What should I do if my 15-month-old baby has influenza B?

General treatment methods for a 15-month-old baby with influenza B include: 1. Daily care: After infection, the baby should get plenty of rest, maintain adequate fluid intake, and stay warm to avoid catching a chill again. 2. Physical therapy: Babies with weaker immune systems may develop high fever. In such cases, physical cooling methods can be used to relieve symptoms, such as applying fever-reducing patches or wiping the body with a lukewarm towel. 3. Western medication: Symptoms following influenza B infection may include fever, coughing, sneezing, and runny nose. If body temperature exceeds 38.5°C, antipyretic medications such as ibuprofen granules or acetaminophen granules may be administered under medical guidance. Additionally, antiviral drugs like oseltamivir phosphate granules should be taken as prescribed by a doctor to prevent progression to severe illness. If the condition becomes serious, prompt medical attention is recommended to avoid delays in treatment.
