Dr. Li Jingli
After a child's temperature returns to normal following influenza B, the recurrence of high fever may indicate that the virus has not been completely cleared from the body, leading to a relapse. Following influenza B infection, the child's immune system continues to fight the virus, which can cause fluctuations in body temperature. If the high fever persists, it may be due to active viral replication, weakened immunity, or other complications. Parents are advised to closely monitor their child's condition, seek medical attention promptly, follow the doctor's treatment recommendations, and provide proper care and nutritional support.
