An incidence rate measures the occurrence of new cases of disease in a population within a designated time frame. Group of answer choices True False An incidence rate of breast cancer in Lee County for the year 2020-2021 is an example of a measure of: Group of answer choices mortality morbidity attack rate prevalence

Calculating Incidence versus Prevalence The picture represents 10 new cases of illness over about 15 months in a population of 20 persons. Each horizontal line represents one person. The down arrow indicates the date of onset of illness. The solid line represents the duration of illness. The up arrow and the cross represent the date of recovery and date of death, respectively. The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the period prevalence from October 1, 2004, to September 30, 2005. The numerator of period prevalence includes anyone who was ill any time during the period. In Figure 3.1, the first 10 persons were all ill at some time during the period.

What patterns do you detect? Often in disease outbreak investigations we want to see a pattern for a particular problem. Think back to the 'white board' approach from a previous question and consider the types of information about individuals that may help you look for patterns.  Select from the list below attributes that may help you   You can chosse all or some I choose  Time of disease onset and occuption but there is more I guess              Occupation Hair color Gender Weight Age Time of disease onset

Questions 61 - 63 are based on the following information. The following equation is an epidemiological model for diseases such as measles or flu describing the factors that are expected to affect disease spread rate (R.) in a population: Ro = BS/y B = the infection rate (describes how infectious a disease is); y = the recovery rate (describes how fast can an infected person recover); S = Population density of susceptibles (suscptibles are individuals without immunity to the specific pathogen) 61. What type of a model is this? a. Verbal b. Mathematical C. Statistical d. Simulation 62. According to this model, what is the effect of Population density of susceptibles on disease spread rate? Disease spread rate increases with increasing density Disease spread rate decreases with increasing density Disease spread rate is not affected by increasing density Impossible to know а. b. c. d. 63. According to this model what is the effect of host recovery rate on disease spread rate? Disease…

Circle type of the study design below indicated. An investigator takes a sample of healthy individuals, record their ongoing solar exposure, and relate that to the subsequent occurrence of skin cancer in the same group. Case-control study Ecological study Cohort study Cross-sectional study

A study was conducted by the NIH (National Institute for Health) with a large population that examined smoking and the occurrence of lung cancer. In the duration of the study period, 1,800 smokers developed lung cancer. In the same period, 200 nonsmokers developed lung cancer. There were 241,800 current smokers and 478,000 nonsmokers in the total study population.   1.what type study ? Study design options: Ecological, Cross-sectional, Case Control, Prospective Cohort, RetrospectiveCohort, Randomized Clinical Trial

The picture New: Cases of Illness from October 1, 2004–September 30, 2005 Question: Calculate the incidence rate from October 1, 2004, to September 30, 2005, using the midpoint population (population alive on April 1, 2005) as the denominator. Express the rate per 100 population.
