1. Epidemiology & Microbiology Review

2. Terms Epidemiologist Studies how a disease spreads in a population
Try and find patient zero

3. Diseases Infectious Noninfectious Communicable Are caused by microbes
Contagious
Examples:
Flu
Strep throat
Salmonella
Noninfectious
Non-communicable
Caused by lifestyle choices, environment, genes or a combination of factors
Not contagious
Examples:
Diabetes
Cancer
Sickle Cell Anemia

5. Vector
Any organism (other than a human) that spreads a disease without showing symptoms of the disease themselves.

6. How can Infectious disease spread?
Direct Contact
Occurs when there is physical contact between person to person (bodily fluids touching bodily fluids)
Examples:
Kissing
Sexually transmitted
Brest feeding
Open wounds…
Indirect Direct
Occurs when NO direct human-to-human contact is made
Examples:
Sneezing
Airborne droplets
Contaminated surfaces
Sharing drinks

7. Infectious Diseases Prevention Treatment
Ways to avoid ever getting sick (or infected) with the microbe
Examples:
Vaccines
Hand washing
Eating right
Personal Hygiene
Vitamins
Ways to try and cure a disease or manage the symptoms of a disease
Examples:
Antibiotics (Penicillin)
Rest
Fluids
Medicine

8. Infectious Diseases Epidemic Pandemic Local spreading of diseases.
Examples:
Outbreak in a school
Outbreak in a town
World/Global spreading of diseases
Examples:
A disease spread over several countries

9. Pathogens – Microbes (agents) that cause a disease
Bacteria
Virus
Living
Unicellular
Prokaryotic
Reproduction:
Binary Fission (Asexual)
Some are heterotrophs and some are autotrophs
Some can use flagella for movement.
Not living
Unicellular
Needs a host to reproduce
Lytic Cycle (Asexual)
Parasite
Doesn’t need food- Not living
Very Small!!!

10. Germ Theory of Disease Who? What does it say? Louis Pasteur
Infectious diseases are caused by Microbes

11. Spontaneous Generation
Says that…
Living things come from nonliving things
Not true!

12. Cell Theory All living organisms are made of cells.
Cells come from other cells
The cell is the basic unit of life in living things carrying the heredity information (DNA) of the organism of which they are apart of.

13. Life Kingdoms
Animal
Plant
Protist
Bacteria
Fungi
