  • H1N1 flu is also known as swine flu. It's called swine flu because in the past, the people who caught it had direct contact with pigs.
  • In 2009, H1N1 was spreading fast around the world, so the World Health Organization called it a pandemic. Since then, people have continued to get sick from swine flu, but not as many.
  • Despite the name, you can't catch swine flu from eating bacon, ham, or any other pork product.

  • What is influenza (also called flu)?
  • The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccine each year.
  • Signs and symptoms of flu
  • ...58 more annotations...
  • People who have the flu often feel some or all of these signs and symptoms:
  • Fever*
  • though this is more common in children than adults.
  • It’s important to note that not everyone with flu will have a fever.
  • How flu spreads
  • Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk.
  • Period of contagiousness
  • You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.
  • How serious is the flu?
  • Flu is unpredictable and how severe it is can vary widely from one season to the next depending on many things, including:
  • Certain people are at greater risk for serious complications if they get the flu. This includes older people, young children, pregnant women and people with certain health conditions (such as asthma, diabetes, or heart disease).Flu seasons are unpredictable and can be severe. Over a period of 30 years, between 1976 and 2006, estimates of flu-associated deaths in the United States range from a low of about 3,000 to a high of about 49,000 people.
  • Complications of flu can include bacterial pneumonia, ear infections, sinus infections, dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.

  • Prevent seasonal flu: Get vaccinated
  • The single best way to prevent the flu is to get a flu vaccine each season. There are several flu vaccine options for the 2014-2015 flu season.Traditional flu vaccines made to protect against three different flu viruses (called “trivalent” vaccines) are available. In addition, flu vaccines made to protect against four different flu viruses (called “quadrivalent” vaccines) also are available.
  • Trivalent flu vaccine protects against two influenza A viruses (an H1N1 and an H3N2) and an influenza B virus.
  • While seasonal influenza outbreaks can happen as early as October, most of the time influenza activity peaks in January or later. Since it takes about two weeks after vaccination for antibodies to develop in the body that protect against influenza virus infection, it is best that people get vaccinated so they are protected before influenza begins spreading in their community.
  • When to get vaccinated against seasonal flu
  • Yearly flu vaccination should begin soon after flu vaccine is available, and ideally by October. However, getting vaccinated even later can be protective, as long as flu viruses are circulating.
  • The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It can cause mild to severe illness, and at times can lead to death.
  • Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.

  • Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick.

  • CDC does not know exactly how many people die from seasonal flu each year. There are several reasons for this. First, states are not required to report individual seasonal flu cases or deaths of people older than 18 years of age to CDC.
  • Second, seasonal influenza is infrequently listed on death certificates of people who die from flu-related complications
  • Third, many seasonal flu-related deaths occur one or two weeks after a person’s initial infection, either because the person may develop a secondary bacterial co-infection (such as bacterial pneumonia) or because seasonal influenza can aggravate an existing chronic illness (such as congestive heart failure or chronic obstructive pulmonary disease).
  • Also, most people who die from seasonal flu-related complications are not tested for flu, or they seek medical care later in their illness when seasonal influenza can no longer be detected from respiratory samples. Sensitive influenza tests are only likely to detect influenza if performed within a week after onset of illness.
  • In addition, some commonly used tests to diagnose influenza in clinical settings are not highly sensitive and can provide false negative results (i.e. they misdiagnose flu illness as not being flu.) For these reasons, many flu-related deaths may not be recorded on death certificates.

  • Age. Seasonal influenza tends to target young children and people over 65. The pandemic H1N1 virus that surfaced in 2009, however, appeared to be most common in teenagers and young adults. Occupation. Health care workers and child care personnel are more likely to have close contact with people infected with influenza. Living conditions. People who live in facilities along with many other residents, such as nursing homes or military barracks, are more likely to develop influenza. Weakened immune system. Cancer treatments, anti-rejection drugs, corticosteroids and HIV/AIDS can weaken your immune system. This can make it easier for you to catch influenza and may also increase your risk of developing complications. Chronic illnesses. Chronic conditions, such as asthma, diabetes or heart problems, may increase your risk of influenza complications. Pregnancy. Pregnant women are more likely to develop influenza complications, particularly in the second and third trimesters.
