Facts About Influenza for Adults

    What is Influenza?

    Influenza (flu) may be a contagious virus infection primarily of the nose, throat, and lungs. Flu is caused only by the influenza virus, but many of us confuse illnesses caused by other viruses or bacteria, including severe colds (rhinovirus) or “the stomach flu” (norovirus and other viruses and bacteria) with influenza.

    Flu occurs mainly within the fall and winter months within the US and infects anywhere from 5-20 percent of the population annually. Flu seasons are unpredictable and may be severe. for instance, between 1976 and 2006, estimates of flu-associated deaths within the US ranged from a coffee of about 3,000 to a high of about 49,000 people. Unfortunately, there are no thanks to knowing beforehand whether anybody flu season is going to be mild or severe.

    Flu Symptoms

    Flu symptoms can include fever, aches, chills, tiredness, and sudden onset. Other symptoms may include cough, runny/stuffy nose, and /or pharyngitis. Unlike other common respiratory infections that are often called “the flu,” influenza can cause more severe illness which will end in complications resulting in hospitalization and death. However, whether symptoms are mild or severe, people can still spread the influenza virus to others. In fact, they will spread influenza-even before they show any symptoms.

    Flu Prevention

    An annual flu vaccine is that the best thanks to preventing influenza. The time to vaccinate is as soon as the vaccine becomes available, which may even be by late summer, and any time throughout the influenza season. Vaccination is required annually for the simplest protection because the vaccine is typically updated from one season to subsequent to guard against the influenza viruses that are presumably to circulate and immunity to influenza declines over time.

    Who Should Get Flu Vaccine? 

    Annual influenza vaccination is suggested for everybody age 6 months and older. For adults, meaning a vaccine annually. Pregnant women are specifically encouraged to urge vaccinated and should receive the vaccine any time during their pregnancy. The vaccine is out there in several forms:

    • The traditional injected vaccine includes inactivated (or killed) virus and is approved for everybody six months and older.
    • Nasal spray vaccine includes life, but weakened virus and is approved for healthy people age two through 49 years.
    • The intradermal vaccine that's injected into the skin instead of the muscle because it uses a smaller needle; includes inactivated (or killed) virus, and is approved for adults age 18 through 64 years, and should appeal to those that don't like needles.
    • The high-dose vaccine containing fourfold the quantity of antigen to induce a greater immune reaction in people 65 and older.

    Vaccine Safety 

    All types of influenza vaccines are safe and well-tolerated. The injected vaccines may end in some mild soreness, redness, or swelling at the injection site lasting one to 2 days. Other possible mild side effects include a headache and low-grade fever for each day after vaccination. The nasal spray vaccine may end in a runny nose, headache, low-grade fever, pharyngitis, fatigue or cough after vaccination. The potential risks related to influenza are much greater than the potential risks related to vaccination.

    Flu and Vaccine Facts

    • FACT: Influenza vaccines are safe and are the simplest thanks to helping prevent influenza.
    • FACT: Every adult within the US should get the influenza vaccine per annum.
    • FACT: Circulating influenza viruses change often, which affects how severe and the way common the illness is from year to year.
    • FACT: Flu seasons are unpredictable and may be severe. Between 1976 and 2006, estimates of flu-associated deaths within the US ranged from a coffee of about 3,000 to a high of about 49,000 people.
    • FACT: within the US, quite 200,000 individuals are hospitalized by influenza per annum, including 20,000 children.
    • FACT: Infants younger than six months cannot get the influenza vaccine, but they're high risk of great complications and hospitalization if they get the flu. the simplest thanks to protecting them are by vaccinating everyone around them.
    • FACT: The flu is caused only by the influenza virus. People often mistake other, less severe illnesses with influenza, just like the cold or the “stomach flu,” which isn't influenza in the least. Stomach illnesses are caused by other viruses, like norovirus, and lots of sorts of bacteria.
    • FACT: Total direct hospitalization costs of a severe influenza epidemic are estimated to be over $6 billion.
    • FACT: Influenza vaccine is required per annum because the immunity wears off over time and also because in most years the vaccine is updated to match circulating strains.
    • FACT: Influenza can make chronic conditions worse. It is often related to heart attacks, make it harder for diabetics to regulate their sugar levels, make asthma worse, and cause pneumonia.
