You may think of the flu as pretty harmless. Most of the time, it is. People typically recover after about a week or two without any lasting problems. But sometimes, the flu can lead to serious complications requiring emergency care.
The CDC estimates that 200,000 people in the U.S. are hospitalized because of the flu every year. Thirty-six thousand die. Infants, the elderly, and people with certain diseases or weakened immune systems are the most vulnerable. But a flu emergency can happen to anyone. Since the flu can be dangerous, it's important to know the signs of trouble.
Person to Person
The main way that influenza viruses are thought to spread is from person to person in respiratory droplets of coughs and sneezes. (This is called "droplet spread.") This can happen when droplets from a cough or sneeze of an infected person are propelled through the air and deposited on the mouth or nose of people nearby. Influenza viruses may also be spread when a person touches respiratory droplets on another person or an object and then touches their own mouth or nose (or someone...
Different strains of the influenza virus cause the flu. You get the flu by either inhaling the germ or picking it up on your hands and then touching your eyes or mouth. Symptoms usually appear one to four days later.
The flu is sometimes hard to tell apart from a cold. But the flu usually comes on faster and is more severe. Also, keep in mind that a so-called "stomach flu" is not the same as influenza. The flu very rarely causes stomach or intestinal problems in adults.
Although flu vaccines can prevent certain strains of the flu, there's not much you can do after you get the flu. If taken within 48 hours of flu symptoms, drugs like Tamiflu and Relenza may lessen some of the symptoms. To ease flu symptoms, you can also:
Antibiotics will not help treat the flu. Antibiotics only work against bacteria. A virus - not a bacterium -- causes the flu. However, if you develop a secondary infection, or flu-related complication such as ear infections, sinusitis, or bronchitis, antibiotics may be needed.
Who's at Risk for a Flu Emergency?
Usually, you don't need to see the doctor if you get the flu. Your body will fight off the virus on its own with rest. But sometimes you -- or a family member -- may develop serious complications as a result of the flu. Those at increased risk of flu-related complications include:
Newborns and children up to age 5 (especially children under age 2)
