Vivian Patel is a 35-year-old computer programmer who presents to the ER with a 10- hour history of profuse vomiting, watery non-bloody diarrhea and abdominal cramps. She first tried to fight this illness on her own by drinking water, however her symptoms were persistent and her husband brought her to the emergency room. She was first seen by the triage nurse, who noted that she was febrile with a temperature of 38.6 C. Given her presentation, the nurse decided that she should be isolated with "enteric precautions” and she was subsequently seen by the ER physician. Vivian is an otherwise healthy woman with no known medical problems and only takes a multivitamin daily. The day prior to her presentation with these symptoms, she had attended her 5-year-old niece's birthday party. She cannot recall any sick contacts, although is unsure if anyone else from the party has developed similar symptoms. Additionally, she had recently returned from a trip to India 5 days ago. She went on a business trip for a week and stayed to travel the country for another 3 thereafter. She did not receive any pre-travel advice or prophylaxis.
