question 51

Essay

Suppose that you are the State Epidemiologist and you are notified about 10 cases of hemolytic uremic syndrome where the stool samples suggest the agent is either E. coli or salmonella. Describe the epidemiology of these diseases (E. coli and salmonella are associated with gastrointestinal diseases) include sources of bacteria, mode of transmission, portals of entry and exit. If during you investigation the laboratory analyses find all of the isolated to be E. coli but only two of the isolates to be genetically identical, would you consider this an outbreak? Explain you reasoning.
