The answers
1. False. There is no such thing as stomach flu; flu is a respiratory illness, according to the CDC. Many people use the word "flu" for any infectious illness they get. In reality, flu is a specific type of infection, caused each year by ever-changing, ever-adapting strains of the influenza virus.
2. True. The vaccine is also recommended for children ages 6 to 59 months; people of any age with certain chronic medical conditions; people who live in nursing homes and other long-term care facilities; and women who will be in their second or third trimester of pregnancy during flu season. People with severe allergy to eggs shouldn't get the vaccine. A nasal spray vaccine is available for ages 2 to 49.
3. False. You cannot get the flu from a flu shot. The vaccine contains dead virus, explains the National Institute of Allergy and Infectious Diseases.
4. True. The antiviral medications oseltamivir and zanamivir fight flu if used within 48 hours after symptoms appear. Given within 36 hours of the first symptoms, these drugs can cut the duration of illness 30 percent and the severity of illness 40 percent. The CDC warns, however, that you shouldn't consider these drugs an alternative to vaccination: Few flu victims visit the doctor in time for the drugs to help.
5. False. You most often catch the flu by coming in contact with droplets of an infected person's cough or sneeze, the CDC says. Avoiding people you know are infected will cut your risk, as will frequent hand-washing. But by far, experts say, your best protection is the vaccine.
6. True. The Rapid Test takes about 30 minutes to an hour to show a result The older viral culture takes two to 10 days, past the time necessary for newer antiviral drugs to offer relief.
7. False. About 20,000 Americans die each year after becoming infected with the flu, according to the CDC. Nine out of 10 are older adults who develop complications such as pneumonia after they are severely weakened by flu.
8. True. The flu has more severe symptoms, with a fever, a non-productive cough, muscle ache, headache and fatigue. Generally, you feel like you've been run over by a truck. Most colds don't include fever or severe headache, muscle aches are milder, and fatigue and weakness from a cold are far less severe than from flu.
