Threat of Pandemic InfluenzaThreat of Pandemic Influenza

• Circulating in wild birds, poultry and pigs

Animal Influenza

• Infects humans in rare instances - resulting from close exposure to pigs

• If virus evolves into a human virus it could cause a human influenza pandemic

Pandemic requirements Pandemic requirements

Global outbreak of disease

Appearance of flu virus A with pandemic potential

It causes sustained human-to-human transmission

Population has no or limited immunity

Broad Risks of a PandemicBroad Risks of a Pandemic

• Food and income loss from poultry deaths/ culling & decreased economic activity

• High illness & potentially higher death rates• Overstretched health facilities• Disproportionate impact on vulnerable

• Increased demand for governance & security• Higher public anxiety• Reduced capacity due to illness & death

• Deterioration of coping & support mechanisms• Interruption in public services• Quarantine policies• Trade & commerce disruptions• Degraded labour force• Interruption of regular supply systems

Pandemic PhasesPandemic Phases

6 |

Phase 5Phase 5

Phase 5 is characterized by the same identified virus causing sustained community level outbreaks in at least 2 countries in 1 WHO region.

Most countries won't be affected at this stage

Declaration of Phase 5 signals a pandemic could be imminent

Time to finalize organization, communication, implementation of planned mitigation measures is short.

7 |

Phase 6Phase 6

Phase 6 is characterized by community level outbreaks of the same virus in at least 1 other country in a different WHO region.

Designation of this phase would indicate that a global pandemic is under way.

IHR in WHA 62IHR in WHA 62

• WHA decision on annual reporting on implementation IHR• Yearly questionnaire, Feb 2009. 82 States parties reported • Evidence of more cross sectoral coordination

• On line training, surveillance capacity building Lyon Office• Strengthening laboratory quality and bio-safety• Strengthening of National Influenza Centres (NIC)• Relations with other UN agencies, ports and airports authorities• 684 events reviewed (June 2007-dec 2008). 19% reported

through National Focal Points. 7% Risk assessment tool was used. Further research needed
