Communicable Diseases and You What is a Disease? • A disease is a condition or illness that affects the proper and usual functioning of the body or mind of an individual. Non-Communicable Disease • A Non-communicable disease I NOT spread by contact with others and may be caused by living conditions, genetics, or environmental hazards. What is a Communicable Disease? • A communicable disease is one that can be passed from one individual to another. • A communicable disease is caused by an organism so small it can only be seen by using a microscope. GERMS • Disease causing organisms are usually called GERMS. • When germs enter the body, they grow, reproduce and frequently produce waste products that are poisons in the human body. • The result is an infection. Types of GERMS • • • • • Bacteria Viruses Rickettsia Fungi Protozoa BACTERIA • Any tiny single cell organisms that grow and thrive almost everywhere. • There are 3 types of bacteria: Bacteria • Cocci • Bacilli • Spirilla VIRUSES • Are the smallest and simplest forms of life. • Many viruses are harmful to humans. • VIRUSES RICKETTSIA • Are small bacteria that are spread by the bites of insects such as mites and ticks. FUNGI • Are simple life forms that are unable to make their own food. PROTOZOA • Simple, animal-like organisms. BACTERIA • Live everywhere: on you, in you, and around you. • Most bacteria do not harm you. • Some bacteria are very helpful. • Bacteria become harmful when they go places they do not belong. E coli BACTERIA need… • Food Supply • Warmth • Moisture • Your body provides all three of these needs and a perfect home for bacteria! BCATERIA COCCI • Can cause diseases such as abscesses, gonorrhea (clap), bacterial pneumonia, strep throat and scarlet fever. BACTERIA BACILLI • Causes botulism (food poisoning), diphtheria, tetanus, tuberculosis, whooping cough, and leprosy. VIRUSES • Are very specialized • Some attack only certain body cells. • Rabies virus attacks only the nervous system. • Viruses cause AIDS, chicken pox, measles, colds, flu, mumps, polio, viral pneumonia, and mononucleosis… RICKETTSIA • Are found in lice, mites, and ticks. • They enter the body through the bite of an insect that is infected. • Rocky Mountain Spotted Fever, and Lyme Disease are caused by rickettsia. • Lyme Disease FUNGI • Attack the body and often live in the hair, nails and skin • Athlete’s Foot and ringworm are two diseases caused by fungi. • Athlete’s foot affects the feet, while ringworm appears on other parts of the body. • Ringworm PROTOZOA • Many are harmless but some can cause disease. • Malaria is caused by protozoa that live in certain kinds of mosquitoes. • If an infected mosquito bites a person, the person will become infected.
