    In temperate climates, influenza A
    usually arrives between early winter and early spring. Influenza B can
    appear at any time of the year.
    The most common way to catch the flu is by breathing in droplets
    from coughs or sneezes. Less often, it is spread when you touch a
    surface such as a faucet handle or phone that has the virus on it, and
    then touch your own mouth, nose, or eyes.
    Symptoms appear 1 - 7 days later (usually within 2 - 3 days).
    Because the flu spreads through the air and is very contagious, it often
    strikes a community all at once, causing an epidemic illness. This
    creates a cluster of school and work absences. Many students become sick
    within 2 or 3 weeks of the flu's arrival in a school.
    Tens of millions of people in the United States get the flu each
    year. Most get better within a week or two, but thousands become sick
    enough to be hospitalized. About 36,000 people die each year from
    complications of the flu.
    Sometimes people confuse colds and flu, which share some of the
    same symptoms and typically occur at the same time of the year. However,
    the two diseases are very different. Most people get a cold several
    times each year, and the flu only once every few years.
    People often use the term "stomach flu" to describe a viral
    illness where vomiting or diarrhea is the main symptom. This is
    incorrect, as the stomach symptoms are not caused by the flu virus. Flu
    infections are primarily respiratory infections.

    The flu usually begins abruptly, with a
    between 102 and 106 °F. (An adult typically has a lower fever than a
    child.) The fever usually lasts for a day or two, but can last 5 days.
    Other common symptoms include:

    • Body aches
    • Chills
    • Dizziness
    • Flushed face

    • Lack of energy
    • Nausea
    • Vomiting

    Somewhere between day 2 and day 4 of the illness, the "whole body"
    symptoms begin to subside, and respiratory symptoms begin to increase.
    The most prominent of the respiratory symptoms is usually a dry,
    hacking .
    Most people also develop a and headache. Runny nose (nasal discharge) and sneezing are
    These symptoms (except the cough) usually disappear within 4 - 7
    days. Sometimes, the fever returns. The cough and tiredness usually last
    for weeks after the rest of the illness is over.
    Other symptoms may include:

    • Loss of appetite
    • and stiffness

    • Worsening of underlying illness, such as asthma or heart failure

    If you have mild illness and are not at high risk, take these steps:

    • Rest
    • Take medicines that relieve symptoms and help you rest
    • Drink plenty of liquids
    • Avoid aspirin (especially teens and children)
    • Avoid alcohol and tobacco
    • Avoid antibiotics (unless necessary for another illness)

    Most people who get seasonal flu will likely recover without
    needing medical care. Doctors, however, can prescribe antiviral drugs to
    treat people who become very sick with the flu or who are at high risk
    for flu complications. Ask your provider if you are high risk when you
    receive your flu immunization.
    The main benefit of antiviral drugs is that they can shorten the
    time you have symptoms by about one day, but only if you start taking
    the medicine within 48 hours of when your symptoms began.
    If you need treatment, the U.S. Centers for Disease Control and
    Prevention (CDC) recommend that your doctor give you zanamivir (Relenza)
    or osteltamivir (Tamiflu).
    Children who are at risk of developing a severe case of the flu
    should also contact their provider for antiviral medication.
