What are the warning signs of severe influenza in children that parents should watch for?

Parents should monitor for initial influenza symptoms including fever, muscle aches, and chills. The key warning sign is unusual lethargy - a concerning tiredness where children become difficult to arouse, along with decreased consciousness. These symptoms can indicate serious complications, including brain-related issues from influenza infection. When these warning signs appear, parents should seek immediate medical care through the emergency room or hospital. This prompt action is critical as pediatric hospitalizations and deaths from this flu season are climbing dramatically across the country, with multiple cases reported at major hospitals. Early medical intervention can significantly reduce the risk of serious illness and death from influenza complications.
