Homework Answers
1. The epidemic appear to be peak on 21st January ,1986
2. The highest number of cases reported during January 1986 is 96.
3. The total number of cases reported in January 1986 is 288.
4. The information that would be useful to characterize the epidemic are :-
- distribution
refers to the frequency and pattern of a health-related state or event
- frequency
the number of occurrences of a health-related state or event
-relation of that number to the size of the population (rate
- pattern
involves presenting the distribution by person, place and time characteristics
- determinants
collective or individual risk factor (or set of factors) that is causally related to a health condition, outcome, or other defined characteristic
-mat be physical stresses, chemicals, biological, social factors
- exposures
pertain either to contact with a disease-causing factor or to the amount of the factor that impinges upon a group of individuals

Later that afternoon, preliminary culture results from 17 ill students became available. The specimens, collected primarily from the emergency room at Hospital A on March 10, did not identify Salmonella, Shigella, Campylobacter, Vibrio, Listeria, Yersinia, Escherichia coli O157:H7, Bacillus cerns, or Staphylococcus aures. Some specimens were positive for fecal leukocytes and fecal occult blood. Question 6 How might you interpret the bacterial culture results? What questions do these results raiso?
