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.
This document updates previously posted information for parents about infant
feeding and novel H1N1 flu (swine flu). It now more clearly addresses
parents who are formula feeding as well as breastfeeding, suggests that parents
sick with novel H1N1 flu (swine flu) find someone who is not sick to feed the
baby, and provides more detailed strategies for breastfeeding mothers to
maintain breastfeeding throughout the course of infection. This document is
based on current knowledge of the novel...
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.
Normal flu symptoms include:
Tiredness (can be extreme)
Runny or stuffy nose
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:
Take over-the-counter painkillers like Advil, Motrin, and Tylenol to relieve body aches and headache and control fever.
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)
People over 65
People who live in long-term care facilities
Caregivers of children or the ill
People with chronic diseases such as asthma, neuromuscular disease, heart problems, or lung disease
People who have depressed immune systems, either from disease or its treatment
