This essay focus on Infectious and Communicable Diseases.Describe how the concept of multifactorial etiology relates to the natural history of disease and the different levels of prevention.

 Infectious and Communicable Diseases

Topic 1: Disease Outbreak
Select an infectious disease and research the CDC website for information about the disease including:
Firstly, its natural history,
Secondly, presenting symptoms, and
Further,  outbreak characteristics
Finally, Identify an occurrence of the disease by searching the Internet for recent reports of this disease and compare that episode or occurrence with information from the CDC website.
Firstly, how closely did that outbreak resemble the case definition?
Topic 2: Epidemiological Applications
Secondly, describe how the concept of multifactorial etiology relates to the natural history of disease and the different levels of prevention.
Thirdly, how should the nurse incorporate these concepts into health promotion of clients in community settings?
Lastly, how should the nurse approach client risk in these health promotion activities?

A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.

Reporting of cases of communicable disease is important in the planning and evaluation of disease prevention and control programs, in the assurance of appropriate medical therapy, and in the detection of common-source outbreaks. California law mandates healthcare providers and laboratories to report over 80 diseases or conditions to their local health department. Some examples of the reportable communicable diseases include Hepatitis A, B & C, influenza, measles, and salmonella and other food borne illnesses.

How do these communicable diseases spread?

How these diseases spread depends on the specific disease or infectious agent. Some ways in which communicable diseases spread are by:

1. Further, bites from insects or animals capable of transmitting the disease (mosquito: malaria and yellow fever; flea: plague); and
2. finally, travel through the air, such as tuberculosis or measles.
