A six-year-old child has been frequently having fevers recently. They were hospitalized at a county-level hospital for a week, diagnosed with viral infection with elevated blood counts and slight anemia. They had a fever for three days and then stabilized for four days. A week after discharge, they developed a cough with a fever of 38 degrees. After buying medicine from a traditional Chinese medicine hospital, they discovered the child was having convulsions, with drooping mouth and eyes and vomiting white foam, which lasted for about two minutes before they regained consciousness. The child is currently still hospitalized in a traditional Chinese medicine hospital. Why is the child frequently suffering from throat inflammation and fevers? Is something missing or deficient?
