What should the public know about pandemic influenza now?

Pandemic influenza is a global outbreak caused by a new influenza virus.
• The virus may spread easily, possibly causing serious illness and death.
• Because so many people are at risk, serious consequences are possible.
• Historically, pandemic influenza has caused widespread harm.

Scientists are confident that an outbreak of pandemic influenza will occur again.
• There have been three influenza pandemics in the last century, including an outbreak in 1918 that killed tens of millions of people worldwide.
• Scientists are uncertain when a new pandemic will occur and how severe it may be.
• Influenza viruses are always changing: new influenza viruses emerge or old ones re-emerge that can spread easily.

Preparing now can limit the effects of pandemic influenza.
• The World Health Organization, the US Department of Health and Human Services, and countries throughout the world are building on existing disease outbreak plans, including those developed for SARS.
• A coordinated international effort is underway to develop vaccines and improve the detection and tracking of influenza viruses.
• Individuals should stay informed about pandemic influenza and prepare as they would for any emergency.
