Diseases Non Infectious & 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 Diseases People 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.

People come in contact with pathogens through: 2. Contact with a contaminated object: some can survive for a period of time outside a person’s body – door knobs, cups, pens Some 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

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 - 100 x 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”

Pathogens are Micro-Organisms that cause disease: BACTERIA – single celled microorganisms that can live almost ANYWHERE!! - air, soil, food, plants, animals, objects, on HUMANS!! * Antibiotics can fight against bacteria
