cases every month. During the period between January 1 & April 1, 2005, 2,200
new cases of influenza occurred in the city. Of these cases, 775 persons were ill
with influenza according to surveillance reports on April 1, 2005. The prevalence

incidence rate of active cases of influenza for the 3-month period was: -
ANSWER: 20 per 1,000 population
What type of prevention is screening or exams? - ANSWER: Secondary
Prevention

rehabilitation program?

What prevention attempts to minimize negative effects, prevents further disease or
disorder related to complications, prevent relapse, and restore the highest physical
or psychological functioning possible? - ANSWER: Tertiary Prevention
The incidence & prevalence rates of a chronic childhood illness for a specific
community are given below. - ANSWER: The duration of disease is becoming
longer
The following table gives the mean annual age-specific mortality rates from
measles during the first 25 years of life in successive 5-year periods. You may
assume that the population is in a steady state (i.e., migrations out are equal to
migrations in). Based on the information above, one may conclude: - ANSWER:
Children ages 5 to 9 had the highest rate of death in all periods
. In a country with a population of 16 million people, 175,000 deaths occurred
during the year ending December 31, 2005. These included 45,000 deaths from
tuberculosis (TB) in 135,000 persons who were sick with TB. Assume that the
population remained constant throughout the year. Not all 135,000 cases of TB
were contracted during 2005. Which of the following statements is true? -
ANSWER: None of the above
In 2001, a state enacted a law that required the use of safety seats for all children
under 7 years of age & m&atory seatbelt use for all persons. The table above lists
the number of deaths due to motor vehicle accidents (MVAs) & the total
population by age in 2000 (before the law) & in 2005 (4 years after the law was
enacted). - ANSWER: Correct, because both the total & the age-adjusted mortality
rates are higher in 2005 than in 2000
Which of the following is an advantage of active surveillance? - ANSWER: More
accurate due to reduced reporting burden for health care providers

A disease has an incidence of 10 per 1,000 persons per year, & 80% of those
affected will die within 1 year. Prior to the year 2000, only 50% of cases of the
disease were detected by physician diagnosis prior to death. In the year 2000, a lab
test was developed that identified 90% of cases an average of 6 months prior to
symptom onset; however, the prognosis did not improve after diagnosis. Which
statement is true concerning the duration of the disease after the development of
the lab test? - ANSWER: Mean duration of a case of the disease is longer in 2000
What is the overall attack rate in persons who did not eat ice cream? - ANSWER:
33%
The table above describes the number of illnesses & deaths caused by plague in
four communities. The proportionate mortality ratio associated with plague is
lowest in which community? - ANSWER: Community D
Which of the following is characteristic of a single-exposure, common-vehicle
outbreak? - ANSWER: The epidemic curve has a normal distribution when plotted
against the logarithm of time
The following table gives the mean annual age-specific mortality rates from
measles during the first 25 years of life in successive 5-year periods. You may
assume that the population is in a steady state (i.e., migrations out are equal to
migrations in). - ANSWER: 2.4 3.3 2.0 0.6 0.1
