An Epidemiologist is a scientist who studies diseases
including how they start, spread and how they are treated.
Who Figures All of This Out?
• Body must fight off virus on its own!• Vaccinations can help
used to control spread of viral diseases a solution that contains weakened virus
particles is injected into body body makes antibodies against that virus** Viruses MUTATE from year to
year producing new strains SO..vaccines YEARLY!!

Contagions
4 main ways that pathogens are transferred:◦Person to person
◦Food and water
◦Environment
◦Animals
How do pathogens spread?
Moist◦ A lot like water
Average temperatures◦ Not too hot or too cold (EXTREME)
Limited exposure to fresh air◦ More ability to reproduce
Sunlight◦ Good for some, bad for others
Food sources◦ Sugars or decaying material
Environments for “SURVIVAL”
RegionalKnown disease that infecting more
individuals than usual
GlobalLarge % of individuals infectedUsually viralNew disease to humans

Epidemics & Pandemics
Each person will receive a test tube and a syringe
You will carefully go around the room and trade fluids with 3 other people using your syringe
When completed, sit down and write down who you traded with first, second and third
Finding Patient Zero
Purple/clear = Negative
Blue/green = Positive
