Emerging Diseases Some appear to be old diseases that have returned

48 Check your vaccine records
Get your records from: Previous employer High school College Training program

49 New Hires Review for protection
Not protected – offer prevention up front At least 90% less costly than one exposure

50 Current Staff Collect data on childhood diseases or vaccine
Offer vaccine to unprotected staff

51 C- diff Anaerobic spore-forming bacillus
Clostridium difficile-associated disease (CDAD) Hospital-acquired Related to antibiotic treatment

52 Transmission Fecal – oral Contaminated hands
Contamination of environment Mayo Clinic, 2006, HIC, 2008

53 Signs/Symptoms Diarrhea (watery) Fever Loss of appetite Nausea
Abdominal pain/tenderness

54 New Information – C-diff
Soap and water for handwashing when caring for a patient with C-diff is more effective than using alcohol hand sanitizers Infect. Control Hosp. Epidemiology. 2010, June 31 (6):571-3

55 Cleaning Chlorine based product is needed

56 Treatment Most cost effective

57 Fecal Transplant The fecal microbiota transplantation (FMT) movement is catching the attention of scientists, researchers and the media nationwide. Currently, fecal transplantation delivers pre-screened, healthy human donor stool to a patient via colonoscopy or by nasogastric tube. It’s prescribed as an effective alternative to long-term antibiotic use in treating debilitating infectious diseases such as Clostridium difficile, also known as C-diff. new research published in Journal of the American Medical Association says there is a third, less invasive, less expensive option to treat C-diff: poop in a pill.

58 Carbapenem-Resistant Enterobacteriaceae (CRE)
New Delhi/Verona Majority of cases in persons hospitalized outside the U.S. overnight within 6 month time frame Occurs in patient receiving antibiotics and other significant medical treatments

59 Travel History Have you ben hospitalized overnight outside the United States in the past 6months

60 Exposure No follow up needed or recommended
Healthy people usually do not get CRE infections CDC, 2013

61 CRE Have developed high levels of resistance to antibiotics including “last resort” antibiotics – carbapenems S/S: fever, fatigue, UTI, sepsis

62 Prevention Prudent use of antibiotics Remove unnecessary devices
Good handwashing Contact Precautions Cleaning equipment

63 Current Outbreak in US UCLA Medical Center – (2015)
Hospital NorthWesten Illinois – 39 cases (2014) Source – duodenoscopes Currently – not a reportable infection

64 Efforts – Antibiotic Resistance
FY 16 budget, CDC has requested funding to support State Antibiotic Resistance Prevention Programs in all 50 states September,2015 expanded to long-term care facilities

65 Middle Eastern Respiratory Syndrome - MERS

66 MERS Coronavirus – usually mild illness
History of travel to Arabian Peninsula in the past 10 days Cleaning – B/W 1:100 post transport CDC Home Care Guidelines

67 Transmission Close contact – caring for or living with an infected person MERS has been found in camels – contact with camels Urine Nasal secretions

68 Persons at Risk Person with pre-existing medical conditions

69 MERS – Signs & Symptoms Fever Cough Shortness of breath

70 Incubation Period 5 – 6 day ( can be days)

71 Prevention Place surgical mask on the patient Good handwashing

72 Post Exposure MERS No treatment available
Take Temperature twice daily x 14 days Symptoms – seek medical care

73 MERS in U.S. May 2014 2 cases- very low risk to general population
1 in Indiana 1 in Florida Believed to have been infected in Saudi Arabia Both are healthcare workers in Saudi Arabia Both recovered –

74 Ebola Outbreak

75 Travel History Travel history to Africa or contact with a know or suspect Ebola patient Symptoms – temp 101.5 Part of Patient assessment Standard Precautions Contact Precautions Droplet Precautions Mask patient

76 Medical Facility Africa United States

77 Transmission Human – to – Human Transmission
Direct contact through (broken skin or mucous membranes) with blood, secretions, organs of infected persons Contact with contaminated environments WHO/CDC

78 Incubation Period 2 – 21 days following an exposure event

79 Test for Ebola 2 min. fingerstick test

80 We are fortunate! Fatu Garbage Bag technique

81 Current CDC Recommendations
PPE EMS – pts. Without Vomiting/diarrhea Surgical mask/face shield Double gloves Cover gown CDC Dec. 2, 2014/ 2015

82 Current Approach All persons coming to US from West Africa will enter
the US through 4 airports Ill persons transport (by air) to one of 35 medical facilities

83 Ebola Vaccine Ebola vaccine trial in Guinea shows 100% Merck – ZEBOV
Effective in 10 days after administration World Health Organization reports that a human vaccine trial has ben successful in Guinea. The vaccine is manufactured by Merck. Future vaccine trials are questionable as the Ebola case numbers are so low. That is good news WHO, August 3, 2015

84 Why CDC Guidelines Change

85 Steps in Outbreak Investigation
Establish an outbreak exists Verify diagnosis Define and identify cases Collect data – time, place and person Implement control measures Evaluate hypotheses and conduct studies Evaluate data and revise control measures if needed Communicate findings

86 What We Have Learned We are not ready
Education/training basics are not in place Travel history needs to be routine Fear prevails over science

87 What We Have NOT Learned
Quarantine is broken if – No access to food No access to medications No access to income

88 ZikA Virus Infection The newest vector borne illness that may be heading north to the US

89 Travel History Key information
This should always now be a routine question on patient assessment

90 Mode of Transmission Mosquito bite Blood Sexual Contact (rare)
Infected mother to her child How this is transmitted – you are NOT at risk for contracting this illness as a result of patient care activities Zika virus can be transmitted from a pregnant mother to her fetus during pregnancy or around the time of birth. Regarding sexual transmission - In all three cases, the men developed symptomatic illness.  CDC/WHO

91 Symptoms   About 1 in 5 people infected with Zika virus become symptomatic. acute onset of fever with maculopapular rash arthralgia, conjunctivitis myalgia headache. Clinical illness is usually mild with symptoms lasting for several days to a week. Symptoms that have been noted - CDC

92 Prevention - Women Women who are pregnant –
Updated guidelines include a new recommendation to offer serologic testing to asymptomatic pregnant women (women who do not report clinical illness consistent with Zika virus disease) who have traveled to areas with ongoing transmission of Zika virus Testing should be offered between 2 and 12 weeks after pregnant women return from travel to areas with ongoing Zika virus transmission. CDC recently updated its guidelines and more changes may be forthcoming CDC/WHO

93 Women – Childbearing age
The advisory applies to women of child-bearing age, including Olympic athletes, traveling to Latin America and Caribbean countries. Pregnant women who can't postpone their travel should talk to their doctor first and take precautions to avoid mosquito bites These precautions also apply to women trying to become pregnant or who are thinking about becoming pregnant, because the virus lingers in the body for as long as two weeks after infection. CDC advice to women of childbearing age and those trying to become pregnant (James Gathany/Centers for Disease Control and Prevention 1/15/16))

94 Prevention - Men If there has been travel to an are with active Zika virus transmission – consider using a condom or abstinence if your partner is pregnant the duration of persistence of Zika virus in semen remains unknown. CDC, 2016

95 Mosquito control Use of repellant Air conditioning Clothing
Focus Mosquito control Use of repellant Air conditioning Clothing

96 Treatment Antiviral treatment is not currently available for Zika virus disease; treatment is supportive and includes rest, fluids, and analgesic and antipyretic medications. Aspirin and other nonsteroidal anti-inflammatory medications should be avoided Pregnant women with fever should be treated with acetaminophen. Basic supportive treatment CDC
