Seasonal Influenza

What is Influenza?

Influenza, often called the 'flu', is an infection of the upper airway (e.g. nose and throat) caused by an influenza virus.

A person with influenza is also at risk of other infections. These include viral or bacterial pneumonia, an infection of the lungs. The risk of complications is greater for seniors 65 years and older, very young children, and people who have lung or heart diseases, certain chronic health problems, or weakened immune systems.

What are the symptoms of influenza?

Influenza symptoms can include fever, headache, muscle pain, runny nose, sore throat, extreme tiredness, and cough. Although colds and other viruses may cause similar symptoms, those due to the influenza virus tend to be worse.

Symptoms can begin about one to four days (on average two days) after a person is first exposed to the influenza virus. Fever and other symptoms can usually last 7 to 10 days, with cough and weakness lasting up to two more weeks.

In children, gastrointestinal  symptoms such as nausea, vomiting, and diarrhea may accompany the respiratory phase

What should I do if I get sick?

If you have mild influenza-like symptoms, but are otherwise healthy, stay home to treat your symptoms and avoid infecting others. You can return to normal activities when you have no more symptoms. If you are pregnant, have underlying health problems or your symptoms get worse, contact your healthcare provider for advice or call Newfoundland and Labrador HealthLine - 811 or TTY - 1-888-709-3555 or visit the 811 HealthLine website. 

How can I prevent influenza?

You can play a role in staying healthy and preventing the spread of influenza. To protect yourself and others from influenza, remember to Clean, Cover, and Contain, and follow these simple steps:

  • Clean your hands frequently and keep surfaces clean - Twenty seconds of handwashing with warm water and soap helps removed bacteria and viruses. Remember to wash your hands before and after eating, after using the bathroom, after coughing or sneezing, and after touching surfaces that may have been contaminated by other people. Doorknobs, light switches, telephones, keyboards and other surfaces can become contaminated with all kinds of bacteria and viruses. Regular cleaning and disinfecting of these surfaces can help.

  • Cover your coughs and sneezes - Use a tissue or raise your arm to your face and cough or sneeze into your arm. If you use a tissue, dispose of it as soon as possible and wash your hands immediately. 

  • Contain your illness by staying home and resting - If you go out you may spread your illness to other people. It may take you longer to get better if you are not well rested. 

  • Choose to be vaccinated - Get the annual influenza vaccine (flu shot). 

Encourage others to follow these simple steps. If you have children, be a good role model. Teach them to count to 20 while washing their hands and show them how to cover up when they cough or sneeze.
