2 Novel H1N1 influenza: Background information H1N1 outbreak in Anne Arundel County Public Schools, Spring 2009 School response to Novel H1N1 Virus, Fall 2009: Current Contingency plans Potential school design elements to facilitate response to communicable diseases Summary Questions Outline
3 Novel H1N1 influenza: Background information
4 What is influenza? A type of virus that causes respiratory infection with systemic S/S Two types of influenza viruses cause epidemic human disease: Influenza A: Categorized into subtypes on the basis of 2 surface antigens: Hemagglutinin Neuraminidase Influenza B: Two distinct genetic lineages: Yamagata and Victoria Not categorized into subtypes Seasonal vs. pandemic influenza Seasonal Virus changes slightly most years (antigenic drift) Season usually October through May ~200,000 persons hospitalized ~36,000 deaths Pandemic Influenza virus to which most of population lacks immunity Spread to at least two regions in the world
5 Novel H1N1 influenza: Background information N H
6 What is H1N1 influenza? Antigenically and genetically distinct from other human influenza A (H1N1) viruses in circulation since 1977 Inappropriately referred to as swine flu because the virus is related to influenza viruses that affect pigs. The most affected group of persons is under age 24 years. Has spread to all regions of the globe pandemic declared in June 2009.
8 How is influenza spread? Seasonal and Novel H1N1 Respiratory droplets from an infectious individual coughing and sneezing Can travel up to 3 feet in the air Contaminates another person close by Lands on surfaces (fomites), e.g., doorknobs, computer keyboards, faucet handles Infection begins when the virus is introduced to the nose or mouth (mucous membranes)
9 How are people affected? Seasonal and Novel H1N1 Respiratory illness with systemic signs & symptoms: Fever (100°F or greater), cough, sore throat Nasal congestion, muscle aches, headache, chills, fatigue Diarrhea, vomiting (seen with novel H1N1) Usually abrupt onset Typical time to recover is 4 days to one week in healthy people
10 Risk Factors for Severe Disease Immune system disorders HIV, transplant, chemotherapy, etc. Elderly, infants, pregnant women Other medical problems: Lung disease Diabetes Kidney disease
11 Treatment of Infection Seasonal and Novel H1N1 Rest Drink plenty of liquids Avoid drinking alcohol or smoking Use over-the-counter medications Labeled cold and flu remedies Not aspirin In some situations, use antivirals Oseltamivir (Tamiflu), zanamivir (Relenza) Prescription medications Initiate within 48 to 72 hours of first symptoms for optimal effectiveness
12 Preventing the flu Seasonal and Novel H1N1 Clean hands often Soap and water Alcohol-based hand sanitizers Cover your cough/sneeze Use a tissue or your sleeve Avoid close contact with sick people Practice healthy behaviors Don t smoke, eat a healthy diet, exercise Use antiviral medication if prescribed
13 Novel H1N1 influenza: Background information
14 Preventing the flu Influenza Vaccine
15 Flu Vaccines Two types Trivalent inactivated influenza vaccine (TIV) (injectable) Live, attenuated influenza vaccine (LAIV) (nasal spray) Safety (known for seasonal vaccine) Shot: arm soreness, redness, swelling, low grade fever, mild muscle aches, fatigue Nasal spray: low grade fever, runny nose, headache, sore throat, fatigue DOES NOT CAUSE THE FLU!! Timing Protection takes at least 10 days
16 Flu Vaccines Seasonal vaccine Still important this year Available now Novel H1N1 vaccine First shipments anticipated ~mid-October Target and priority groups initially If available, everyone for whom medically appropriate may be vaccinated over the next 6 months Not mandatory
17 Who will get the H1N1 vaccine? Pregnant women Health care and emergency medical workers People who live with or care for children <6 months old Persons 6 months through 24 years Adults 24 through 64 years with high risk health conditions Pregnant women Health care workers with direct patient contact People who live with or care for children <6 months old Children 6 months through 4 years People 5 through 18 years with high risk health conditions Target Groups High Priority Groups CDC. MMWR Early Release. 2009;58 (August 21, 2009).
18 The Good News… Majority of those affected do not require hospitalization and recover without complications. So far, H1N1 flu appears similar to seasonal flu except for different high-risk groups. Antivirals still generally effective. Vaccine is developed, studies ongoing. Prevention measures work!
19 What else can you do? Stay home if you or your children are sick! Do not go to work, school or daycare until 24 hours after the fever has resolved Recovery takes 3-5 days for most people Healthcare workers: Stay home for 7 days after symptom onset or until S/S resolve Make a family plan Back-up plans for childcare Look into teleworking with your employer Food & water supplies Be flexible
20 H1N1 outbreak in Anne Arundel County Public Schools, Spring 2009
21 Spring 2009: Elementary School – 375 students and staff What occurred Whats going on simultaneously Family member ill (flu symptoms) Recently returned from Mexico Children home Children come to school School notified, etc Health Department directs school system Pandemic flu announced Media news bites clips focus on people wearing protective masks H1N1Vaccine not ready yet Worst is yet to come Anxiety - probably Panic – not yet but ….
22 School System Response School With Teachers and Admin. Facilities With Custodial Staff In consultation w/HD who, in turn, are following CDC: Family children sent home Meet w/teachers and staff Explain situation Advise cleaning protocols Promote good hygiene in classroom & home Letter sent home School will stay open School custodial staff backed up with extra volunteers to clean & disinfect classroom Provided training on virus, disinfection cleaning techniques, overview of disinfectant, and MSDS Provided gloves, masks, rags, spray bottles, pump sprayers Team cleaning approach Disinfectant sprayed on Wipe and rinse
23 Then what….. At schoolFacility Management Parents swamp phone lines Some kids stay home Rumors Many are sick Another child suspected of H1N1 School to close 5-7 days per H.D. News helicopters, TV reporters & cameras, etc. Gear up for full school disinfection; desks, chairs, hallways. Lockers, basically all surfaces, handles, sinks, knobs etc. TV Crews see inside school to see crews with masks, etc. National news show same scenario in a NY high school.
24 Swine Flu Spreads Across D.C. Region Washington Post A federal agent who traveled to Mexico with President Obama this month probably contracted swine flu and infected several members of his family in Anne Arundel County, prompting assurances yesterday from the White House that the President was safe. Parents and government officials are debating whether to close schools where suspected cases of swine flu have been discovered. What should officials do? Parents and government officials are debating whether to close schools where suspected cases of swine flu have been discovered. What should officials do? Keep schools open. Schools should be cleaned and sick children kept home, but closings go too far. 39% Close schools. School officials should take every step possible to protect children from the flu. 57% Other solution. Write your answer in the comments below. 2% Total Votes: 2,648
25 Community/parents alarm Folger McKinsey Elementary School in Anne Arundel County has a student that has been tested for the swine flu. The results have not come back yet. School and county officials were on hand for the opening of school Thursday morning.
27 Parents Debate Sending Children to School as Officials Urge Caution School National The word came so late in the school day yesterday that officials couldn't send a letter to parents, so they resorted to s and phone calls: A student at Folger McKinsey Elementary School in Severna Park was one of six probable cases of swine flu in Maryland. At a news conference last night, President Obama recommended that schools with suspected cases of swine flu strongly consider closing. But a spokesman for Gov. O'Malley said afterward that Maryland schools would remain open. "At this point it doesn't appear that it's necessary given the probable cases in Maryland," spokesman Shaun Adamec said.
28 CDC Guidance CDC School & Health Department On a national conference call, CDC states that any school with even a single case of H1N1 influenza should close for 5-7 days (possibly as long as 14 days). In conformity with CDC guidance, School and Health Department close school.
29 Outcomes SchoolFacilities Reopened in 3-4 days No outbreak School returns to routine Vast expenditure of manpower and equipment Lots of overtime
30 Lessons Learned from Spring 2009 Use of Incident Command System (ICS) Consistent, uniform messages from key leaders: Joint Information Center (JIC) Joint Press Conference Manage expectations; pro-actively stress need for flexibility in response to a dynamic situation. Frequent updates in understandable language: Public/parents/children: Phone bank Automated phone call-out system Websites Written materials (letters home, posters in schools) Staff (Schools, Health Department) Collaboration between Schools and Health Department: Planning (Schools/Health Department MOU; exercises) Implementation Communications (Continued)
31 Lessons Learned from Spring 2009 (continued) After-action analysis/assessment and follow-up action Needs identified: Formal school-based surveillance system School attendance policies Staff sick leave policies Identification of personnel and equipment shared between schools (e.g., buses and bus drivers, itinerant staff) Identification of, and planning for, higher-order effects of closure (e.g., free/subsidized meals, after-school activities, athletics) Tracking costs/expenditures Personal Protective Equipment (supplies, fit testing) Isolation rooms Handwashing stations
32 School response to Novel H1N1 Virus, Fall 2009
33 School response to Novel H1N1 Virus, Fall 2009: CDC Guidance--Philosophy Decision to dismiss students should: Be made locally Balance the goals of: Morbidity and mortality from influenza with Minimizing social disruption and safety risks to children sometimes associated with school dismissal. Based on the experience and knowledge gained in jurisdictions that had large outbreaks in spring 2009, the potential benefits of preemptively dismissing students are often outweighed by negative consequences, including: Students being left home alone Health workers missing shifts when they must stay home with their children Students missing meals, and Interruption of students education.
34 School response to Novel H1N1 Virus, Fall 2009: CDC Guidance Scalable Responses Recommendation: Stay home when sick Separate ill students and staff Hand hygiene and respiratory etiquette Conditions with similar severity as in Spring 2009: Facilities Issues: Location for screening upon return Instruction (study or teaching)while at home Isolation rooms (students, staff) Staffing Storage of masks (surgical masks for ill; N- 95s for healthcare personnel) Soap & towels, hand sanitizer, tissues: Supplies Locations, dispensers Refill, maintenance, security Waste receptacles (Continued)
35 School response to Novel H1N1 Virus, Fall 2009: CDC Guidance Scalable Responses Recommendation: Routine cleaning Early treatment of high-risk students and staff Consideration of selective school dismissal Conditions with similar severity as in Spring 2009: (continued) Facilities Issues: Supplies & equipment (gloves, masks, pump and hand sprayers) * Staffing Compliance with medication regimen Dispensing and storage of anti-viral Rxs Co-location of high-risk and normal-risk facilities * American Academy of Pediatrics Managing Infectious Diseases in Child Care and Schools: A Quick Reference Guide, 2 nd Edition (2009) for guidance on cleaning and sanitizing in schools.
