What is the causative agent of the disease? Is it a bacterium, a virus, a prion,or a eukaryote? Describe in detail its characteristics.
a. If it is a bacterium, what are the characteristics of the cell (Gram-reaction? cell
shape and arrangement? metabolic capabilities?).
b. If it is a virus, what are its characteristics (DNA, positive-strand RNA,
negative-strand RNA, or retrovirus? enveloped or naked? how large is it?
3 of 4 does it form a provirus? Any unique characteristics of its multiplication
cycle?).
c. If it is a prion, what is a prion? Wherein the body does it occur? What is the
function of the normal-type protein?
d. If it is eukaryote, is it a fungus, an alga, a protozoan, a platyhelminth, or a
nematode? Is it multicellular or unicellular? What is its life cycle?
B. History: How long have we known about this disease?
a. Describe the changes in our knowledge and attitudes toward this disease
throughout history.
C. Epidemiology: Describe the prevalence and transmission of this disease.
a. Where (in the world) is the disease prevalent? How many people are currently
infected? What is the rate of new infections? What are the rates of morbidity
and mortality?
b. What is (are) the reservoir(s) of the pathogen? What is (are) the mode(s) of
transmission?
D. Pathology: Describe the pathogenic effects on cells, tissues, and organ
systems.
a. Where in the body (what tissues/organs/cells) does the pathogen affect?
b. What damage does the pathogen inflict? How is this damage inflicted (is there
direct mechanical damage? is a toxin produced? does the immune response
cause damage?)?
c. What is the time sequence of the disease (length of incubation, prodrome,
illness, decline, and convalescence)? Are there sequalae?
d. What are the major signs and symptoms?
E. Response and Treatment
a. Describe the activity of our immune system against the pathogen.
b. What types of medical treatments exist? Describe how these treatments
affect the progression of the disease.
c. Describe prophylactic measures that can be taken to limit the risk of infection.
F. Socio-politico-economic
a. Describe any historic or present day social, economic, or political issues that
either help or hinder us in limiting the spread of the disease.
