Return of the Whoop
This week we will examine a case study that outlines the history of pertussis, or whooping cough. In the 1930s Pearl Kendrick and Grace Eldering developed a vaccine that by the 1960s reduced the rate of incidence to 5% of what it was in 1934. But the disease was not eradicated, and by 2013 the number of cases was triple the number of the 1980s. Why the resurgence? Use the case study attached and the internet to answer the questions below.
Read through the attached case study and answer any 2 questions from part II, and any 2 questions from part III. (*note: this is different from previous discussion weeks). You will still be answering 4 questions total. Make sure you include the parts and question numbers in your post so we know which 4 questions you are answering.
