  1. Hand Hygiene to Prevent the Spread of Disease Lynn Nakamura-Tengan Extension Educator

  2. What will be covered • Basic information about germs • Types • Modes of transmission • Importance of hand washing • When to wash • How to wash • Alternative hand hygiene options • Products available • Implementation in local settings

  3. Germs-microscopic organism • Bacteria • Viruses • Fungi • Protozoa

  4. Bacteria • a single cell • helpful, pathogenic (harmful, causing disease), and spoilage (deteriorates food) • balls, rods, or spirals • Salmonella, Staphylococcus aureus, Streptococci • Some bacteria produce poisons called toxins -Clostridium botulinum bacteria Streptococci Bacteria Source: National Institute of Health-NIAID

  5. Viruses • Viruses are smaller than bacteria • Viruses are protein structures, not cells • Require a living host to survive • Highly infectious • Viruses can be rod-shaped, sphere-shaped, or multisided, common examples:Hepatitis A, Norwalk virus, influenzavirus

  6. Fungi • primitive vegetable • found in air, in soil, on plants, and in water • familiar ones - mushrooms, yeast, mold, and mildew • Some live in the human body, without causing illness • Some are beneficial - penicillin and yeast for fermentation

  7. Protozoa • microscopic one-celled animals • Protozoa can be parasites or predators • In humans, protozoa usually cause disease • Examples: Malaria - a protozoan parasite, Trichinia spialis (pork and wild game meats), Giardia lamblia (contaminated water and anything it contacts)

  8. Person to person • Cuts, abrasions, wounds • Insects – mosquito (Dengue, West Nile), flea (plague) , tick (Lyme disease) • Water – e-coli, Cryptosporidia, Giardia and Salmonella • Pets – dogs & cats (rabies), reptiles (Salmonella) Germs: modes of transmission

  9. Air - cough and sneeze • Hands Germs: modes of transmission

  10. Germ enter your body - hands • Hands to food – unwashed hands preparing foods • Hand to hand – shaking hands • Food to hands to food – raw poultry to ready to eat foods • Food to hands to infant – diaper changing to infant • Nose, mouth or eyes to hand • Hands to nose, mouth, eyes

  11. Germs enter your body - other • Insects such as mosquitoes, fleas and ticks • Animal bites • Open cuts, abrasions, or wounds; treat and cover wounds immediately.

  12. Avian Flu Greatest risk from handling & slaughtering infected poultry • Do not eat sick or dead poultry • Do not touch sick or dead birds without gloves • Do not let children touch or play with sick or dead birds or their feathers • Do not sell or buy birds from infected area • Do not move sick or dead birds out of an infected area • Do not drink unboiled/treated water from areas with bird droppings • Do not swim in waters used by wild birds birds m

  13. Hand hygiene is the primary measure to reduce infections…” Soaps - designed to clean the skin by removing dirt, oils and germs. Antibacterial soaps - contain Triclocarbon and Triclosan, for added germ killing protection Hand sanitizers – waterless, include a germ kill ingredient: alcohol, Triclocarbon, Triclosan Handwashing

  14. When to wash your hands • Before and after eating, drinking, smoking or chewing tobacco products • After going to the bathroom • After changing diapers or cleaning up a child who has gone to the bathroom • Before and after tending to someone who is sick • After blowing your nose, coughing, or sneezing • After touching hair, face or clothing • After handling an animal, animal parts or animal waste • After handling garbage, cleaning products, pesticides, fertilizers, soil • Before and after treating a cut or wound • Anytime hands look dirty

  15. Hand washing Experiment • Break up into 6 groups • Liquid soap and water • Foam Soap • Water only • Alcohol sanitizer • Chlorine sanitizer • Hand wipes • Apply “Pretend Germ lotion” • Clean hands as directed for your group • Record results of your hand hygiene • Discussion on findings
