A person infected with flu virus may be contagious:

  • 24 hours before showing symptoms
  • Up to 7 days after onset of symptoms, and sometimes even a bit longer.

Young children and seniors can be contagious for up to 14 days following onset of symptoms.

If you have the flu, avoid direct contact as much as possible with people most at risk of complications. This way, you reduce the risk of transmitting the illness to them.

The best way to protect yourself from complications of the flu is through vaccination.

Where to get Vaccinated
For information on the Flu Vaccination Campaign for each region of Québec, see the Where to get vaccinated section.

Certain protection and cleanliness measures can also help prevent transmission of the flu.

  • Wash your hands often
  • Keep your immediate environment clean, such as furniture surfaces and counters
  • Follow advice for Preventing Transmission of Viruses and Bacteria
  • Stay at home as soon as you notice symptoms of the flu. Unless otherwise advised by a doctor, home is the best place for treatment. By staying at home, you limit contact with other people or with other infections that may cause complications. You also limit transmission of the virus
  • Follow advice for Coughing or Sneezing Without Contaminating

The vaccine requires two doses, 2 to 4 weeks apart, followed by re vaccination. Often dogs that are vaccinated for kennel cough are vaccinated for canine influenza as well. Most dog shelters and veterinarians offer the vaccine a low cost ($35 to $45).

The dog flu vaccine is a killed viral vaccine, so there is no potential for the vaccine to cause the virus itself. It is save for dogs 6 weeks of age or older. Like other dog influenza vaccines, it may not prevent infection of the dog, but will reduce the severity of the clinical disease, it will reduce the progression of the disease to pneumonia, and reduce the time that a dog can spread the disease to other dogs.

Treatments for both the conditions involve preventing the body from getting dehydrated. Administer plenty of fluids and take rest. Medications usually aim to treat the symptoms, although diarrhoea is a natural defensive mechanism for the body to eliminate the bacteria. The risk of dehydration should be reduced.

Diagnosis

The diagnosis is difficult and doctors will usually prefer to conduct further microbiological tests for confirmation only in severe cases. The best way to find the possible reason as food poisoning is to observe the occurrence of similar symptoms in people who have consumed the same food sample

The terms are misunderstood since the symptoms do not differ much. In either case, the body’s immune responses fight in the same way. Hence the same sort of medicines will help in treatment. However since the severity can never be predicted it is wise to get the proper medical care without delay. If the symptoms get severe, then it is better to narrow down to the causative agent and administers drugs targeted for the microbe. Taking plenty of fluids may help most patients to recover within 24 hours but the fatigue may prevail for a couple of days. Fortified food and drinks which supply nutrition are extremely good to keep the body well hydrated.

Flu symptoms with neck and back pain and muscles aches can have several different causes. Learn more about what these symptoms could mean.

While these symptoms may just be a case of seasonal influenza, it can also be caused by other illnesses. Isolating some of the possible problems requires knowing more about the causes of the flu-like symptoms.

Cat scratch disease spread to humans through the cat’s claws. The disease is caused by a bacteria, Bartonella henselae. Cat scratch disease begins with mild flu-like symptoms, such as fever and fatigue. Neck pain occurs due to lymph node swelling. Muscle aches and back pain are part of the overall malaise caused as the body fights the bacteria. Doctors identify cat scratch disease through a special test to identify the bacteria. A lymph node biopsy helps with diagnosis.

West Nile virus has been in the United Stated since 1999. Mosquitoes transfer the virus to people after biting infected birds. Once infected, the person shows symptoms similar to the flu, such as headache, nausea, sore throat and a lack of appetite. Other symptoms of West Nile virus include back pain, muscle aches and a stiff neck. Usually the symptoms last for no more than a week, though in some people meningitis may occur. The virus can be identified through antibodies present in blood tests.

Spread by ticks, Lyme disease can cause flu symptoms with neck and back pain and muscle aches. It begins with a rash near the tick bite site. The infected person will develop symptoms such as swollen lymph nodes, headaches and fever. The person may experience back pain due to chronic arthritis caused by the disease, along with a stiff neck. Doctors diagnose Lyme disease with a blood test and treat it with antibiotics.

Swine flu, or H1N1, is a type of influenza, but the symptoms may be more severe than the typical seasonal flu. Symptoms of swine flu include muscle aches, joint pain and tender lymph nodes, all of which can cause neck and back pain. General flu symptoms such as a sore throat are also present. Individuals with medical conditions, like diabetes, asthma or cancer, can become very ill from swine flu. Medical professionals can test for H1N1 and treat it with antiviral medications.

Any time you experience flu-like symptoms, along with more severe symptoms like neck pain, you should seek medical care. Tests can isolate what causes the symptoms and what treatment path to take. Waiting to get treatment can cause long-lasting problems in some cases.

Learn how to identify your headache. Is it part of your head cold symptoms or something else?

Along with other common cold or flu symptoms — runny and stuffy nose, sore throat, cough, chills, and fever — you may have a headache. In a clinical trial that evaluated patients with upper airway cold symptoms, more than 60 percent experienced headache as part of their head cold.

D.C.: Is is safe to travel to Central America?

Richard Wenzel: I have not heard of any reports of influenza in Central America, but it is likely that some cases will come to light in the next few weeks. CDC will suggest postponing non-essential travel to Mexico today. So the best advise is to stay alert to their travel advisories.

Fredericksburg, Va.: What is the possibility of EU countries closing borders to international travel from the United States?

Richard Wenzel: Whenever there are risks of transmission of new infections from one country to another, there is always some risk that travel restrictions will result. We saw that with SARS and could see that with swine flu if the numbers and severity increase in the US.

Cleveland, Ohio: The case of swine flu in Ohio occurred in Elyria, which is very close to Cleveland. Is it possible that Tamiflu will be made available for people in our area to take now as a precautionary measure? You mentioned that people who have been "exposed" to the virus should take it, but how does one know if one has in fact been exposed?

Richard Wenzel: This is a difficult question. The exposures that qualify for prophylaxis include those within families or those with prolonged exposure such as that of a school. Unless the outbreak is wide spread, general prophylaxis is not indicated.

State College, Pa.: Why is this virus receiving such rapid, mass attention when there are so many viruses passed around all the time?

Richard Wenzel: This is a new virus not seen before, it may have caused 100 deaths in Mexico, and it has been quickly identified in countries on three continents. Influenza is more than a common cold with respect to its ability to harm patients. These are some of the reasons for the attention given to the new virus.

Washington, D.C.: I'm having a little trouble reconciling the president's "there no immediate danger" comments as well as the Post's Check-up blog that basically says "chill out folks" with your comments suggesting everything from face masks to foregoing handshakes to consternation that the threat level has not been elevated. Which is it?

Richard Wenzel: This is a serious problem and now is the time to prepare for all contingencies. We need to be extra cautious until we know the extent of transmission and of the virulence of the virus. It is also a time for scenario playing, i.e. the what ifs: Communication, drug supply and delivery, infection control recommendations for hospitals, development of hot lines that might be needed etc. In summary, this is the time for special precautions, but not panic or alarm.

Penn Quarter, D.C.: Is this the same swine flu that was around in the mid 1970s? Will the shot I got then help me now?

Richard Wenzel: Unfortunately this is different virus, and it is unlikely that you are protected, but I have not seen specific antibody analyses yet.

Virginia Beach, Va.: Are there any special precautions or drugs that my son should take as a patient currently undergoing chemotherapy, hence with a very compromised immune system?

Richard Wenzel: At this point, I would not recommend prophylaxis. However, if the epidemic spreads to your city, it may be prudent to offer prophylaxis for a period of time. You should consult with his oncologist about the timing for such an approach.

20002: Can this virus be spread through the air? Or does you have to touch something that has the virus on it and then touch your mouth, nose, etc.

Flu season killing record number of older Americans, CDC says

Jump to text This year’s especially grim flu season has been sickening and killing a very high.
Next story in Cold and flu Zinc may shorten the common cold

>>> some good news tonight about the nasty flu season we've been enduring in this country. cdc says flu activity is down. we have probably, probably seen the worst of the season. flu activity was listed as widespread this week. 38 states at least down from 42 states last week. news remains bad for the elderly, however, with more than 50% of hospitalizations in patients over

This year’s especially grim flu season has been sickening and killing a very high number of people over 65, federal officials report -- even people who consider themselves relatively healthy and not frail.

Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

The latest flu statistics show that while the season is leveling off, it’s still a bad one for seniors.

“The numbers for hospitalizations are extremely high in the elderly. In fact, they are the highest we have had since surveillance began in 2005,” says Dr. Lyn Finelli, a flu expert at the Centers for Disease Control and Prevention. “The deaths are way over the epidemic threshold. We are very concerned about the elderly this year", she added in a telephone interview.

“The elderly rates are many, many times the rates in other age groups.”

Flu statistics show the virus is still widespread in 38 states. Nine percent of reported deaths were due to flu and pneumonia, still above what’s considered an epidemic. And 14 more children died of flu last week, bringing the total this year to 59.

It’s still especially bad in the midwest and west, although infections are beginning to wane in the east. Dr. Jeff Duchin, an epidemiologist and flu expert at the University of Washington in Seattle, says he’s seen the impact.

“We have had a record in long term-care facility outbreaks this year,” Duchin, who is also a spokesman for the Infectious Diseases Society of America, said in a telephone interview.

“County emergency department reports are showing us higher prevalence of disease among older folks compared to what we had seen in recent years.”

CDC said people over 65 need to make sure they see a doctor right away if they get flu-like symptoms. That’s because quick treatment with antivirals can help prevent serious illness.

“We see unnecessary delays in treatment, particularly in the elderly,” Duchin said. “We need to recognize these cases promptly so the medications can be started promptly.”

Antiviral drugs such as Tamiflu only work well when given within a day or two of symptoms starting.

People 65 and older may not consider themselves at higher risk, Finelli says. But they need to: Their immune systems are less robust from those of younger people and they are still more vulnerable.

“Even if they are super-fit maybe they have other underlying conditions that put them at higher risk for the flu, like pulmonary (lung) disease and cardiovascular disease and diabetes,” Finelli said.

A study published earlier this week showed that people over 65 have different types of antibodies from younger people. These immune system proteins recognize and attack invaders like germs and they are stimulated by vaccines.

They’re warning people in some central Kentucky counties about a fast-spreading stomach virus.

This winter's cold weather is keeping people inside and in close quarters which is allowing sicknesses, like the norovirus, to spread easily.

“We have had a lot of reports of illness in the community and the schools of G.I. symptoms like diarrhea, vomiting and fever,” said Pam Spradling, the Director of Administrative Services at the Montgomery County Health Department.

Spradling says the county hasn't had any confirmed norovirus cases yet.

But she says it is common for people to think they have the flu when they actually have norovirus.

“A lot of the times we hear people call norovirus the stomach flu which isn't true. It is not the flu. The flu is influenza and a completely different virus.”

Each year, the highly contagious norovirus causes about 21 million illnesses, including 70,000 hospitalizations and 800 deaths, according to The Centers for Disease Control and Prevention.

Recently, many schools in our area have reported low attendance due to illness.

Health experts say this isn't surprising since viruses, like the norovirus, spread the quickest in schools, hospitals and nursing homes.

There isn’t a particular treatment or vaccine against norovirus but Spradling says the best defense is remembering not to skip the sink.

Health experts say symptoms of the norovirus last for about two days.

10 Vitamin D Deficiency Symptoms Many Doctors Miss

Flu is actually vitamin D deficiency disease. It is not a happenstance occurrence because you didn’t get a flu shot or sat next to a coughing person at Church or on the train.

Dr. John Cannell of the Vitamin D Council and one of the most preeminent Vitamin D researchers in the world today, has identified that vitamin D helps produce the antimicrobial peptides that protect against the flu. This is why people are more prone to the flu in winter when Vitamin D producing sunshine is minimal or nonexistent at some latitudes, or people are too bundled up to get enough skin exposed in the first place.

Scientific research bolsters Dr. Cannell’s suggestion that vitamin D deficiency is why people get the flu. A study published in the journal Nature Immunology further explains how vitamin D protects us by properly activating T cells, an important part of the immune system:

“When a T cell is exposed to a foreign pathogen, it extends a signaling device or ‘antenna’ known as a vitamin D receptor, with which it searches for vitamin D.

Another sign of late HIV infection are nail changes, such as clubbing (thickening and curving of the nails), splitting of the nails, or discoloration (black or brown lines going either vertically or horizontally).

Often this is due to a fungal infection, such as candida. "Patients with depleted immune systems will be more susceptible to fungal infections," Dr. Malvestutto says.

Another fungal infection that's common in later stages is thrush, a mouth infection caused by Candida, a type of yeast.

"It's a very common fungus and the one that causes yeast infections in women," Dr. Malvestutto says. "They tend to appear in the mouth or esophagus, making it difficult to swallow."

Ron woke up one day to find white patches on his tongue. He had thrush. For him, "It was not bothersome other than I didn't like having it." The infection was hard to get rid of, but finally cleared up after Ron started taking drugs to combat HIV.

Cognitive problems could be a sign of HIV-related dementia, which usually occurs late in the course of the disease.

In addition to confusion and difficulty concentrating, AIDS-related dementia might also involve memory problems and behavioral issues such as anger or irritability.

It may even include motor changes: becoming clumsy, lack of coordination, and problems with tasks requiring fine motor skills such as writing by hand.

Cold sores (oral herpes) and genital herpes can be a sign of both ARS and late-stage HIV infection.

And having herpes can also be a risk factor for contracting HIV. This is because genital herpes can cause ulcers that make it easier for HIV to enter the body during sex. And people who have HIV tend to have more severe herpes outbreaks more often because HIV weakens the immune system.

    Now that we talked about why you have sugar withdrawals, let’s talk about what the symptoms are. After coming off of sugar over 50 times myself and helping hundreds to the same, I have found that sugar addicts actually have different symptoms when they are coming off of sugar. And I don’t really like to give you a long list of negative things to “expect” because maybe none of these will happen to you, only one of them or a bunch of them. It can be helpful to be kind of prepared though so you don’t think something weird is happening while you are breaking this sugar addiction. Check out this one great tool, a free video that I made for you called The 3 Mistakes Sugar Addicts Make and How to Avoid Them. Here is a list of the sugar withdrawals I personally experienced and those I have seen come off sugar and keep in mind they usually only last for a few days if even that:

    1. Feeling sad or down. I will admit, this is then number one thing I would experience when I would come off sugar. But have hope, it would only last a few days, thank God! That is one thing that really motivated me to stay away from sugar because I hate feeling sad and it started to not be worth it, the trade-off of having sugar to being really down for a few days. For me I know this is a major sugar withdrawal because I do NOT experience sadness on a regular basis, only when I am coming off sugar. Its very important if you struggle with depression already, that you guard yourself against this and make sure are aware of this. The good news is, I have seen many people who struggle with moodiness and depression GREATLY improve when they no longer have a sugar addiction. Personally I think a lot of people who struggle with this would see an improvement when they break the sugar addiction.
    2. Headaches. I personally never had this sugar withdrawal but I have heard some say they do.
    3. Fatigue. If you have been jacked up on sugar all the time, your body is used to that rush but you have also really stressed out your adrenal glands, which can make you more tired. The ironic thing is, since I no longer am a sugar addict if I do have sugar, I am so tired that night, it literally puts me to sleep. I really can’t believe it! And when I wake up the next day, I almost feel hung over I am so tired. I never realized that as much when I ate sugar all the time.
    4. Sleep patterns affected. Remember you are detoxing off a poisonous substance that is toxic so you are going to be detoxing as it gets out of your body. If you were addicted to sugar, your body was all out of whack from having blood sugar spikes to insulin surges and your body needs some time to balance back out.
    5. Sugar cravings. Now this one is the obvious side effect. Once you stop eating sugar, one sugar withdrawal can be ridiculously intense cravings for it. Remember, you may be stopping something that has been a habit of yours for 20 years so give yourself a break! Its normal to crave something that has been a part of your life for so long not only mentally but physically as well. Be encouraged that sugar cravings DO go away.

    Take “The Quiz” to self-diagnose whether you even are a sugar addict or not, click here.

    One of the most important things about breaking a sugar addiction is learning how to think differently about sugar and how you resist temptation in your life. Because if you get off sugar but don’t know how to stay off it, that is something that can be very frustrating. If you want to check out a free internet seminar I am doing click here or go to http://sugaraddictionspecialist.com/internet-seminar/

    Be on the lookout for your own sugar withdrawals and feel free to leave a comment and let us know what yours were so we can all know what to look out for.

    Mold toxicity is often the end result with constant exposure to mold of a toxic substance. A common misconception among allergists who are untrained in this type of toxicity levels in humans, which is technically not their area of expertise unless they have trained specifically in environmental medicine with their background in immunology, is to do general allergen testing. Most tests usually result in an unequivocal result, a 2+ or less. This induces some physicians to order allergy shots, regardless. These shots are absolutely worthless (and could possibly be harmful) to a person who has been heavily exposed to these mycotoxins as they are already in a state of toxicity. If anything, this could exacerbate the problem. Because many doctors are not trained in this field, they may try to "guess" at a diagnosis.

    In laymen's terms, molds produce mycotoxins. These substances, although unseen by the naked eye, are ingested and then enter the body through the skin, mucous and airways. Once ingested, mold has the requirements to colonize and spread. In doing this, it can compromise the immune system and damage everyday processes of the body. Mold and yeast are interchangeable only in their dimorphic state, which is often a big misconception, although both are fungi. There has been a theory of a connection between Autism Spectrum Disorder onset and Candida Albicans in the body. New studies are being conducted during the first quarter of 2006. Updates will follow.

    Fungi, which include yeasts, moulds, smuts and mushrooms, are responsible for causing four types of mycotic (fungal) disease:

    1. Hypersensitivity - an allergic reaction to moulds and spores;

    2. Mycotoxicosis - poisoning by food products contaminated by fungi

    3. Mycetismus - the ingestion of preformed toxin (toadstool poisoning)

    4. Infection (systemic) - (Mycotoxicosis; the subject below)

    The following are a list of the most common symptoms of fungal exposure (bear in mind, people never fit all of below criteria). Most people with some forms of Mycotoxicosis meet at least 8 (recent symptoms) of the following criteria:

    • Fibromyalgia/mps (and several correlated symptoms)
    • Respiratory distress, coughing, sneezing, sinusitis
    • Difficulty swallowing, choking, spitting up (vomiting) mucous
    • Hypersensitivity pneumonitis
    • Burning in the throat and lungs (similar to acid reflux and often misdiagnosed as such)
    • Asthmatic signs; wheezing, shortness in breath, coughing, burning in lungs, etc.
    • Irritable bowel syndrome, nausea, diarrhea, sharp abdominal pains, stomach lesions
    • Bladder, liver, spleen, or kidney pain
    • Dark or painful urine
    • Dirt-like taste in mouth, coated tongue
    • Food allergies/leaky gut syndrome/altered immunity
    • Memory loss; brain fog, slurred speech, occasionally leading to dementia
    • Vision problems
    • Swollen lymph nodes
    • Large boils on neck (often a sign of anaphylaxis )
    • Yellowing of nails, ridges, or white marks under nail
    • Thyroid irregularities, sometimes leading to complete dysfunction; adrenal problems
    • Headaches
    • Anxiety/depression, heart palpitations - confusion, PTSD
    • Extreme blood pressure, cholesterol, or triglycerides irregularities
    • Ringing in ears, balance problems (very common), dizziness, loss of hearing (aspergillus niger)
    • Chronic fatigue (also included under this classification directional confusion)
    • Intermittent face flushing; almost always systemic, Called the Mylar Flush (neurological))
    • Night head sweats, and drooling while sleeping, profuse sweating
    • Multiple chemical sensitivity; only upon exposure to Stachybotrys and Chaetomium
    • Nose bleeds (stachybotrys)
    • Bruising/scarring easily; rash or hives, bloody lesions all over the skin (Often systemic, see images; skin )
    • Reproductive system complications; infertility, changes in menstrual cycles, miscarriage
    • Sudden weight changes (Detoxifier genotypes tend to gain weight, non-detoxifier genotypes tend to lose weight)
    • Cancer
    • Hair loss, very brittle nails, temporary loss of fingerprints (in rare cases)
    • Joint/muscle stiffness and pain
    • Irregular heart beat/heart attack
    • Seizures, inadvertent body jerking, twitching, inadvertent facial movements or numbness in face
    • Hypersensitivity when re-exposed to molds, which can lead to anaphylaxis
    • Anaphylaxis upon re-exposure to mycotoxin producing molds
    • Death, in extreme cases

    Note: despite inaccurate and misleading reports by theorists regarding immuno-compromised, babies, and the elderly being more susceptible, this is a big misconception as exposure to the T-2 mycotoxins found in many types of current indoor molds will poison anyone in time; no one is immune. The reason for this conflicting information is that studies have never been conducted to prove this. If so called experts are going to make such a broad and misleading statement, they may as well say that this same category of people is more susceptible to SARS, West Nile Virus, AIDS, and cancer. The T-2 mycotoxins found in many of these molds are the exact same T-2 mycotoxins that have killed widespread groups of innocent people with Yellow Rain, a biological warfare agent.

    It is not clear, however, if frequent heartburn actually causes people to develop asthma. Although many people who have heartburn also have asthma and vice versa, the reasons for this overlap aren't clear.

    Experts think stomach acid can trigger nerves in the chest to constrict your breathing tubes in order to keep acid from entering. Again, a simple pH test to look for acid in your esophagus may help you get to the bottom of the problem.

    Nausea is associated with so many things that it can be hard to attribute it to reflux. But, says Dr. Coyle, "in some people, the only manifestation they have of reflux is nausea. If you have nausea and can't figure out why, one of the things [to] think about is reflux."

    And if the nausea tends to come on right after meals, that's even more of an indication that it might be acid reflux. If so, a regular antacid treatment such as an over-the-counter acid-countering medicine could cut down on your discomfort.

    If your mouth all of a sudden starts producing extra saliva, it could be water brash, which is highly suggestive of acid reflux, Dr. Coyle says.

    It involves the same nerves and reflex as when you vomit. "It is your body trying to wash out an irritant in your esophagus," he says.

    Over time, the continuous cycle of damage and healing after acid reflux causes scarring, Dr. Pfanner says. This, in turn, causes swelling in the lower-esophagus tissue, resulting in a narrowing of the esophagus and difficulty swallowing.

    Eine Grippe (Influenza) kann sehr unterschiedlich ablaufen: Milde, erkältungsähnliche Grippesymptome sind ebenso möglich wie eine schwere Erkrankung, die im Extremfall sogar tödlich enden kann.

    Gerade anfangs kann man die Grippe leicht mit einer Erkältung verwechseln. Der Unterschied zwischen Influenza und Erkältung zeigt sich im Verlauf und in der Schwere der Erkrankung.

    Die Grippe ist eine plötzlich auftretende, fieberhafte Viruserkrankung, die durch verschiedene Grippeviren entsteht. Da sie im Winter häufiger vorkommt, wird sie auch "saisonale Grippe" genannt.

    Typischerweise tritt die Grippe zeitlich und örtlich gehäuft auf: Dann spricht man von einer Grippewelle oder Epidemie. In größeren Zeitabständen von mehreren Jahren bis Jahrzehnten breitet sich die Influenza länderübergreifend beziehungsweise weltweit aus – dies bezeichnet man als Pandemie.

    Die Erkrankungs- und Sterberate schwankt bei der Influenza allerdings stark. In manchen Jahren steigt die normale Sterblichkeitsrate trotz Grippefällen gar nicht an. Doch während einer einzelnen Grippesaison können auch mehrere Tausend Menschen mehr als sonst sterben. So gab es beispielsweise durch die besonders heftige Grippewelle 2012/13 in Deutschland über 20.000 zusätzliche Todesfälle. Daher ist eine Influenza nie als harmlos anzusehen.

    Typisch für die echte Grippe (Influenza): Man fühlt sich schlagartig richtig krank.
