Flu Facts
What is a pandemic?
A pandemic is an outbreak of disease that affects many people at the same time in many parts of the world.
What is "the flu?"
The flu (Influenza) is a highly contagious viral infection that begins in the respiratory tract. It can lead to serious complications including pneumonia or even death. There are three types of influenza viruses: A, B, and C. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. The emergence of a new and very different influenza virus to infect people can cause an influenza pandemic. Current influenza A viruses found in people are influenza A (H1N1) and influenza A (H3N2). In the spring of 2009 a new influenza A (H1N1) virus emerged to cause illness in people.This virus was very different from regular human influenza A (H1N1) virus and the new virus has caused an influenza pandemic.
Seasonal flu?
- A common disease people get each year. It causes cough, fever, and body aches.
- Usually not severe and most people recover on their own.
- Most serious risk to the very young or old, or those with other serious or chronic medical problems.
- People usually have some immunity to it from having had flu before or from having received flu shots in the past which have given them some immunity.
- An estimated 36,000 people in the U.S. die from flu in an average flu season.
Why is this flu sometimes called the "Swine Flu"?
This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs (swine) in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and bird (avian) genes and human genes. Scientists call this a "quadruple reassortant" virus.Is a disease in humans. Pandemics can range from mild to severe.
Has a flu pandemic ever happened before?
Yes. There have been outbreaks of pandemic flu in the past and there will likely be more in the future. In the past century there were three flu pandemics. In 1918 the "Spanish Influenza" killed more than 500,000 people in the United States and, according to some estimates, 50 million people worldwide. In 1957-58 the Asian flu caused approximately 68,000 deaths in the United States, and in 1968-69, the Hong Kong flu caused up to 34,000 deaths in the United States.
Can scientists predict when the next pandemic flu will happen?
No.
Is Pandemic Flu like the flu that happens every year?
The flu that happens every year is seasonal flu. Some of the symptoms of seasonal flu might be present in a pandemic flu. But a severe pandemic flu can very rapidly cause complications in healthy people that are far more serious than seasonal flu complications.
Will pandemic flu arrive overnight, without warning?
Chances are we will be aware of the presence of a pandemic flu before it arrives in the tri-counites. Scientists worldwide are closely watching various viruses and will likely know if and when easy human to human transmission is first observed. But, once pandemic flu has started, it will spread very rapidly among people. International travel is common and someone carrying a highly infective flu might infect others as they travel, before they even know they have the flu themselves. Pandemic flu could arrive in the United States from another country in just the time it takes for an overseas flight. This is why it is best to be informed and take steps to be prepared NOW, before a pandemic occurs.
What happens when a pandemic hits a community?
Because of the highly infective nature of a pandemic flu virus, many people in a community would be ill in a very short period of time. The illness hits hard and spreads quickly. Some people may wake up feeling fine and be bedridden by noon. Those who are sick would be physically unable to perform their usual daily tasks.
An outbreak could affect critical community functions very quickly. With people becoming ill or needing to care for family members who are ill, absenteeism could be high and businesses and government would be hard-pressed to conduct business as usual. Hospitals could fill up quickly, yet health care workers would be among the ill so staffing would be low. Transportation and interstate commerce could be slowed causing shortages of food and supplies. These things can also happen in the event of other widespread illness, or as a result of natural or man-made disasters.
These possible outcomes could be made less devastating if individuals and communities are prepared.
