Influenza A usually arrives in the late winter or 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. 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. Anyone at any age can have serious complications from the flu, but those at highest risk include: People over 50 Children between 6 months and 2 years Women more than 3 months pregnant during the flu season Anyone living in a long-term care facility Anyone with chronic heart, lung, or kidney conditions, diabetes, or weakened immune system Sometimes people confuse cold 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 several years.
