12. For US Residents, Excluding US Territories:
    1. Record the “Current Week” number of cases for the given week
    2. Record the Cumulative Year to date (YTD) number of cases for 2019 on the associated table (for the given week).
    3. Record the Cumulative Year to date (YTD) number of cases for 2018 on the associated table (for the given week).
13. Go back one web page
14. Repeat steps 7 through 12 for Week 2
15. Continue repeating steps 7-15 for all 52 weeks
16. Graph the weekly number of cases for all 52 weeks in 2019.
17. Calculate the difference between the number of weekly cases from 2018 and 2019. Record on the associated data sheet.
18. Calculate the number of new cases during each 4-week period (weeks 1-4, weeks 5-8, ect.). Record that data on the associated data sheet.
19. Calculate the incidence values of each 4-week period during the entire year using the calculated 4-week totals in the numerator of the following formula and using 327,000,000 (approximate size of US population in 2019) in the denominator of the formula. Record that data on the associated data sheet.
    1. Incidence Rate = (Number of New Cases / Size of At-Risk Population) X 10⁸
20. Answer the following questions and submit with the data sheet as the total written assignment. It is due December 1, 2020.
    1. Describe the disease that you have chosen. Be sure to include the etiological agent (scientific name), symptoms, modes of transmission, diagnostic tests, and treatments.
