Symptoms of influenza in children include a high-grade fever, extreme fatigue, a headache, body aches and a dry, hacking cough, according to WebMD. Children with influenza may also experience a sore throat, belly pain, vomiting, and chills and shakes.
Symptoms of the flu in children commonly begin abruptly and worsen during the first two or three days, explains WebMD. Influenza develops after infection by influenza viruses, which include types A, B or C. Each type produces similar symptoms, yet types A and B are the most common when it comes to a yearly bout of the flu. Type C generally causes mild and sporadic illnesses.
Influenza is highly contagious and spreads through contact with infected patients, according to WebMD. Individuals with influenza can be contagious up to five to seven days after the onset of symptoms and one day before the onset of symptoms. The virus most commonly spreads through germs resulting from coughing or sneezing, in addition to hand-to-hand contact with infected individuals and objects they have touched, such as doorknobs, remotes and utensils.
Doctors commonly treat children with influenza with ibuprofen or acetaminophen to reduce aches and fever, explains WebMD. Rest and liquids can combat the symptoms of influenza. Medical professionals do not typically prescribe antibiotics because these treatments are not always effective for treating viruses.
