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

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
