2 Infectious disease: (also called communicable) Infectious diseases are caused by (micro)/organisms or viruses that enter the body and multiply.Not all microorganisms are harmful or cause disease. Some are helpful and essential for good healthPathogens (germs): microorganisms and viruses that cause disease
4 Bacteria Single celled organisms found everywhere Treated with antibiotics to kill or control growthGood and bad typesBacterial infections: tetanus, TB, strept throat, sinus infection, staph, cholera, anthrax
5 Virus Extremely small organism Can’t cure with medicine Some preventable through vaccinesViral infections: cold, flu, chicken pox, warts, cold sores, West Nile, hepatitis
6 Fungus Relies on other living or dead organisms to survive Includes yeast, molds, mildewInclude: athletes foot, ringworm, jock itch, yeast infections
7 ProtozoaAn organism that uses other living things like, your body, for food and a place to live.Protozoa are single celled parasitesDiseases include: tapeworm, malaria, and amebic dysentery, trichina worm (pork)
8 MRSA Methicillian Resistant Staphyloccus Aureus A deadly strain of bacteria that’s becoming resistant to common antibioticsInfects 90,000 Americans a year and is increasingKills 19,000 Americans a yearSymptoms include: warm and tender skin, sores, boils, draining puss, redness, swelling, and high feverLeft untreated can destroy muscle tissue and lead to life threatening infections in bones and vital organsIn the past, it was typically acquired in the hospitalsBecoming very common in homes, schools, locker rooms, and health clubsAthletes are at higher risk because of their environment and physical contact in their sport
10 Protecting Yourself From MRSA Cover cuts and open soresWash hands with warm soapy water oftenClean surfaces and other areas with bleach solutionsBe vigilant with doctorsIn the gym:Don’t share items like towels or razorsCover cuts, scraps, and soresDon’t go barefoot in locker room or showers – wear flip flopsShower immediately after gym or locker roomWash gym clothes to kill bacteria instead of putting back in locker
11 How Pathogens are Spread Infected People: direct contact with person like shaking hands, other bodily contact, and kissing or indirectly like coughing or sneezing where the pathogens are airborne.Contaminated Objects (fomite): some pathogens can survive for a period of time on objects such as door knobs, towels, needles, and glasses
12 Infected Animal: animal that are infected can pass disease through bites. Examples include malaria, West Nile, lyme disease, and rabiesContaminated Food & Water: Some pathogens are naturally present in food and soil. Proper food preparation can prevent disease. Contaminated water is a another big source of disease like cholera and hepatitis A.
14 Physical Barriers Help keep germs from entering the body Skin: keep germs from getting in body and sheds taking germs with it. Sweat acts as chemical barrier which contains acids that kill many bacteria.Hair and Cilia: tiny hairs around eyes and nose trap germs. Cilia are tiny hairs that line mucus membranes like in your air passages. They move pathogens out back out of your airway.Saliva &Tears: trap pathogens and wash them away. They also contain chemicals that attack pathogens.Mucus: sticky substance that trap germs found in your nose and other areas that have openings.Digestive System: chemicals like acid in your stomach that kill many pathogens
15 Internal Defense The Immune System Battles the germs that get by the physical barriers.Consists of different cells and antibodies that engulf and destroy germsImportant to keep our immune system strong through a healthy diet, plenty of rest, and stress management.
16 Prevention tips to minimize transmission of germs Keep contact to a minimum with those who have a coldWhen you come close to someone who has a cold, wash your hands thoroughly with soap and water as soon as possibleKeep hands and fingers away from nose, mouth and eyesDon’t share food, drinking glasses or eating utensilsWash plates, glasses, silverware in hot soapy water after each useGet plenty of rest and eat healthy, dress appropriately for weather, and manage stress to strengthen immune systemVaccinations
