QUESTION 34 What was the cumulative incidence of TB over the year? (a)/(b)=(c) Formatting you answer: DO NOT enter ANYTHING except the final numbers you arrive to for your numerators, denominators, and percent answer. This means I do not need to see your numerator math, for example, your conversion from decimal to percent, or any parentheses. This question auto-grades based on the expected format of your answer. numerator=a denominator=b percentage=c (To one decimal point) QUESTION 35 What was the case-fatality rate among residents with TB over the course of the year? (a)/(b)/=(c) Formatting you answer: DO NOT enter ANYTHING except the final numbers you arrive to for your numerators, denominators, and percent answer. This means I do not need to see your numerator math, for example, your conversion from decimal to percent, or any parentheses. This question auto-grades based on the expected format of your answer. numerator=a denominator=b percentage=cQuestions 32 through 35 use the following scenario: Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 131, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 151, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 131, On February 131, two residents developed TB. On April 12, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 12 died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up. What was the prevalence of TB in the screened community on January 1st?
