3 Itchy bugs Top 14 Scabies Ringworm Clostridium difficile Methicillin-resistant Staphylococcus aureus (MRSA) Impetigo (Step/Staph) Bacterial

3 3 Itchy bugs Top 14 Scabies Ringworm Clostridium difficile Methicillin-resistant Staphylococcus aureus (MRSA) Impetigo (Step/Staph) Bacterial conjunctivitis Pertussis Meningococcal meningitis Hand, foot and mouth Chickenpox Measles Mumps Fifth disease Flu Influenza Stomach flu Norovirus

4 Infestation of the skin 4 Female burrows into the upper skin layer

5 Human scabies human itch mite 5 Sarcoptes scabiei var. hominis

6 Intensely pruritic skin infection 6 Moderately contagious Adults 1/3 millimeter long Inactive below 20 o C (68 o F) At 20 o C mites can persist for 2 weeks

7 7 Spread by direct, prolonged, skin-to-skin contact

8 8 Infection occurs due to the direct transfer of a single fertilized female

9 Life cycle days 9 Remain viable for 3 days on inanimate objects (>22 o C, 72 o F) Transmission via articles is possible, but unlikely

10 10 Burrows and malformed fingernails may or may not be evident

11 11 An affected host harbors only adult mites - typical infestation Skin scrapes are the only way to positively identify mites

12 12 Hypersensitivity reaction to the mites, molts, eggs, or scybala occurs about 30 days after infestation

13 13 Disproportionately affects women and children Secondary bacterial infection is common Staphylococcus aureus Streptococci Peptostreptococci

14 14 Immunocompromised prone to develop crusted scabies

15 Usually below the neck - adults 15 Fingers, flexor surfaces of the arms, wrists, axillae, and the waistline Umbilicus, nipples, penis, and scrotum

16 Infection eliminated using 16 prescription treatments Once treatment starts individuals are not infectious

17 Treatments 17 Permethrin (e.g. Elimite) Lotion applied over body from neck down Left on for 8-12 hours, then rinsed off Reapplication 1 week later Clothes dryer will kill mites

18 Treatments 18 Crotamiton (e.g. Eurax; Crotan) frequent treatment failure has been reported Lindane lotion is NOT recommended

19 Relief from itching 19 Antihistamine diphenhydramine Itching becomes worse after mites die

20 Inappropriate things 20 OTC pesticides applied to rooms or buses Incorrect use of sterilants or disinfectants applied to room surfaces

23 Antimicrobial products are pesticides 23 Slows growth Stops growth Kills some in time Kills some quickly Quickly = <10 minutes Kills all quickly

24 24 Microorganisms bugs Have only 2 jobs: Survive Reproduce

25 Ringworm - fungal skin infection 25 Dermatophytes live off dead tissues (skin, hair, and nails) Scaly, crusted rash May itch

26 26 Moist areas Children Warm, moist climates Contagious Tinea capitis Tinea faciei Tinea barbae Tinea manus Tinea cruris Tinea unguium (nails) Tinea corporis Tinea pedis Contracted from an infected person, animal, object, surfaces, or soil

27 Transmitted from animals to humans 27 Class pets Exclude feral cats from classrooms

28 28 Immunocompromised individuals should not be around ringworm

29 Clean hard surfaces with disinfectant 29 Carpeted areas vacuumed Prescription antifungal medications before returning to contact sports Medications - topical and/or oral

Students should be referred to a doctor 1.

30 Students should be referred to a doctor Can persist on skin, hard surfaces, and on items such as clothing, towels, furniture and bedding Spores can survive >year

31 Students should not participate in 31 contact sports until treated Wear sandals or slides in showers and locker rooms Discourage sharing towels and clothing

32 Campus animals Must be spayed/neutered, vaccinated and maintained in good health

35 Clean Cleaning removes pathogens and dirt Sanitation reduces the number of diseasecausing organisms to non-threatening levels Disinfection destroys microorganisms, does not kill all pathogens Sterilization kills all disease-causing pathogens

You NEED to know 1. 1. 1. 36 1. What are you doing? 2. What product? 3. What are you killing?

36 You NEED to know What are you doing? 2. What product? 3. What are you killing? 4. What are you treating? 5. What concentration? 6. What length of time? 7. What next?

37 Custodians 37 5 billion pounds cleaning chemicals annually (25% hazardous substances) One custodian uses, on average, 194 pounds of chemicals / year Custodians and teachers experience some of the highest rates of occupational asthma

38 6% of custodians are injured annually 38 20% burns to the eyes or skin 12% inhaling vapours

39 Disinfectants and sanitizers 39 Higher Chlorine / Sodium Hypochlorite Lower Phenols Quats Peroxide EPA Sanitizer Superior health & environmental profile

40 Environmentally preferable purchasing (EPP) 40 EPP = Environment + Price + Performance

41 What are green cleaners? 41 Lower toxicity No cancer-causing ingredients or asthmagens Not corrosive to eyes or skin or skin sensitizers Won t pollute air or deplete ozone layer Won t kill fish Will biodegrade Low phosphorous Package recyclable Available as concentrate Limits on fragrances used Certain ingredients prohibited e.g, phthalates Performance tested Vendor training available

42 42 Infection interruption from contaminated environmental surfaces Increase frequency of cleaning frequently touched surfaces

43 Sanitation for norovirus and influenza 43 Influenza virus survives on surfaces 2-8 hours Norovirus survives on surfaces 2 weeks Destroyed by heat ( F), chemical germicides: chlorine, hydrogen peroxide, detergents, iodophors, alcohols Concentration and length of time

44 Sanitation steps Wash surfaces with general cleaner to remove dirt and organic matter first Follow label directions Rinse with water if instructed EPA approved disinfectants

45 45 Clean hands constantly Alcohol wipes and gels Cover coughs and sneezes - droplets can move through the air 3-6 feet

46 If using chlorine bleach tablespoon of bleach to 1 quart (4 cups) of water, or ¼ cup of bleach to 1 gallon (16 cups) of water Apply solution to surface with a cloth Let it stand for 3 to 5 minutes Rinse with clean water

47 Wipes used on items that are touched 1.

47 47 Wipes used on items that are touched often Door handles Phones Computer keyboards

48 48 Many disinfectant wipes are registered pesticides Students should not clean surfaces with disinfectant wipes Surface disinfectant wipes are not hand wipes Many labels clearly state KEEP OUT OF REACH OF CHILDREN

49 Tissues thrown in trash or bagged Persons cleaning classrooms or emptying trash wear gloves, then wash hands

50 50 Norovirus is leading cause of food-borne illness Sick staff or those caring for others who are sick should not prepare food Infected food workers cause 70% of reported norovirus outbreaks Very contagious

51 Hand washing is critically important Found in vomit or stool even before a person is sick, and for 2-3 weeks after symptoms abate Alcohol-based hand sanitizers used in addition to hand washing

52 Impetigo 52 Highly contagious Caused by Staphylococcus aureus and/or Streptococcus pyogenes Red sores on the face, around nose, mouth, hands and feet Sores burst and develop honey-colored crusts Itchy

53 53 MRSA Methicillin-resistant Staphylococcus aureus Spread through cuts, abrasions and skinto-skin contact Contaminated surfaces Begins as painful/itchy boil

55 Clostridium difficile (C-diff) 55 After antibiotic therapy Diarrhea Pseudomembranous and toxic colitis Fever Abdominal pain Cramping Nausea and loss of appetite

56 Managing Clostridium difficile 56 Spores highly resistant to cleaning agents Survive for 5 months on dry surfaces Handwashing Killed by chlorine bleach Isolate infected individuals

57 57 >23,000 Americans die annually from antibiotic resistant infections Resistance occurs when antibiotics are used: Appropriately Food and water (waste) Our environment Inappropriately (e.g., vial infection)

58 Resistant infections 58 Antibiotic Ribosomes Plasmid Impermeable protein Inactivation Added phosphate group reduces ability to bind Pumping out Increasing active efflux Modified target site

59 59 CDC: washing hands with soap and water is effective Increasing incidence of super bugs Avoid triclosan absorbed through the skin and bio-accumulates, linked to liver damage and resistant bacteria 1 (800)
