  • Influenza (the flu) is a respiratory infection.
  • It is caused by the influenza virus.
  • Influenza typically is spread by air or by direct contact from one person to another.
  • ...14 more annotations...
  • Influenza virus is very contagious.
  • Epidemics peak during the winter months
  • Most influenza cases occur during epidemics.
  • With influenza, the virus usually has mutated (changed) somewhat since the first infection.
  • The most common types of influenza virus are A and B. Influenza A is the one usually responsible for the annual epidemics.
  • Most people get multiple flu infections during their lives.
  • With many other types of infections, having the disease once protects against a second infection.
  • That is because the body's immune system remembers the returning virus. It attacks it immediately, and rapidly eliminates it.
  • A particularly widespread and severe epidemic is called a pandemic.
  • Flu can cause a variety of symptoms. They can be mild or severe. Symptoms and severity depend on the type of virus, your age and overall health.
  • Chills Moderate to high fever (101 to 103 degrees Fahrenheit) Sore throat Runny nose Muscle aches Headaches Fatigue Cough Diarrhea Dizziness
  • Vaccination — Vaccination can reduce your chances of getting the flu and transmitting it to others. Vaccination each year is recommended for everyone aged 6 months and older.
  • Good hygiene — The virus usually is passed through the air, by coughing. It also is passed by direct contact, such as shaking hands or kissing.
  • Antiviral drugs — Zanamivir (Relenza) and oseltamivir (Tamiflu) can substantially reduce your chance of getting the flu if they are taken just before an expected outbreak.

  • Influenza viruses are important pathogens that can cause sporadic respiratory diseases, annual epidemics and (in case of influenza A virus) periodic pandemics
  • Influenza researchers at five sites in the United States received funds from the American National Institute of Allergy and Infectious Diseases (NIAID) to collaborate with scientists worldwide in a network designed to advance understanding of influenza viruses – especially how they cause disease. The centers are based in Icahn School of Medicine at Mount Sinai (New York City), Emory University (Atlanta), St. Jude Children’s Research Hospital (Memphis), University of Rochester Medical Center (Rochester) and Johns Hopkins University (Baltimore).
  • Two classes of antiviral medications are currently used for the treatment of influenza, but each has limitations in scope and its effectiveness.
  • ...5 more annotations...
  • Antigenic diversity of the virus and constant influx of new subtypes allow the virus to become resistant to these antiviral drugs and evade vaccines. There is therefore a continuing need for new anti-influenza therapeutics using novel targets and creative strategies.
  • An aggressive immune response known as the cytokine storm plays an important role in causing significant tissue injury and mortality following human pathogenic influenza virus

  • most vaccine formulations for influenza are still produced by rather old-fashioned techniques that have been in use for over 60 years. Such methods involve the growth and passaging of the vaccine strains in embryonated chicken eggs, therefore production and subsequent formulation can take several months and rely

  • Preventing the flu
  • flu prevention is getting vaccinated each year with a flu shot
  • Avoid close contact with people who are sick, stay home when you are sick, cover your mouth and nose when you cough or sneeze, wash your hands, avoid touching your eyes, nose or mouth, get plenty of sleep, and drink plenty of fluids. In certain situations, antiviral drugs can be used to prevent seasonal influenza.

  • If you develop flu-like symptoms and are concerned about your illness, especially if you are at high risk for complications of the flu, you should consult your health care provider. Those at high risk for complications include people 65 years or older, people with chronic medical conditions, pregnant women, and young children.
  • Antiviral drugs may also be prescribed for treating the flu, depending upon the duration of illness, severity of symptoms, and your medical history.

  • Type A viruses are divided into subtypes or strains based on differences in two viral surface proteins called the hemagglutinin (H) and the neuraminidase (N)
