incubation period --time between exposure to the microorganism and the onset of signs
or symptoms; it may last for a day or so or maybe prolonged props for days or weeks.
prodromal period --comprises the time in the early development of a disease when one
is aware of a change in the body, but the signs are non-specific. lab tests are negative.
manifestations of disease --clinical evidence or effects, the signs and symptoms, of
disease.
diagnosis --identification of a specific disease through evaluation of signs and
symptoms laboratory tests or other tools. More than one factor is usually required to
verify a diagnosis.
etiology --concerns the causative factors in a particular disease. there may be one or
several causative factors.
idiopathic --when the cause of a disease is unknown.
iatrogenic --a treatment, a procedure, or an error may cause a disease
Pathophysiology --the study of functional or physiologic changes in the body that result
from disease processes.
Pathology --the laboratory study of cell and tissue changes associated with disease.
Homeostasis --the maintenance of a relatively stable internal environment regardless of
external changes.
predisposing factors --Encompass the tendencies that promote development of a
disease in an individual.
prophylaxis --designed to preserve health (as of an individual or society) and prevent
the spread of disease. Prophylactic treatment for myocardial infarction for high-risk
patients is a baby aspirin daily.
prevention --closely linked to etiology and predisposing factors for a specific disease.
Preventive measures include vaccinations, dietary or lifestyle modifications, removal of
harmful materials in the environment, and cessation of potentially harmful activities such
as smoking.
pathogenesis --development of the disease or the sequence of events involved in the
tissue changes related to the specific disease process.
