Symptoms of influenza B pneumonia in newborns

Symptoms of influenza B pneumonia in newborns typically include fever, cough, rapid breathing, difficulty breathing, as well as possible wheezing and wet rales in the lungs. Additionally, due to their immature immune systems, newborns may exhibit non-specific symptoms such as lethargy, poor appetite, and weight loss. Once these symptoms appear, parents should seek immediate medical attention to avoid treatment delays that could affect the newborn's health.
