Chain of Infection
What is the Portal of Exit?
A way a pathogen might escape its reservoir/host
Explain the difference between Communicable and Chronic Disease....
Communicable is infectious, Chronic is not.
Define: White blood cells
Cells that fight disease causing organisms.
What is the bodies first line of defense?
Physical Barriers
What is the Mode of Transmission?
How a pathogen travels (direct contact, indirect, airborne, animal vector etc...)
What is the number one cause of premature death for adults in the USA?
Heart Disease
A disease causing organism.
What is the bodies second line of defense?
Innate Immune Response
Name TWO specific populations that are typically vulnerable to communicable disease...
Elderly, infants, immune compromised
What is the Chronic Disease that is ACQUIRED that affects the bodies ability to use glucose of energy.
Diabetes Type II
Define Immunity
Having the white blood cells counts to effectively fight off pathogens
Define the Bodies innate immune response...
A general, non-specific response to a pathogen.
What is the Reservoir and one example of a Reservoir?
Where a pathogen grows and survives. One EXAMPLE: Specific animal hosts, water, soil, fluids....
What is a general definition of Cancer?
Uncontrolled growth and spread of abnormal cells.
Define Vaccine.
Injection of a weakened or dead pathogen.
What is the bodies 3rd line of defense?
Adaptive immune Response
Explain the chain of infection for COVID-19:
Infectious Agent:
Reservoir:
Portal of Exit:
Mode of Transmission:
Portal of Entry
Susceptible Host:
Infectious Agent: COVID-19, coronavirus
Reservoir: Bats, Human lungs
Portal of Exit: Mouth/nose, respiratory excretions
Mode of Transmission: Air droplets, direct contact
Portal of Entry: Mouth/nose, inhaled through respiratory tract
Susceptible Host: Elderly, infants, immune compromised
Define Hypertension and Coronary Artery Disease...
High blood pressure, and collection of fatty substances in the arteries.
Name the 4 different types of pathogens...
Virus, Bacteria, parasite, fungus
Explain the relationship between vaccination and adaptive immune response....
