What is the Influenza A (H1N1) Virus? 2 H1N1 is a completely new strain of influenza or “flu” virus Genetic material from pig, bird and human combined to form this new strain Can spread from person-to-person through coughing or sneezing of ill persons Despite term “swine flu”: Infections not associated with contact with pigs or pork meat
So What? 3 This new influenza virus has already sparked a pandemic A pandemic is world-wide epidemic Results from emergence of a new virus in which overall population has that no immunity Severity can vary
Past Influenza Pandemics 1900 1850 1950 2000 1847 1889 1918 1957 1968 42 yrs 29 yrs 39 yrs 11 yrs Pandemic usually occur every 30 – 40 years Last Pandemic was ≈ 40 yrs ago, in 1968....
“Phase 6, the pandemic phase, is characterized by community level outbreaks in at least one other country in a different WHO region in addition to the criteria defined in Phase 5. Designation of this phase will indicate that a global pandemic is under way.” - WHO WHO Pandemic Phase 6
What We Know About Pandemics More than one pandemic wave likely Can be weeks or months between waves Severity of waves unpredictable: subsequent wave could be worse than first Typically affects young, healthy adults (unlike regular seasonal flu)
Why Must the UN Prepare? A severe pandemic can have great impact on the organization Social disruption due to fear and panic in community Routine life may be affected High absenteeism everywhere – staff focus on own families’ health 8 In March 2006, the Secretary-General directed all UN offices to prepare for a pandemic
But We Don’t Act Alone…. The UN works closely with the national, state and city health and emergency authorities Some of the public health responses by host country/city authorities may include: –Distribution of medical supplies –Some restrictions on transportation –School/child care closures –Cancelling of public gatherings –Isolation / quarantine of persons at home 9
1. Practice Personal Hygiene Wash hands oftenCover coughs and sneezes 11
Value of Proper Handwashing Unwashed hand Washed hand
2. Practice Social Distancing Avoid close contact will ill persons Stay home if ill 13
3. Heed Travel Advice No Travel Restrictions –Seek medical care if you feel sick during travel –After return from travel, monitor your health for 7 days Practice personal hygiene Wash hands and cover coughs and sneezes 14
4. Have Self Care Knowledge Know how to care for yourself or others at home Know the symptoms of mild and severe influenza 15
Similar to regular seasonal flu symptoms Fever (often >101 o F), chills, dry cough, sore throat, body aches, headache, extreme tiredness, runny nose/nasal congestion For H1N1, may get nausea, vomiting, diarrhea What Are the Symptoms of Flu?
Current outbreak: Majority of mild cases recovered without any treatment Current recommendation: –If no underlying conditions: Rest at home –If at higher risk of severe disease: See a doctor People at higher risk of severe disease: –Those > 65 years, or < 2 years of age –Anyone with lung, heart, kidney, liver or blood disorders, or diabetes –Anyone with a weak immune system, possibly due to illness or medication –Pregnant women –Those on long-term aspirin therapy. What Should I Do If I have Mild Symptoms?

Search for and contact a local health care provider near where you live: Use network of participating physicians under your health insurance plan to identify your doctor (http://www.un.org/Depts/oppba/accounts/i nsurance/healthPlans.htm ).http://www.un.org/Depts/oppba/accounts/i nsurance/healthPlans.htm Getting Prepared: Choosing A Local Health Care Provider
Antiviral Medication (e.g. oseltamivir) 23 Can reduce severe symptoms of flu Currently not recommended for mild illness, unless are at “higher risk” of severe symptoms UN has stockpiled an amount Due to limited medical resources in the UN Medical Services, staff should contact your local health provider for first line health services
When To Use A Surgical Mask? 24 WHO: No evidence that wearing masks in community setting is effective Currently recommended only for ill persons and in health care settings and medical staff caring for suspected patients Nevertheless, individuals may wish to wear it – but must remember it should be combined with other public health measures
