Assignment

A population of 11,000 men was examined in January 2014. Of these men, 7,000 were exposed to high levels of air pollution, and 4,000 were exposed to low levels of air pollution. At the physical examination, 100 cases of chronic bronchitis were identified, including 70 cases among the high-exposure group. All of the men who were initially examined and did not have chronic bronchitis were followed by repeat examination over the next five years. These follow-up exams identified 329 new cases of bronchitis in the total group, including 52 cases among the low-exposure group. Calculate the prevalence and the incidence.
