Reference no: EM133563885

An older Hispanic man arrives at the emergency room complaining of 2 days of severe abdominal pain, fever, and headache. He is also experiencing diarrhea, however there is no blood or mucus in his stool. His nephew tells the ER attendant that his uncle has only been in the US for 3 days and recently arrived from his small village in rural India, which is still without power or water from recent typhoons. Stool samples indicated the presence of a Gram negative, rod-shaped, motile bacterium. Further testing was done to narrow down the cause of his illness. The man was given IV fluids to rehydrate and a round of antibiotics to clear the infection. Within a few days, his symptoms were much improved and by the end of the round of antibiotics, he had fully recovered..
