Bio 260 Epidemiology
1. Pathogenesis: the manner in which a disease develops/ how the disease develops
2. Epidemiology: Bigger picture - whole population vs individual
Study of spread, control, and prevention
Compile data to describe the disease outbreak
Research leads to a change in behavior
-Hand washing
-waste removal
-water treatment
3. communicable/contagious disease: any disease transmitted either directly or indirectly by an
infected object from one person to another.
4. reservior: disease present in habitat , water , humans, soil
5. Transmission: Transfer, such as of a disease, from one person to another
water, food,mother
6. incidence: The number of new cases of a disease in a given population during a specified period.
1/4
, fraction of the population that contracts a disease over time
-new cases/total population in a defined time period
7. Prevalence: fraction of a population having a specific disease at a given time-
in a defined time period
8. Endemic disease: Disease constantly present in a population/common cold /influenza
9. epidemic disease: disease acquired by many hosts in a given area in a short time
refers to an unusually large number of cases that can be from an introduced disease or from endemic (what is your
reference
10. Pandemic: worldwide epidemic (AIDS)
11. CDC: Centers for Disease Control and Prevention
12. case reporting: health care workers report specified disease to local, state, and national oflces
13. Nationally notifiable diseases: physicians are required to report occurrence( in other countries
diseases are notifiable that are pretty much unheard of here
14. Morbidity: cases of a specific notifiable disease(typically total cases to assume this)
