Be cautious: its flu season

Influenza, aka flu, is a contagious viral infection that affects the respiratory system your nose, throat and lungs. Symptoms of the flu can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people may also have vomiting and diarrhea.

The flu can be an unpredictable and serious disease that can lead to hospitalization and sometimes even death.

The Centers for Disease Control and Prevention (CDC) estimates that from the 1976-1977 flu season to the 2006-2007 flu season, flu-associated deaths ranged from a low of about 3,000 to a high of about 49,000 people in a flu season.

While the flu can make anyone sick, certain people are at greater risk for serious flu-related complications, like pneumonia and bronchitis.

These groups include:
    Children younger than five, but especially children younger than two years old
    Adults 65 years of age and older
    Pregnant women
    American Indians and Alaskan Natives

And people who have medical conditions including:
    Asthma
    Neurological and neurodevelopmental conditions [including disorders of the brain, spinal cord, peripheral nerve, and muscle such as cerebral palsy, epilepsy (seizure disorders), stroke, intellectual disability (mental retardation), moderate to severe developmental delay, muscular dystrophy, or spinal cord injury].
    Chronic lung disease (such as chronic obstructive pulmonary disease [COPD] and cystic fibrosis)
    Heart disease (such as congenital heart disease, congestive heart failure and coronary artery disease)
    Blood disorders (such as sickle cell disease)
    Endocrine disorders (such as diabetes mellitus)
    Kidney disorders
    Liver disorders
    Metabolic disorders (such as inherited metabolic disorders and mitochondrial disorders)
    Weakened immune system due to disease or medication (such as people with HIV or AIDS, or cancer, or those on chronic steroids)
    People younger than 19 years of age who are receiving long-term aspirin therapy
    People who are morbidly obese (Body Mass Index (BMI) of 40 or greater.

The best defense against influenza and its possible complications is vaccination. The CDC recommends that everyone six months and older get an annual flu vaccination. The vaccinations are safe and cannot cause the flu.

Flu-Related Complications Can Affect You
Millions of Americans are impacted by long-term health conditions, but many people arent aware that they have one of these conditions. For example, diabetes affects about 26 million Americans, but it is estimated that one in four people with the disease dont even know they have it. Its important to ask your doctor whether you have a health condition that makes you more vulnerable to complications from the flu. In addition to those with chronic health conditions, many others are a high risk for flu complications because of their age or other factors.

Consider these facts:
During the 2012-2013 flu season, 45 percent of adults hospitalized with laboratory-confirmed influenza had heart disease.

Among Americans 20 years and older, 6.3 percent are morbidly obese (with a body mass index, or BMI, of 40 or greater).

In pregnant women, changes in the immune system, heart and lungs make them prone to more severe illness from flu. In addition, a flu-infected pregnant woman also has an increased chance for miscarriage or preterm birth.

In the United States, each year an average of 20,000 children younger than five years old are hospitalized because of flu complications.

During the 2012-2013 influenza season, 169 flu-related pediatric deaths were reported.

Among children six months and older, about 80-90 percent of flu-related pediatric deaths occur in children who have not received a flu vaccine.
    Nine out of 10 flu-related deaths in the United States occur in people 65 and older.

If you are currently living with a chronic health condition like heart disease, diabetes or asthma, certain behaviors are probably part of your daily routine, like watching your diet or glucose levels, taking your prescribed medications or keeping your inhaler on-hand. Make getting an annual flu vaccine another part of your health management routine its your best defense against the flu and related complications. Since the flu is contagious, its also important that all of your close contacts are vaccinated.

If you are at high risk for flu complications, be sure to ask your doctor about getting a pneumococcal vaccination, too. Pneumococcal vaccine can be given at any time during the year and may be given at the same time as influenza vaccine.

If you are sick with the flu early antiviral treatment is Important

If you have a high-risk condition and you get the flu, early treatment with flu antiviral medication is important. Antiviral drugs are prescription medications that can be used to treat the flu. Rapid treatment with antiviral drugs in someone with a high-risk condition can mean the difference between being sick at home and possibly ending up in the hospital. Studies show that these drugs work best when they are started within two days of getting sick. However, starting them later can still be helpful, especially if the sick person has a high-risk health condition or is very sick from the flu.

Antiviral medications are not a substitute for vaccination

Annual flu vaccination is the first and best way to prevent the flu, but if you do get sick with the flu, antiviral medications are a second line of defense to treat the flu.

Antiviral medicines can be prescribed by a doctor to help make flu illness milder and shorten the time you are sick. Data also show that antiviral drugs may prevent serious flu complications. If you have a high-risk medical condition and develop flu-like symptoms, check with your doctor promptly.
