Who we are Presenting to Age: 6th Grade Students Sex: Equal boys and girls Socioeconomic status: Primarily white middle class with other students from mixed backgrounds
Objectives • Define infectious disease • How are infectious diseases spread? • How does your body fight disease? • Immunization • Common infectious diseases • Common sense
You will be able to… • Define the term infectious disease • List 3 common modes of disease transmission • Recognize situations in which disease transmission is likely to occur
You will be able to… • Name 1 way to help keep your immune system response high • List 2 differences between active and passive immunization • List 2 differences between nonspecific and specific resistance.
Why we are here Infectious disease is something that everyone comes in contact with. We need to know how to protect ourselves and those around us!
What is an infectious disease? An infectious disease is a disease caused by organisms that enter and multiply within the human body
What is an infectious disease? • These microorganisms are also known as pathogens • pathogens are bacteria, viruses, rickettsias, protozoans, and fungi • They are so small, you can not see them with the naked eye
How infectious diseases spread Direct and Indirect methods from: • humans to humans • animals to humans • plants to humans
Direct Sneezing Coughing Touching Mother to unborn baby Indirect Touching something that is infected Drinking after someone with an infectious disease Human to Human
Direct Eating animals Bugs biting you Getting scratched by an animal Getting Stung Indirect Petting animals then touching your mucous membrane Drinking water after an infectious animal Animal to Human
Plant to Animal • Eating unwashed fruits and vegetables • Touching fruits then putting your fingers in your eyes or mouth
Ways To Avoid Spreading Disease • Wash You Hands a lot • Cover your mouth with a tissue when you sneeze or cough • Don’t let people drink after you • Keep your fluids to yourself
Ways To Avoid Catching An Infectious Disease • Wash your hands • Protect yourself against bugs • Wash fruits and vegetables before you eat them • Do not drink or eat after anyone • Don’t eat undercooked meat or eggs
Your Body How does your body fight off infectious disease? Your Immune System!
Immune Response • Nonspecific Resistance • External-skin & mucous membranes • Internal-inflammation, interferon, natural killer cells,
Immune Response • Specific Resistance • Lymphocytes • Memory Cells • Effector Cells • B-Cells • Antibodies
Immune Response • Specific Resistance • Cell Immunity • T-Cells • Helper T-Cell Activation • Cytotoxic T-Cell Activation
Taking Care of Your Immune System • Good Nutrition • Wash food • Refrigerate foods that spoil • Take Vitamins • Eat healthy • Immunization
Immunization • What is Immunization? • Help for the body’s defense system • There are 2 types • Passive • Active
Passive Immunization • Immediate protection • Short lived • Blood with antibodies taken from host
Active Immunization • Known as vaccination • Causes antibodies but not disease • Two main types • Live-virus • Killed-virus
Live-Virus Vaccines • Contain living viruses • Genetically weakened • Weakened through animal filtering
Killed-Virus Vaccines • Contained killed viruses • Less powerful • Booster shots • Typhoid fever, Cholera, Rabies
Immunization Importance • State by state law • Needed for work and school • Diseases still there
Common Infectious Diseases • The common cold • Influenza • Strep throat • Mononucleosis • Can you list more?
Symptoms of the Common Cold • The Common Cold • Mucous buildup making it hard to breathe • Swelling of sinuses • Sneezing • Sore throat • Coughing • Headache
Symptoms of Influenza • (Flu) • Respiratory Tract Infection • Chills • Fever • Headache & muscle ache • Weakness • Dry throat • Fever (100-104 degrees F)
Symptoms of Strep Throat • “Strep” • Fever • Enlarged lymph nodes • Pain when swallowing • Malaise (feeling sick) • Headache • Nausea, vomiting and abdominal pain in children
Symptoms of Mononucleosis • “Mono” • Fever • Sore throat • Enlarged lymph nodes • Drowsiness • Loss of appetite • Muscle aches • Enlarged Spleen
Keep your body healthy Store and prepare food safely Avoid sharing food Treat illnesses and cover mouth when sneeze Throw tissues in trash can Shower every day Common Sense
When I cough or go kerchoo, This is what I always do. I cover my mouth with a tissue, So my germs won't get on you! Common Sense
Disease will still spread No matter how many precautions you take, you can still get a disease. Its not your fault!
