1) a. What is a common symptom of E. coli that generally resolves in 5 to 10 days?

          b. What is one of the most serious complications of infection with E. coli 0157:H7?

      2) a. How is the infection confirmed? 

          b. Is it done routinely?

      3) a. When was E. coli 0157:H7 added to the list of notifiable diseases?

      b. How much time do physicians and clinical laboratories have to report the infection to the local health department?  Not in PDF. 

3 days

      4) a. How is the diagnosis confirmed (where is it sent)? State lab or CDC

          b. What test is performed to see if the cases are related?

      5) What were the results of that test in this study?

      6) What were the case definitions developed (clinical criteria and restrictions)?

      7) a. What was the date of the largest number of new cases?

          b. Because of the shape of the curve, did they think it was from a point source or a continuous common source? 

The PDF only states that it was from a common source but does not specify “point” vs “continuous common”. You will have to compare the graph in the PDF with the CDC descriptions in the below sites.

      8) From the interviews, what were first possible sources of the infection considered?

      9) a. What did they determine was the most likely source of most of the cases?

          b. What did they determine was the likely source of infection of the children who did not eat the source food?

      10) What was determined to be the most likely source of the E. coli (in other words, how did the food that everyone ate itself get contaminated)?
