U.S. Department of Health and Human Services Secretary Michael Leavitt helped bring the affect of a pandemic home when he stated “Pandemics are global in nature, but their impact is local. When the next pandemic strikes, as it surely will, it is likely to touch the lives of every individual, family, and community.”

At a Pandemic Influenza Summit in Baltimore, Maryland, he stated “Any community that fails to prepare [for pandemic influenza] and expects the federal government will come to the rescue is tragically wrong.”

What is influenza or the flu?
Influenza or the flu is an acute viral infection of the respiratory tract caused by one of three strains of influenza virus – A, B, or C. Symptoms include fever, chills, body aches, headache, fatigue, dry cough, sore throat and congestion.

What is pandemic influenza?
Pandemic influenza is a global outbreak of influenza to which people have little or no immunity and for which there is no vaccine. The infection spreads easily, causes serious disease and can spread world wide very quickly. Symptoms can include diarrhea, nausea, and vomiting as well as normal flu symptoms.

There are three prerequisites for the start of an influenza pandemic:
1. A new influenza virus needs to be introduced to which humans have little or no immunity.
2. The new virus must be able to replicate in humans and cause disease.
3. The new virus must be able to efficiently transmit itself from one human to another.

There are about 3 pandemics each century. The three pandemics in the 20th century occurred in 1918-19, 1957-58, and 1968-69.

1968-69 34,000+ deaths in U.S.
  700,000+ deaths worldwide
1957-58 70,000+ deaths in U.S.
  1 to 2 million deaths worldwide
1918-19 675,000+ deaths in U.S.
  50 to 100 million deaths worldwide

The number of deaths depended more on the virulence of the virus than on treatments available. More Americans died of the flu in 1918-19 than died in WWI. In fact, more Americans died of the 1918 flu than died in all the wars in the 20th century.

There are some facts about vaccines that should be understood when discussing pandemic influenza.
• Vaccines are virus specific. They are only effective against one form of one virus.
• They protect but are not 100% effective.
• They do not cure influenza.
• Yearly flu vaccines are developed based on informed predictions of which flu strain will be most predominant that year.
• A pandemic virus is unknown until it infects and it will take at least six months to develop a vaccine against it.

Why should I be concerned about pandemic flu?
• There is no sure way to stop a pandemic from occurring.
• We cannot predict when the next flu pandemic will occur BUT the longest period between pandemics has been 42 years. The last one occurred in 1969.
• We cannot prepare a vaccine until the flu begins infecting people.
• We cannot prevent the spread of influenza without very exacting measures; it is very contagious.
• We cannot cure influenza.
• We cannot cure viral pneumonia, a possible secondary infection to flu.
• Bacterial pneumonia, another possible secondary infection, has a 20-30% death rate even with antibiotics.
• Flu symptoms may be more severe during a pandemic and the flu may have more complications.
• Even healthy people are at increased risk for serious complications during a flu pandemic.
• The number of deaths could be high.
• We know little more than they did in 1918 about how to cure the flu or how to prevent it. We only know how to lessen the impact IF those measures are implemented.

How will a pandemic affect me?
• 50% of the population could become infected.
• Work absenteeism is expected to be about 40% which could result in disruption of normal utilities, banking, businesses, etc.
• A pandemic could last 12 to 24 months.
• Communities could be affected by several waves lasting 3 to 8 weeks each.
• Vaccines and antiviral drugs will be in short supply and vaccines will not be available until at least the second wave of flu.
• Available healthcare will be limited because of high demand.
• You will probably be on your own or have limited assistance.

The current (2007) concern of health officials is the H5N1 avian influenza. It is a particularly virulent virus in birds, causing widespread death in flocks in a short period of time. It spreads from wild birds to domestic birds and can be transmitted to mammals. It has spread to humans who have had close contact with infected domesticated birds. It has met 2 of the 3 prerequisites for a pandemic to occur. Currently, it has not spread from human to human but that is the fear because it continues to evolve. If that were to happen, we would have a pandemic. Officials are trying to keep the virus from spreading by trying to eliminate it from chicken populations through mass slaughter and vaccines. The H5N1 appears to have similarities to the virus which caused the 1918-19 pandemic, so we can look to that pandemic to learn how to treat and prepare for the next pandemic.
