As winter approaches each year we brace for flu season. This year brings an extra complication: the H1N1 virus, also known as swine flu. In June, the World Health Organization declared H1N1 a pandemic. Since then, the media has brimmed with H1N1 stories, governments have stockpiled Tamiflu, flu vaccines have been developed, temperature sensors have been installed in Asian airports, and gallons of hand sanitizer have been dispensed. 

While the concerns are justified, we have always been vulnerable to various forms of the flu (influenza) virus. Flu viruses continually undergo genetic modification, presenting our immune systems with new challenges each season. To help you make sense of what’s in the news and plan your own best course of action, here’s a quick look at what you need to know about H1N1 and seasonal flu, and how to stay healthy.

H1N1 and Factory Farms                                   

Big changes can happen when influenza viruses jump species. Birds, humans and pigs each have their own viruses that circulate among their populations. Pigs, however, can become infected with avian, swine and human viruses. Viruses can trade genes, potentially creating a novel virus capable of infecting humans, such as H1N1. Some authorities have tied industrial-scale hog farms — where animals are crowded together — with the origin and spread of the H1N1 virus.

How Flu Viruses Spread

Influenza viruses are very contagious. Sneezes and coughs propel the viral droplets into the air, and an infected person begins shedding viruses a day before symptoms strike, thus thwarting quarantines from being a completely effective tactic. These viruses can survive on inanimate objects for two to eight hours. You touch that object (a borrowed pen, a shopping cart), then rub your eye, nose or lips — and presto, inoculation.

Recognizing Flu Symptoms

One to three days after exposure, flu symptoms develop: fatigue, fever, body aches, headache, sore throat, cough, and even vomiting or diarrhea. Children may also develop middle ear infections. People with respiratory ailments, such as asthma and chronic obstructive pulmonary disease, are especially vulnerable to complications such as pneumonia. 

Who Gets the Flu?

Whereas the seasonal flu or influenza viruses take a greater toll on the very young and the very old, the H1N1 virus (swine flu) has so far proved most dangerous to children and young adults.  So far, most of the deaths have been of people with other significant health problems, and the vast majority of the million or so H1N1 flu cases have been mild, on par with seasonal influenza. 

Vaccines for Seasonal Flu and H1N1

The vaccine for this season’s expected influenza viruses, though recommended to protect against these viruses, doesn’t work against the H1N1 virus. The Centers for Disease Control (CDC) anticipates a vaccine against the novel H1N1 will be available this fall. The CDC’s Advisory Committee on Immunization Practices has prioritized the H1N1 vaccine for groups at higher risk of complications: people who work in the health care industry, live with or care for babies younger than 6 months old, are pregnant, are between the age of 6 months to 24 years old, or are 25 through 64 years old with chronic illnesses or immune dysfunction. 

Seasonal and H1N1 Flu Prevention Tips

Basic hygiene measures can prevent the flu’s spread.

  • Wash your hands (and your small children’s hands) frequently with soap and water or use an alcohol-based cleaner.
  • Sneeze or cough into a tissue or your elbow.
  • If you or your child falls ill, stay home. The contagious period stretches from one day before symptoms strike to five to seven days thereafter. The CDC recommends people stay home until they’re without fever for 24 hours.

Natural Flu Prevention and Remedies

Healthy lifestyle choices can keep your immune system in fighting shape. Sleep deprivation, stress, smoking, malnutrition and alcohol excess all undermine immunity. Conversely, a healthy diet, adequate sleep, regular exercise and relaxation improve immune health.

Some herbs have antiviral activity, including against some influenza strains. The list includes ginger, licorice and garlic (use it raw in food). Two small studies have shown that a proprietary elderberry syrup (Sambucol) shortens the duration and severity of influenza.

Immune-enhancing herbs such as ginseng and eleuthero (Siberian ginseng) have been shown to help prevent viral respiratory infections, including the flu. One study found that giving ginseng a few days before the flu vaccine boosted the subsequent immune response. The Chinese herb astragalus also acts as an immune tonic. Taken in adequate dosages, echinacea and andrographis have both been shown to curtail upper respiratory infections. Whether any of these herbs can help counter H1N1 flu is unknown.

Vitamin D and the Flu

Vitamin D plays a role in many bodily processes, including immune function. Some scientists have pointed to a correlation between wintertime troughs in vitamin D intake and respiratory viral infections. New research published this year in the Archives of Internal Medicine linked low blood levels of vitamin D with a heightened risk of upper respiratory infections, particularly among people with chronic lung conditions. No studies have yet determined whether supplementing with vitamin D can prevent the common cold, much less influenza. Because few foods provide vitamin D, many experts recommend supplementation with at least 1,000 IU a day of vitamin D — several times the current guidelines for 200 to 600 IU.

Antiviral Medications and the Flu

The antiviral medications Tamiflu (oseltamivir), which is derived from Chinese star anise, and Relenza (zanamivir) may make flu symptoms milder.  Most experts recommend these medications be reserved to prevent disease in people at high risk for complications (in the face of suspected exposure) and to treat people who develop severe flu symptoms. (Overuse of these medications can lead to viruses becoming resistant to their effects.)

Anyone under the age of 18 should avoid aspirin, which, when taken during a viral illness, can lead to a serious condition called Reye’s syndrome, a rare disease characterized by neurological disorders, brain swelling and enlargement of the liver.

When to Get Medical Treatment for the Flu

Seek medical attention if you develop signs of severe illness: shortness of breath or difficulty breathing, chest or abdominal pain, dizziness, confusion, or severe vomiting. Signs that a child needs immediate care include rapid breathing, poor fluid intake, extreme irritability and lethargy (the child is difficult to wake and won’t interact).

I read a quantified study on PubMed this week where elderberry (sambucus nigra) was shown to inactivate H1N1 in vitro. My family has never had a flu shot - despite on immune deficient member - and never had the flu. We are taking two doses of homemade elderberry tincture (using sambucus nigra but I do believe sambucus canadensis would work the same way) twice per day in hopes of preventing this. In the end, none of us knows what will result from our choices - but at least we all investigate all our options before filing into line like drones.

Vaccines work! Currently at my children's grammer school, more than 75% are out with the flu. My kids remain healthy because they got vaccinated earlier this fall. When I was a kid (back in the 60s/70s)they would line us up in the gym and we would all get whatever shot was needed. Mass vaccinations ended small pox and mumps for generations. When was the last time anyone broke out with small pox? Mumps is pretty rare too. Unlike me, my kids have never even gotten chicken pox! So, please everybody, end the mass hysteria about vaccines. Medicine is good. The Feds are NOT out to experiment on you or anything like that. Let's leave those scenarios to Sci Fi movies where they belong. Other good ways of staying healthy are DON'T BE FAT, seriously being fat is not good. Eat more organic food and less junk/fast/convenience food. Don't smoke or drink. Those tips alone will improve your health, your disposition and your appearance.

This is a great article! So far, the H1N1 flu is milder than the normal seasonal flu. People who die of the flu are usually unhealthy. So, keep healthy by eating fresh food (vegetables, vegetable, vegetables!), exercise a bit and get enough sleep. And end every hot shower with a short cold one to boost your immune system (contraindication: uncontrolled high blood pressure and arterial disease)! Alexa Fleckenstein M.D., physician, author.

Eat elderberries whole and dried,as will be out of season, drink colloidal silver,bathe in a 3% solution of hydrogen peroxide(this goes into the bloodstream and kills virus'), drink a tall glass of water with one tablespoon of baking soda. Don't take the vaccine if you want to get better. The vaccine has been produced by Big Pharma,elite owned companies Baxter International ,Novartis and GlaxoSmithKline. Baxter was the company caught in February this year tampering with the aids virus and sending it to Europe as a vaccine when they knew it was infected with hepatitis B. The swine flu is a scam flu. No pigs have been infected. Do your research over the internet,look at David Icke,You Tube,do not fall for this mass vaccination attempt on a global scale to reduce the population and give the pharmaceutical cartel even more power and control. They are saying that people dying of seasonal flu and pneumonia are dying of swine flu, they are filling 'call centres' with 16 yr olds untrained and unqualified and accepting phone diagnosis. They want everyone queuing up at the innoculation booth. Vaccinations produce ailments and permanent sickness in populations,there is no such thing as a good vaccination.
