Unit 3
Infectious Disease
Sexually Transmitted Diseases

2. Words To know
Infectious Disease : disease caused by an agent that can pass from one living thing to another
Communicable Disease : an infectious disease that is passed from one person to another
Microorganisms : a living thing that can be seen only with a microscope
Pathogens : any agent that causes diseases
2 most common pathogens Other Pathogens
1. Bacteria fungi
2. Viruses protists
- parasitic worms

3. Types of Bacteria (common)
A type of microorganism that can cause disease, majority are harmless
Can kill bacteria with antibiotics
Types of Bacteria (common)
Strep throat
Food/water poisoning
urinary-tract infection
sinus infection
Tuberculosis

4. Types of viruses (common)
A microscopic disease causing particle consisting of genetic material and a protein coat
Attacks and kills living cells to make new viruses
NO CURE
Types of viruses (common)
mononucleosis - measles
hepatitis - common cold
influenza - chicken pox
HIV & AIDS - cold sores

5. Other pathogens Types of Fungi athlete’s foot, jock itch, ringworm
Types of Protists
one cell organism (malaria, west nile)
Types of Parasitic Worms
tapeworm, liver fluke (snails), trichinosis (from pigs - pork foods)

6. How are Infectious Diseases Spread?
1. Through the air
2. Contact with Contaminated Objects
3. Person to person
4. Food and Water
5. Animal Spreading Diseases
From infectious and/or communicable diseases the body will either have an infection or a disease.

7. Defenses Against Infection
Ways our body copes with infection:
Skin
Chemical Warfare on Germs
Mucus Membranes
Stomach Acids
Helpful Microorganisms
Your Immune System

8. Your Immunity Protection against developing a certain disease.
Immune system – protects body from disease
Immunization – injection of a small amount of a pathogen that will provide protection against an infections disease
Antibiotics – drugs that kill or limit the growth of bacterial not viruses.

9. How the Immune System Works
Pathogens – any agent that enters the body
Macrophage – first attacks and activates Helper T
Helper T cells – regulates the actions of T Cells
Killer T cells – kills or neutralizes pathogens
B cells – recognizes the size & produce antibodies
6. Antibodies – sticks to the pathogen & slows action
7. Suppressors T cells – turns off immune system
Memory T cells – recognizes agent & immediately attacks

10. Trends in Sexual Risk Behaviors Among High School Students
Each year 3 million cases of STD in teens in U.S.
