Learn more about the ﬂu and how to protect against it.</p>||<h2>What is influenza?</h2><p>Inﬂuenza (ﬂu) is a lung infection caused by speciﬁc inﬂuenza viruses. People can get the ﬂu at any time of year, but it is more common in the fall and winter. <br></p>||<h2>Key points</h2><ul><li>Inﬂuenza (ﬂu) is not the same as the common cold. </li><li>Flu is caused by the inﬂuenza virus. </li><li>Most people who get the ﬂu do not get seriously ill and will have symptoms for two to seven days. </li><li>You can reduce your risk of getting the flu by getting a ﬂu shot each year and washing your hands frequently. </li><li>If your child has the flu they should stay home and rest. If they do not start to feel better after a few days or if symptoms get worse, call your child’s primary care provider.
</li></ul>||<h2>Common symptoms of the flu</h2><p>People who get the flu usually have some or all of the following symptoms:</p><ul><li>
<a href="/article?contentid=30&language=english">fever</a></li><li>muscle aches</li><li>
<a href="/article?contentid=748&language=english">sore throat</a></li><li>
<a href="/article?contentid=774&language=english">cough</a></li><li>fatigue and weakness</li></ul><p>Most of these symptoms usually last for two to seven days. Rare but serious complications of the flu include bacterial pneumonia and influenza infection of the brain. </p>||<h2>The flu can be serious for some people</h2><p>Most people who have the ﬂu will not become seriously ill. But the ﬂu can be more serious for some people. Typically, those most at risk are in one of the following groups:</p><ul><li>Children under two years of age</li><li>People 65 years of age or older</li><li>People living in long-term care facilities such as a nursing home, a home for the aged or a chronic care hospital </li><li>People with chronic heart, lung or kidney disease</li><li>People with diabetes, cancer, immune system problems or sickle cell anaemia</li><li>Children and teenagers aged six months to 18 years who have been treated with
<a href="/article?contentid=77&language=english">acetylsalicylic acid (ASA)</a> for long periods </li><li>People who have trouble clearing mucus from their nose and throat because of weakness or underlying illness</li></ul><p>These groups, and anyone who lives or works with people from these groups, should generally be immunized each year with the ﬂu vaccine (flu shot). That way, people from these high-risk groups are less likely to be infected with the ﬂu. </p>||<h2>How the flu spreads</h2><p>The ﬂu spreads very easily from an infected person to others through coughing and sneezing. It is also spread by touching objects after someone with the ﬂu has touched them. </p>||<h2>Treating the flu</h2><p>If you or your child have the flu, stay home and rest. Usually, treatment is focused on the symptoms the person is feeling. For example, if your child has a fever, you can give them acetaminophen or ibuprofen to reduce fever. </p><p>Do not give <a href="/article?contentid=77&language=english">acetylsalicylic acid (ASA)</a> to a child under 16 years of age. Do not give cough medicines to children under six years of age. Always read the label before giving any medicine.</p><p>In addition to fluids and pain medicine, other ways to treat flu symptoms include:</p><ul><li>applying heat on painful areas for short periods of time using a hot water bottle or heating pad to reduce muscle pain</li><li>taking a warm bath</li><li>gargling with a glass of warm water</li><li>using saline drops or spray and suction to clear a stuffy nose</li><li>keeping your home smoke free</li></ul><p>Call your child’s primary care provider if the above measures do not relieve your child's flu symptoms and your child feels worse or if you are worried.</p><h2>If your child has the ﬂu in the hospital </h2><p>Your child will be placed in a single room and will not be able to visit the playroom until they are feeling better. Ask the child life specialist to bring toys and supplies to your child’s room.</p><p>Hospital staff will be wearing a mask, eye protection, gloves and gowns when they visit.</p><p>Wash your hands often, either with alcohol-based hand rubs or soap and water, before and after touching your child and before leaving your child's room. Hospital staff should wash their hands as well.</p><p>If you or anyone else who has visited becomes ill with symptoms of the ﬂu, let your child's doctor or nurse know. </p>||<h2>Preventing the flu</h2><p>To help prevent the flu, it is important that you and your child get a ﬂu shot every year.</p><p>You should also
<a href="/article?contentid=1981&language=english">wash your hands</a> well. This can help prevent you from catching or spreading the ﬂu. This is very important in hospitals, but it is true in other places as well. </p><p>Clean surfaces in your house regularly, especially ones you touch often. These include doorknobs, fridge doors, light switches, phones and computers.</p><p>If you have the ﬂu, you should do the following things to avoid spreading it.</p><ul><li>Always cover your mouth and nose with a tissue when you cough or sneeze. Throw away the tissue, then wash your hands. These steps will help prevent spreading the ﬂu and other respiratory viruses. </li><li>Do not visit the hospital when you are sick with symptoms of the ﬂu. No one who is sick should visit a patient in the hospital, even if they are a relative. </li></ul><h3>The ﬂu shot </h3><p>The inﬂuenza vaccine (ﬂu shot) is made from pieces of killed or live but weakened ﬂu viruses. It contains three or four different types of ﬂu viruses. A person who receives the ﬂu shot develops immunity for the types of ﬂu in the vaccine. Immunity means the body builds up protection against the virus. </p><p>The body needs about two weeks after the shot to build up protection against the virus. This protection lasts for about six months.</p><p>The ﬂu shot will not protect against other viruses, such as viruses that cause the common cold. </p><p>For tips on how to make vaccinations as easy and pain-free as possible, please read the articles, <a href="/article?contentid=989&language=english">Needle pokes: Reducing pain in infants aged up to 18 months</a> and <a href="/article?contentid=990&language=english">Needle pokes: Reducing pain in children aged 18 months or over</a>.<br></p><h3>A ﬂu shot every year </h3><p>People need a new ﬂu shot every year. The ﬂu virus changes each year, so a different vaccine has to be used each year too. Doctors and scientists ﬁnd out the types of ﬂu virus that are circulating around the world. The vaccine is then made to protect against the types that are most likely to occur each year.</p><h3>Most people can get a ﬂu shot </h3><p>The ﬂu shot is free to people living in Ontario. Anyone older than six months of age should have the ﬂu shot unless there is a reason not to. The best time to get the flu shot is in the fall, before the flu becomes more common. Ask your child's primary care provider if your child can get the ﬂu shot. </p>||<h2>When to seek medical attention</h2><p>Go see a doctor or to hospital if your baby is less than three months old and:</p><ul><li>has a fever</li><li>has fast or difficult breathing</li><li>is vomiting or not feeding</li></ul><p>Go see a doctor if your child:</p><ul><li>is more sleepy than usual</li><li>is more fussy than usual</li><li>is not drinking enough fluids or has not peed at least every six hours when awake</li><li>is vomiting</li><li>is having chest or stomach pain</li><li>is not feeling better after five days or gets better but then suddenly gets worse</li></ul><p>Call 911 or go to the nearest emergency department immediately if your child:</p><ul><li>is breathing quickly, or seems to be working hard to breathe</li><li>is very weak, dizzy, hard to wake up or does not respond well</li><li>is very fussy or cannot be comforted</li><li>is limping or refusing to walk</li><li>has bluish or dark-coloured lips or skin</li><li>has a stiff neck, severe headache or a seizure</li><li>has a very fast heart rate, even when the fever is down</li></ul><p>If you have any concerns, call your doctor or your local public health agency.
