Washington, D.C. – Influenza (the flu) is an infection of the nose, throat, and lungs caused by influenza viruses. There are many different influenza viruses that are constantly changing. They cause illness, hospital stays and deaths in the United States each year. The flu can be very dangerous for children. Each year about 20,000 children younger than 5 years old are hospitalized from flu complications, like pneumonia.
Flu illness can vary from mild to severe. While the flu can be serious even in people who are otherwise healthy, it can be especially dangerous for young children and children of any age who have certain long term health conditions, including asthma (even mild or controlled), neurological and neurodevelopmental conditions, chronic lung disease, heart disease, blood disorders, endocrine disorders (such as diabetes), kidney, liver, and metabolic disorders, and weakened immune systems due to disease or medication. Children with these conditions and children who are receiving long-term aspirin therapy can have more severe illness from the flu.
Most experts believe that flu viruses spread mainly by droplets made when people with the flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might get the flu by touching something that has flu virus on it and then touching their own mouth, eyes or nose.
What are the symptoms of the flu?
Symptoms of the flu can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue and sometimes vomiting and diarrhea. Some people with the flu will not have a fever.
How long can a sick person spread the flu to others?
People with the flu may be able to infect others by shedding virus from 1 day before getting sick to 5 to 7 days after. However, children and people with weakened immune systems can shed virus for longer, and might be still contagious past 5 to 7 days of being sick, especially if they still have symptoms.
How can I protect my child against the flu?
To protect against the flu, the first and most important thing you can do is to get a flu vaccine for yourself and your child.
A new flu vaccine is made each year to protect against the three flu viruses that research indicates are most likely to cause illness during the next flu season. Flu vaccines are made using strict safety and production measures. Over the years, millions of flu vaccines have been given in the United States with a very good safety record.
Is there a medicine to treat the flu?
Antiviral drugs can treat flu illness. They can make people feel better and get better sooner and may prevent serious flu complications, like pneumonia, for example, that can lead to hospitalization and even death. These drugs are different from antibiotics, but they also need to be prescribed by a doctor. They work best when started during the first 2 days of illness. It’s very important that antiviral drugs be used early to treat the flu in people who are very sick (for example people who are in the hospital) or people who are at greater risk of having serious flu complications. Other people with flu illness may also benefit from taking antiviral drugs. These drugs can be given to children and pregnant women.
What are some of the other ways I can protect my child against the flu?
In addition to getting vaccinated, take – and encourage your child to take – everyday steps that can help prevent the spread of germs.
These everyday steps are a good way to reduce your chances of getting all sorts of illnesses, but a yearly flu vaccine is always the best way to specifically prevent the flu.
What should I use for hand washing?
Washing hands with soap and water (for as long as it takes to sing the “Happy Birthday” song twice) will help protect against many germs. If soap and water are not available, use an alcohol-based hand rub.
What can I do if my child gets sick?
Talk to your doctor early if you are worried about your child’s illness.
If your child is 5 years and older and does not have other health problems and gets flu-like symptoms, including a fever and/or cough, consult your doctor as needed and make sure your child gets plenty of rest and drinks enough fluids.
If your child is younger than 5 years (and especially younger than 2 years) or of any age with a long term health condition (like asthma, a neurological condition, or diabetes, for example) and develops flu-like symptoms, they are at risk for serious complications from the flu. Ask a doctor if your child should be examined.
What if my child seems very sick?
Even children who have always been healthy before or had the flu before can get very sick from the flu. Call for emergency care or take your child to a doctor right away if your child of any age has any of the warning or emergency signs below:
Can my child go to school, day care or camp if he or she is sick?
No. Your child should stay home to rest and to avoid giving the flu to other children or caregivers.
When can my child go back to school after having the flu?
Keep your child home from school, day care or camp for at least 24 hours after their fever is gone. (Fever should be gone without the use of a fever-reducing medicine.) A fever is defined as 100°F (37.8°C) or higher.
