 Get
in groups of 4 or 5.
 When I say go, take out the cards
and place the 2 larger cards in front
of you. (Communicable & Non-Communicable)
 Place the smaller cards (Disease) into
the correct category.
 Call me over when you are done.

Communicable Diseases:

Caused by direct or indirect spread of
pathogens from one person to
another. They enter and multiply
within the human body.
Caused by Pathogens
 Bacteria (single cell microorganism)
– They enter the body and multiply
rapidly through cell division. Can live
anywhere – air, soil, water – some
produce toxins.
 Viruses (genetic material coated by protein)
– Are not living cells but attach
themselves to living cells (hosts) and
injects its genetic material into that cell,
makes copies and spreads to other cells
More Causes
 Rickettsias
(similar to bacteria)
– Most are found in the intestinal tracts of
insects (fleas, ticks, mites and also
mice) and are passed through bites or
through feces deposited on the skin.
 Fungi
(plant like organisms)
– Ring worm or athletes foot. They prefer
dark, damp environments and invade
deep tissue like hair, nails and skin.
How are communicable
diseases spread?
 DIRECT
CONTACT
– People, Animals or Environment
 INDIRECT
CONTACT
– Contaminated objects – table, door
handles, eating utensils, tooth brush,
needles, etc.
– Vectors (flies, mosquitoes & ticks) –
transfers pathogens from person to
person
– Water & Food
Prevention
 Wash
hands
 Food Handling
 Strong Immune System
 No Sharing (utensils, make up,
combs etc)
 Contact with people, etc.
 Stress…..
 Immunizations
Bodies Means of Preventing
Communicable Diseases
 Physical
barriers (skin, mucus, cilia
etc)
 Chemical barriers (enzymes in saliva
and gastric juices)
 Immune System Response
– Inflammatory Response
– Antigen – substance that is capable of
triggering an immune response
Extra Credit: Disease Interview
 Interview
someone who suffers or
has suffered from a noncommunicable disease. (family,
friend etc)
 Over phone, in person via email.
 Develop 10 thought provoking
questions and format Q & A’s into
magazine format.
