University Health Network has grown to be one of the largest research and teaching hospital networks in Canada - pioneers in improving the lives of patients. Our long history of health professions education at Toronto General, Toronto Western, Princess Margaret and Toronto Rehab hospitals has consistently advanced the science of education.
University Health Network is a health care and medical research organization in
Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international
source for discovery, education and patient care.
Being touched by illness affects us in different ways. Many people want to give back to the community
and help others. At UHN, we welcome your contribution and offer different ways you can help so you can find one that suits you.

Frequently asked questions about the flu
What are the symptoms of influenza?
Influenza is a serious contagious viral respiratory infection.
Symptoms can range from mild to severe. Typically, influenza starts with a headache, chills and cough.
This is followed by fever, muscle aches, fatigue, loss of appetite, runny nose, sneezing, watery eyes, throat irritation, and in children, sometimes diarrhea and vomiting. Most people recover from influenza within a week to 10 days.
The influenza season usually lasts from October to April, but the exact time can change every year. Typically the peak time for influenza is end of December to mid-January.
Is Influenza serious?
Influenza is one of the top 10 infectious diseases in Ontario. While most healthy adults feel miserable for a few days, for some people, influenza can be serious or life-threatening.
Those most at risk include:
It is estimated that, in a given year, an average of 12,200 hospitalizations related to influenza and approximately 3,500 deaths attributable to influenza occur in Canada.
Complications include pneumonia, bronchitis, and sinus and ear infections. Influenza and other respiratory virus infections can also make chronic conditions, such as asthma, worse.
How are these viruses spread?
Influenza and other respiratory viruses are spread by droplets that are made when infected people cough or sneeze. You can either catch the virus directly from an infected person or by touching surfaces contaminated with the virus.
You are most likely to spread the virus when you have symptoms.
How do I avoid getting influenza and other respiratory viruses?
Getting vaccinated against influenza will provide some protection against you getting influenza. Given that the vaccine isn't perfect and that multiple other viruses can cause similar illness, it is important that we don't just rely on the flu shot for protection.
There are several other important infection control measures that can help you avoid getting ill with or
spreading a respiratory infection.
Limiting the spread of respiratory viruses is everyone's responsibility.
Do I have to get vaccinated?
We encourage you to get the influenza vaccine, but at this time the influenza vaccination is not mandatory for healthcare workers at UHN. It's not that we think influenza vaccination isn't important, we think it's incredibly important and would like to see all of our staff lining up at the flu carts this year.
We also acknowledge, however, that the flu shot isn't perfect and this is why we need you to take other measures as well to protect yourself and our patients from respiratory viruses, including influenza.
If you are working on a unit where an influenza outbreak has been declared, it is required that you be vaccinated and/or take prophylactic medication until the outbreak is over.
Employees who are not vaccinated and refuse the prophylactic medication may be placed on an unpaid leave of absence (LOA) until the outbreak is over. If an employee is placed on an unpaid LOA they may use banked lieu time or vacation credits. If an employee is not able to receive the vaccine for medical reasons and a medical certificate is provided, the employee will be reassigned where possible during the outbreak. This is recognized in the ONA collective agreement.
I got vaccinated last year. Why do I need to get it again?
It's best to get the vaccine every year to keep yourself healthy. Different influenza viruses circulate every year and immunity from the influenza vaccine decreases over time. Even if there is no significant change in the virus, your body's immunity level declines over several months.
How effective is the influenza vaccine?
The effectiveness of the seasonal influenza vaccine varies from year to year. Some years the vaccine is more effective than others because it's a closer match to what's circulating in the community.
Overall, decades of experience suggest that the influenza vaccine is, on average, 60 per cent effective in preventing infection in healthy adults. Evidence also shows that even if a person gets influenza after being vaccinated, their illness will be less severe. Although the vaccine is not perfect, getting immunized is one of the best ways available to prevent influenza infection.
Remember that influenza vaccine can only prevent influenza, not influenza-like respiratory illness that may be caused by other viruses.
I heard that getting vaccinated year after year may cause the vaccine to be less effective in future years. Is that true?
Some new research suggests that, in certain years, having been vaccinated before can make the vaccine a bit less effective in the current year. The medical community is currently investigating this intermittent phenomenon but as it stands now, annual vaccination is still recommended and likely will continue to be recommended.
Can you get influenza from the vaccine?
No, you can't get influenza from the vaccine because the viruses contained in the vaccine are inactivated (killed) and cannot cause influenza.
You can still catch the other respiratory viruses that are circulating at the same time as influenza. Also, if you have been exposed to influenza right before vaccination (i.e., before your body has built immunity to the virus from vaccination), you may get sick from that infection and mistakenly attribute it to the vaccine.
What is UHN's approach to influenza season this year?
As many of you know, recently a number of our peer hospitals implemented a policy of mandatory vaccination or masking throughout the flu season. UHN has not implemented this policy. We instead continue our policy of supporting vaccination and most importantly, imploring our staff not to come to work when ill with influenza-like illness.
We hope that with an honest approach to vaccination and information on general well-being, as well as an improved process, we can boost our vaccination rates to over 60 per cent range.
What should I do if I also work at a hospital that isn't part of UHN?
If you work at other hospitals you need to find out what their policy is this year and follow that while you work there.
I'm allergic to eggs. Can I get the vaccine?
Yes, most people with an egg allergy can get the influenza vaccine. If you are able to eat baked goods with eggs then you are able to get the vaccine. If you have a severe egg allergy (anaphylaxis), you need to speak to your doctor. You may be able to get the vaccine in a medical clinic or in your allergist's office.
I'm pregnant. Can I still take the vaccine?
In most cases, not only is it safe, it is recommended that pregnant women get vaccinated. Some studies suggest that pregnant women are at greater risk of developing complications from influenza.
Pregnant women who get vaccinated also pass on their immunity to their baby, protecting them from influenza for the first six months of their life.
