Addie went to bed feeling a bit tired but woke up the next morning feeling very sick. She was transported to the hospital that day. What could be a reason for this sudden change in her health?
Bacteria can reproduce every 20 minutes so the bacterial population grew exponentially.
She was dehydrated which caused a spike in fever.
