What to Do About the Flu
Each winter, millions of people suffer from the flu, a highly contagious infection. It spreads easily from person to person mainly when an infected person coughs or sneezes. Flu - the short name for influenza - is caused by viruses that infect the nose, throat, and lungs. It usually is a mild disease in healthy children, young adults, and middle-aged people. However, flu can be life threatening in older adults and in people of any age who have chronic illnesses such as diabetes or heart, lung, or kidney diseases
If you are a Medicare beneficiary and have received a phone call to participate in a survey of flu and pneumonia vaccine utilization and would like additional information you can visit the official project website http://www.flustudy.org/, send an e-mail to email@example.com, or call the toll-free hotline at 1-800-MEDICARE. HCFA appreciates the participation of the selected Medicare beneficiaries in this survey. The information these studies provide will help HCFA to better its efforts to improve the quality of the health care services provided to Medicare beneficiaries.
Can Flu Be Prevented?
A flu shot can greatly lower your chances of getting the flu. Much of the illness and death caused by flu can be prevented by a yearly flu shot.
The cost of the flu shot is covered by Medicare. Many private health insurance plans also pay for the flu shot. You can get a flu shot at your doctor's office. You also may be able to get a flu shot from your local health department or from other health care providers.
No vaccine gives complete protection, and the flu shot is no exception. In older people and those with certain chronic illnesses, the flu shot often is less effective in preventing flu than in reducing symptoms and the risk of serious illness and death. Studies have shown that the flu shot reduces hospitalization by about 70 % and death by about 85 % among older people who are not in nursing homes. Among nursing home residents, the flu shot reduces the risk of hospitalization by about 50%, the risk of pneumonia by about 60%, and the risk of death by 75 to 80%.
Who Should Get the Flu Shot?
According to the Federal Government's Centers for Disease Control and Prevention, the following people are at risk for serious illness from the flu and should get a flu shot every year:
When is the Best Time to Get the Flu Shot?
In the United States, flu season usually occurs from November until April. Most people get the flu between late December and early March. The best time to get your flu shot is between September and mid-November. It takes about 1 to 2 weeks after you get the shot to develop protection.
Does the Shot Cause Side Effects?
The flu shot does not cause side effects in most people. Fewer than one-third of those who get the shot have some soreness, redness, or swelling on the arm where the shot is given. These side effects, which can last up to 2 days, rarely interfere with a person's daily activities. About 5 to 10 % of people have mild side effects such as headache or low-grade fever for about a day after vaccination.
The flu shot is made from killed flu viruses, which cannot cause the flu. With very rare exceptions, the danger from getting flu - and possibly pneumonia - is far greater than the danger from the side effects of the shot.
One of these rare exceptions is people who have a severe allergy to eggs. The viruses for flu vaccines are grown in eggs and may cause serious reactions in people who are severely allergic to eggs. People who have a severe allergy to eggs should not get the flu shot.
Why Do You Need A Flu Shot Every Year?
Preventing flu is hard because flu viruses change all the time. This year's flu virus usually is slightly different from last year's virus. Every year the flu shot is updated to include the most current flu virus strains. That's one reason why flu shots will protect you for only 1 year.
What Are the Symptoms of the Flu?
Flu can cause fever, chills, dry cough, sore throat, runny or stuffy nose, as well as headache, muscle aches, and often extreme fatigue. Although nausea, vomiting, and diarrhea can sometimes accompany the flu, especially in children, gastrointestinal symptoms rarely occur. The illness that people call "stomach flu" is not influenza.
It's easy to confuse a common cold with the flu. Overall, cold symptoms are milder and don't last as long as the flu.
How Serious Is Flu?
Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and possibly life-threatening complications. While your body is busy fighting off the flu, you may be less able to resist a second infection. Older people and people with chronic illnesses run the greatest risk of getting secondary infections, especially pneumonia. In an average year, flu leads to about 20,000 deaths nationwide and many more hospitalizations.
How Is Flu Treated?
If you get the flu, rest in bed, drink plenty of fluids, and take medication such as aspirin or acetaminophen to relieve fever and discomfort.
Call your doctor if you have any signs of flu and:
Antibiotics are not effective against flu viruses. However, four drugs have been approved to treat people who get the flu:
When taken within 48 hours after the onset of illness, these drugs reduce the duration of fever and other symptoms. These drugs are only available by prescription.
