Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.

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
Please help Do the positive effects of this law outweigh the negative effects? Make a list of pros and cons to compare. Just Q&A not writing assignment.
Hi. Please answer this question Thanks
The causality component "association specificity" applies only to chronic diseases. false True The causality component "response dose" is met when a genetic factor is being evaluated. false True The inconsistency and discrepancy of the results in studios that evaluate the same association do not represent a causal component. False True In the case of Hepatitis B, the causal elements are needed: "enough and necessary" False True
