The H1N1 Influenza Virus (Swine Flu) is a new strain that appeared in 2009 - a hybrid of swine influenza, avian influenza, and human influenza. Because this is a new strain, a vaccine won't be available until mid-October. Seasonal flu shots do not protect people from H1N1.

All strains of influenza viruses cause contagious respiratory illnesses. Symptoms of influenza are usually mild and similar to the common cold. These viruses occasionally cause more severe respiratory symptoms, particularly in very young children and children with chronic illnesses. For seasonal influenza (human influenza), vaccines are available to help protect against infection. Flu season typically runs from November through April.

Most children will recover from H1N1 influenza with home care. It is not necessary to have your child seen by a physician to confirm a diagnosis of H1N1, and the Centers for Disease Control (CDC) recommend that most healthy children over 5 years of age with mild symptoms do not require treatment with antiviral drugs such as Tamiflu®. If your child is ill with flu-like symptoms (like fever and cough or sore throat) he or she should not go to school or day care and should not visit patients in the hospital. It may be appropriate to reschedule physicians' appointments at Children's Hospital that are unrelated to the current illness.
