1 Germs and DiseaseDisease-any condition that interferes with the proper functioning of the body or mind.Communicable disease-disease that can be spread to a person from another person, animal, or object.Germs-organisms that are so small that they can be seen only through a microscope.Pathogens-germs responsible for causing diseases.Infections-condition that occurs when pathogens enter the body, multiply, and damage body cells.
2 Types of PathogensViruses-the smallest and simplest disease-causing organisms, causing a wide range of health problems.AIDS Influenza RabiesChicken Pox Measles SmallpoxColds Mononucleosis ViralHepatitis Mumps PneumoniaHerpes Polio
3 Types of PathogensBacteria-tiny one-celled organisms that live nearly everywhere. Some are harmless and some are helpful, but can cause disease.Bacterial pneumoniaDiphtheriaFood borne illnessGonorrheaLyme diseasePinkeyeStrep throatTuberculosis
4 Types of PathogensFungi-primitive life-forms, such as molds or yeasts, that can’t make their own food.Athlete’s footRingworm
5 Types of PathogensProtozoa-one-celled organisms that have a more complex structure than bacteria.Amebic dysenteryMalaria
6 How Pathogens Are Spread Direct contact with others.Skin to skin contact.Colds are spread if you touch someone’s hand that has sneezed or coughed into their hand, then you touch your eyes or nose.Indirect contactBreathing in germs from a sneeze.Sharing drinking glasses, food, eating utensils.Touching a surface that is contaminated, doorknob, phone, ect.
7 How Pathogens Are Spread Contact with animals or insects.Being bit by a rabid animal.Being bit by a deer tick may transmit Lyme disease.Contaminated food and water.Undercooked meat may result in E. coli bacteria, which could result in death.
8 How Pathogens Are Spread Contact with someone else’s blood.Through body contact or sharing of needles.HIVHepatitisSexual contact.Certain diseases are transmitted through sexual contact.We will discuss this more in Lesson 4
