be in hospital. Prayers appreciated.
