Patients with hand, foot, and mouth disease may develop brainstem encephalitis, which can lead to lung edema. In severe cases, it may cause respiratory failure, posing a serious threat to life. It is recommended that patients be hospitalized and treated as soon as possible, wishing for a quick recovery.

When pediatric pneumonia leads to lung edema, it is advisable to use antibiotic medications and ensure adequate rest and warmth to prevent the deterioration of the condition.
