ANS: Incidence Percentage of students enrolled in an epidemiology class who had sore throats on the first day of class. Ans: Prevalence Percent of breast cancer patients who underwent mastectomy during 2012. Ans: Cumulative Percent of men found to have high blood pressure at their yearly physical. Ans: Prevalence Number of newly-diagnosed cases of AIDS in a year per 100,000 persons. Ans:Incidence rate Percent of infants born with spina bifida out of 1,000 liveborn infants. Ans: LiveBirth rate Percent of drivers found to be legally drunk at the time of their car accident Ans:Incidence rate Suppose that you are following a group of children for the development of asthma over a one- year period. You identify 100 children on January 1st, screen them for asthma, and set up a monitoring program to check on their status on a monthly basis. Five children are considered prevalent cases because they were diagnosed with asthma before January 1st. Ten children develop asthma on March 1st and another ten children develop asthma on July 1st. Another 10 children who remain healthy were followed for six months and then were lost to follow-up. All of the remaining children did not develop asthma and were not lost to follow-up. Follow-up ended on December 31st. What was the prevalence of asthma on June 1st? 15/100=1.5% What was the prevalence of asthma on September 1st? 5+10+10/90=27.8% How many person-months of observation were accrued by this population? 12 months What was the incidence rate of asthma in this population for the one-year period? 20/90=22.2% An epidemiological investigation was begun on July 1, 2000 among a population of 1,000 individuals. Three individuals were found to have leukemia on July 1st. During the ten-year follow-up period, five new cases of leukemia were diagnosed. Among the eight leukemia cases, four deaths occurred during the ten-year follow-up period. Two additional individuals, neither of whom had leukemia, were lost to follow-up at some point during follow-up. None of the remaining 990 study participants became ill, died, or were lost to follow-up during the follow-up period. The diagram below indicates the experience of the 10 study participants, using the following symbols: * *
