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

It’s typically those microscopic and pesky protozoa that cause the more uncomfortable symptoms like diarrhea or loose stools. This is because they release prostaglandin which is substance that causes a loss in chloride and sodium. The result is stools that are watery because the body is attempting to rid itself of the attacker.
Constipation can also be caused because some of the larger parasitic worms can lodge themselves in the intestines and cause a blockage. Over-the-counter stool softeners and a healthy diet should clear up natural bouts of constipation. You may have a parasitic worm causing a blockage if stool softeners don’t provide relief.
A common condition caused by these intestinal parasites is irritable bowel syndrome. This is a painful and uncomfortable condition that is a result of the parasite irritating the wall of the intestine and causing swelling. Many doctors have been quick to dismiss IBS as just something people must cope with. In the year 2000, researchers in England did a study that showed a significant link between the parasite giardia and irritable bowel syndrome. Ridding the body of this parasite gave great relief to the patients who had previously been diagnosed with IBS.
Since parasites don’t always stay put in the intestines, but rather move about and enter the blood stream, nervous system, and the organs, joint and muscle pain can be a symptom to look out for. This joint pain can commonly be mistaken for arthritis when in reality it is caused by inflammation due to the parasites becoming encased in a sac and existing despite our body’s best efforts to expel it.
Some parasites can cause a person to become agitated, nervous, or anxious. Researchers believe this is due to the body reacting in a way to try and rid itself of the foreign body. It’s also known that parasites release waste which can have an adverse effect on the central nervous system.
People who experience anxiety and nervousness that doesn’t improve with conventional treatments like medication or even meditation may have a parasitic infection. There have been reports of people who underwent a parasite cleanse and experienced a dramatic improvement with their anxiety symptoms.
Sleep loss can also be associated with the presence of parasites. Much like the anxiety and nervousness that can be caused by the toxins the parasites release, sleep loss occurs with the body’s attempt to deal with the parasite invasion. The liver makes valiant attempts to rid the body of the toxic waste the parasites leave behind which can cause sleep disturbances.
Another cause of sleep disturbances is associated with pinworms. These tiny white worms exit the body when the host is sleeping to deposit their eggs around the anus. This causes extreme itching and discomfort.
People, especially children, who have a parasitic infection, have also been known to grind their teeth while sleeping. This is also associated with the nervousness that can be caused by the toxins the parasite is producing in the body.
Generally, parasites can weaken your immune system. This leads to being more susceptible for infections like the common cold and flu. You may have a parasite that is compromising your immune system if you find that you chronically experience cold and flu symptoms. It’s not abnormal to come down with a cold or flu occasionally, but when it seems like you are always fighting one off, it may be caused by a parasite weakening your body’s defenses.
Skin conditions are also a common symptom of having a parasitic infection. They can be very uncomfortable, unsightly, and painful to deal with. You may think that only parasites that feed off skin cells will cause these conditions, but that isn’t quite the case. While it’s true that fungi like ringworm cause itchy, patchy skin lesions, intestinal invaders like worms and protozoa also cause irritating skin conditions.
Hives, eczema, and other rashes have all been linked to intestinal parasites. It’s not known exactly why, but one theory is that the toxins released in the blood stream affect the skin from the inside out. Skin conditions that are not caused by parasites should clear up with topical ointments or steroid treatments prescribed by doctors. If the condition doesn’t clear up with these methods then the culprit may be a parasite.
When it seems like typical treatments are not providing any relief for any of these parasitic infection symptoms, it may be time to try a parasite cleanse. If left untreated, parasites will continue to multiply and cause damage inside the body. Some can live for years and years causing painful parasite symptoms the entire time.
From its discovery until 2006, confirmed cases of Zika virus infection were rare, although cases were reported during the 60's in Africa and South-East Asia. Analysis suggested that the African and Asian strains emerged as two distinct lineages.
The first outbreak outside of Africa and Asia was documented on Yap Island in the Federal States of Micronesia, in 2007.
When your blood vessels are constricted, your body heats up. So when you suffer from anxiety and your body is naturally on edge as though you're facing danger, and ultimately you experience the same body temperature increase as you would if you were experiencing a dangerous situation.
It's not uncommon for this body heat increase to then be followed by sweating, which may eventually cause you to feel colder as well. All of these are a natural part of living with anxiety, especially intense anxiety.
That hot feeling can be very disruptive to your life. Those that experience hot flashes at night often report significant problems sleeping, as their sheets start to feel drenched in sweat and their body feels too warm to get any rest. Those that experience it during the day may find that they are uncomfortable everywhere they go. They may even worry that others are judging them, increasing their anxiety and the length of their hot flash.
Hot flashes are not something that you can stop once they've started. They'll eventually stop on their own when your anxiety trigger goes away. But you can control how much the symptoms affect you by integrating the following:
- Sleep in Cooler Rooms A cooled down room with several thinner blankets/sheets will allow you to easily adjust your own temperature as needed when you are trying to sleep at night. You may feel hot or cold throughout the night, but you'll be able to easily remove or add layers as needed so that the hot flashes affect you less.
- Can't Sleep, Get Up Those that often lose sleep from hot flashes should take a moment when a hot flash is coming to simply cool down. Hot flashes can fuel themselves, in a way, because when you have a hot flash you start to worry that you won't get sleep, which increases anxiety and causes your hot flash to continue for longer. Get up and walk around if a hot flash is coming so that you give yourself a break from the hot flash stress.
- Write it Out When your hot flashes are caused by thoughts and worries that you can't seem to shake, write out those thoughts on a piece of paper or in some type of diary. When your brain knows that your worries and thoughts are in a permanent place that you can refer to later, it tends to focus on them less, allowing you to rest your brain and hopefully cool your hot flashes.
Once the hot flash begins, waiting until it decreases is really your only option. There are a few ways to cool down, and distracting yourself can be valuable, but a hot flash is a natural body response and one that you can't turn off. If anxiety is causing your hot flashes, you'll need to find a way to reduce the anxiety itself.
You have a lot to consider, because while there are many anxiety treatments, they will not work for everyone. Some examples of treatment options include:
- Regular Exercise Regular exercise is designed for more than fitness. Your body needs exercise in order to effectively burn off stress and improve hormone and neurotransmitter production, both of which improve anxiety symptoms. Exercise can be a bit stressful for someone that finds hot flashes to cause anxiety, but it's absolutely necessary for fighting off anxiety symptoms.
- Therapy Cognitive behavioral therapy, as well as other forms of therapy, has proven itself to be effective at reducing anxiety. While therapy is not for everyone and some people may find the costs to be too expensive, those that have the time and energy to enroll in therapy are likely to benefit from its outcomes.
- Medications Medications should be a last resort for all mental health issues, especially anxiety, but if nothing else works they can be helpful. Several antidepressant and anxiolytic drugs have reduce anxiety symptoms for those with hot flashes, but be warned - it's also possible for these same drugs to cause hot flashes as a result of the way they affect the CNS.
Everyone reacts to anxiety treatments differently, because everyone has different anxiety causes, biochemistry, symptoms, and more. So the above list is nowhere near extensive, and there are several very effective anxiety treatments that have been developed for specific symptoms and types of anxiety.
I've helped thousands of people that suffer from hot flashes from their anxiety reduce their anxiety symptoms. I start all of them off with my 7 minute anxiety symptoms test. This free test will examine your anxiety and provide recommendations for treatment.
The thyroid, a small gland located in the front of the neck, produces hormones that regulate the rate at which every cell in your body functions. Accordingly, thyroid disease can significantly impact a person’s overall health. If the thyroid produces too little thyroid hormone, the body’s metabolism slows, causing listlessness and other symptoms; an overproduction of thyroid hormone results in feelings of nervousness and a faster heart rate. Other thyroid diseases result in different symptoms
Visit our thyroid resources page for a detailed description of the thyroid, its function, and thyroid disease symptoms. Depending upon the type of thyroid disease, symptoms can vary radically:
Hyperthyrodism: A condition in which the thyroid produces too much hormone, hyperthyroidism most commonly affects women between the ages of 20 and 40; however, women of any age and men can be affected as well. Graves’ disease, a condition in which the immune system stimulates the thyroid gland, is the most common cause of hyperthyroidism but there can be other causes including thyroid nodules (small bumps on the thyroid) and taking too much thyroid hormone medication to treat a separate condition. This thyroid disease’s symptoms may include the following:
- Nervousness, irritability
- Increased sweating
- Increased, sometimes irregular, heart rate
- More frequent bowel movements, diarrhea
- Shaky hands
- Unexplained weight loss
- Lighter period(women)
- Erectile dysfunction (men)
Thyroid Cancer – Thyroid cancer arises when small tumors called thyroid nodules grow on the thyroid gland. Having a nodule on your thyroid is quite common, and 90% to 95% of thyroid nodules are noncancerous. However, those that are cancerous can spread through the body, or metastasize, and become life-threatening. Thyroid cancer often exhibits no thyroid disease symptoms, and is typically found during a routine examination. Malignant nodules tend to be firmer than benign nodules, so they can often be identified by touch.
- Stiff neck
- Light sensitivity
- Seizures - as condition progresses
- Altered mental state - in advanced stages
- Shock - in advanced stages
- Flu-like symptoms - viral infections
Proper breast health and early prevention of both benign and malignant disease are of the utmost importance in womens' health. Knowing all of the signs and symptoms of common conditions of the breast and surrounding tissues, gives you the knowledge needed to help live a long and healthy life. Whenever any of these symptoms emerge, make an appointment with your doctor to find the true cause of them.
Changes in Shape: Obvious changes in the shape of the breast sometimes indicates breast disease such as cancer or inflammatory breast cancer. The change of size, or shape of the breast often cause the breasts to appear asymmetrical, with one breast being noticeably larger than the other, or misshapen. The texture of the breast also changes, in addition to the shape and size. Small dimples appear, or bumps, on the surface of the skin of the breast.
Household bleach mixed at a ratio of 1:32 is a inexpensive and effective way of destroying the virus on washable items.
Cat flu cannot be spread to humans.
Feline Herpes Virus symptoms usually lasts for about 7 -14 days and Calicivirus symptoms usually last for about 7 - 10 days.
Will my cat be a carrier of Cat Flu?
When cats have recovered from Cat Flu they continue to shed the virus especially at times of stress. Although they do not show any symptoms they have in fact become a carrier of the virus.
With Feline Herpes Virus the carrier state can last the lifetime of the cat.
How can I prevent Cat Flu
There are vaccinations available for Feline Herpes Virus-1 and Feline Calicivirus (FCV) Discuss a vaccination regime with your veterinarian.
Avian Flu Symptoms: How Can You Tell If You Have H5N1?
North America's first death from the H5N1 virus, also known as avian or bird flu, was reported in Alberta today, contracted by a victim who had just returned from China. While officials have been quick to reassure Canadians that this was an isolated incident and not related to the seasonal flu, this potentially fatal illness has many wondering about the symptoms of this influenza.
Most avian flu viruses do not infect humans, but some, like the highly pathogenic H5N1, can cause severe infections, according to the U.S. National Institutes of Health.
When the H5N1 strain of bird flu appears in humans, it mimics a severe case of the flu, like H1N1 (swine flu). Flu.gov, the U.S. site for flu information, notes that symptoms of H5N1 in humans include:
- Acute respiratory distress
- Shortness of breath/difficulty breathing
The diagnosis of H5N1 based on symptoms alone is difficult because they are so similar to other flu strains; laboratory testing is required to confirm infection, according to the the US Centers for Disease Control and Prevention (CDC)
The bird flu is generally spread to people through direct contact with infected birds or poultry livestock. The H5N1 virus can live in the environment for extended periods, but cannot be contracted by eating properly handled, cooked poultry or eggs, and thus far has not shown any sign of spreading easily from person to person, though that is always a likelihood, warns the CDC. As the Lung Association notes, there has been limited transmission in the case of long-term contact with sick relatives.

One of the best ways to prevent seasonal influenza is through yearly immunization because the influenza virus changes each year.
As part of Alberta's influenza immunization program, Albertans 6 months of age and older are able to receive influenza vaccine, free of charge, at public health clinics, pharmacies and doctor’s offices.
- About immunization
- Where to get immunized
- Contact your local pharmacist or physician for details on vaccine availability
Alberta Health is offering Albertans one type of influenza vaccine free of charge. This vaccine, called Fluzone, is offered as an injection, contains 4 strains of influenza virus and is a safe and effective vaccine for all ages.
Having multiple types of vaccines increases the complexity of our immunization program. Offering one type of vaccine to Albertans at mass public clinics, pharmacies and doctor’s offices means we can offer a more efficient program where vaccine is available for everyone across the province when clinics open.
Alberta Health will not offer FluMist (the nasal spray) this season. In previous years, FluMist had been available for children between the ages of 2 and 17.
- In 2016, Canada’s National Advisory Committee on Immunization removed its preferential recommendation for FluMist for children 2–17 years of age. The committee concluded that FluMist and injectable vaccines are equally safe and effective for children.
FLUAD is an influenza vaccine designed to boost the immune response in seniors. This year, FLUAD will not be available at public health clinics. Seniors living in long term care or supportive living will continue to be offered FLUAD free of charge.
- This aligns with recommendations from the National Advisory Committee on Immunization. The committee recommends either FLUAD or a regular four-strain vaccine for seniors.
- Some pharmacists may choose to offer FLUAD to Albertans age 65 and older at a cost. Seniors who wish to be immunized with FLUAD can contact their pharmacies for more information.
- In 2016/17, Canadian estimates on vaccine effectiveness show vaccine was 42% effective against the dominant strain, H3N2.
- This is slightly lower than in 2015/16 when the vaccine was 50% effective and the dominant strain of influenza was H1N1. Vaccine effectiveness is often lower against H3N2 strains of influenza, so this could explain why the vaccine was less effective.
- Even with an effectiveness rating of 42%, immunization is the best way for Albertans to protect themselves and others against influenza.
Vaccine effectiveness varies from year to year but immunization is still the best protection. We do not know how effective this year’s vaccine will be, but we do know that not being immunized offers no protection.
- Alberta has purchased 1.6 million doses of influenza vaccine for the 2017/18 season. This is enough to immunize 35% of the population.
- Total cost: $12.1 million.
- In 2016/17, Alberta Health purchased 1.6 million doses of influenza vaccine.
- Total cost: $12.7 million
- 27% of Albertans (roughly 1.1 million people) received the influenza vaccine
- 64 people died and had lab-confirmed influenza
- 1,653 Albertans were admitted to hospital with lab-confirmed influenza.
- Alberta has offered universal influenza immunization free of charge to residents since 2009.
- The program before 2009 targeted those most at risk of disease and complications.
- 2016/17 – 27.0% (more influenza data is available on the Alberta Health Services influenza website )
- 2015/16 – 27.0%
- 2014/15 – 30.0%
- 2013/14 – 27.6%
- 2012/13 – 23.0%
- 2011/12 – 22.5%
- 2010/11 – 22.0%
Every year we hope to see more Albertans get immunized, and we encourage all Albertans age 6 months and older to be immunized when vaccine is available.
Healthcare workers are strongly encouraged to get immunized. The proportion of health care workers getting vaccinated against influenza in 2016/17 was 63%, compared to 61% in 2015/16.
