Infectious Disease

Non-Infectious Disease

Disease NOT caused by contact with person, object, animal or substance

NOT contagious Caused by RISK FACTORS – behavioral,

environmental, hereditary Examples: cancer, diabetes, heart

disease, stroke, high blood pressure

Infectious Disease

Caused by micro-organisms that enter, live in, and multiply within the human body. Examples: Mono, Rabies,

Chicken Pox, Measles, Colds, Flu

The Spread of Infectious DiseasesPeople come in contact with pathogens through:

1. Contact with an infected person: directly or indirectly – hugs, kisses, touching, sneezes, coughing

sneeze – an expulsion of air from the nose and mouth. This air can reach speeds of 70 mph and an unimpeded sneeze sends two to five thousand bacteria-filled droplets into the air.

2. Contact with a contaminated object: some can survive for a period of time outside a person’s body – door knobs, cups, pensSome viruses and bacteria can live from 20 minutes up to 2 hours or more on surfaces like cafeteria tables, doorknobs, and

desks. (Ansari, 1988; Scott and Bloomfield, 1989)

People come in contact with pathogens through:

3. Contact with an infected animal: some disease can be spread by animals – rabies, malaria

People come in contact with pathogens through:

The Four Ways Infectious Diseases Enter The Body

1. Air we breathe

2. Swallowing

3. Breaks in the Skin

4. Moist linings of eyes, ears, nose, mouth

Preventing Infectious Disease

1. AVOID contact with pathogens

2. GET IMMUNIZED with a vaccine shot

3. CHOOSE healthy behaviors – get sleep, eat healthy, DON’T SHARE items, WASH HANDS!!!!!

Pathogens are Micro-Organisms that cause disease:

VIRUS: the smallest pathogen- 100x smaller than bacteria- can multiply only by entering

into a living cell- different types of viruses enter

different types of cells- cannot just “get rid of it”

BACTERIA – single celled micro-organisms that can live almost ANYWHERE!!

- air, soil, food, plants, animals, objects, on HUMANS!!

* Antibiotics can fight against bacteria

What do you have to remember when washing your hands???

HANDWASHING is the #1 way to prevent the spread of infectious disease!!!

40% of food borne illness is the result of poor handwashing

Germs are STICKY – use soap and water

20-30 seconds or as long as it takes to sing Happy Birthday 2x

Warm water makes more bubbles to lift germs away

What do you have to remember when washing your hands???

Wash your hands – before eating, before preparing food, after going to the bathroom, changing diapers, touching animals, shaking hands, taking out the trash, after smoking, working, playing,

Use paper towels to turn

off faucets and open doors

to prevent re-contamination
