Vivian, a 37-year-old IT consultant, woke up early this morning with profuse vomiting, watery 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. In the ER, she was first seen by the triage nurse, who decided that she should be isolated with "enteric precautions" and noted she was febrile with a temperature of 38.6 C. She was subsequently seen by the ER physician who discovered the following: Vivian is an otherwise healthy woman, with no known medical problems and only takes a multivitamin daily. The day prior she had attended her 5 year old niece's birthday party. She cannot recall any sick contacts but is not sure if anyone else from the party has developed similar symptoms. Additionally, she recently returned from a trip to India 5 days prior. 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.
