A healthy six-month old Infant was visiting her grandparents in late 2010. Upon returning home, she developed a slight dry cough and runny nose. Her mother thought it was a common cold and chose not to seek medical attention for the baby. By the end of the week, however, she and her husband knew this was not just a cold. Their daughter began to cough with such force that her face turned red, and she began to expectorate thick phlegm. At times, she even vomited. With each day, she became increasingly fatigued as well. Her mother finally brought her to the emergency room when her face turned blue during a bout of violent coughing. The following are the answers the parents provided for the patient history questionnaire: Question: What have been the patient's symptoms?

Question: When did the patient being to exhibit symptoms?

Question: Has the patient traveled recently?

Question: Has anyone else in the family traveled recently?

Question: Has the patient experienced any other recent illness?

Question: Is the patient up to date with vaccinations for her age (6 months)?
