Does hand, foot, and mouth disease caused by doctors cause pulmonary edema?

Patient's question:

A while ago, my nephew didn't know what happened and contracted hand, foot, and mouth disease. Later, he was further examined and found to have pulmonary edema. I don't know if hand, foot, and mouth disease can lead to pulmonary edema, so I guess I should consult a doctor about whether hand, foot, and mouth disease can cause pulmonary edema. Urgent, urgent, urgent

Doctor's answer:

Hand, foot, and mouth disease typically presents with purulent oral mucosa, red rashes on the palms, soles, and buttocks. Severe cases may develop complications, such as second-degree brainstem encephalitis. Brainstem encephalitis can lead to pulmonary edema, which is a serious complication and may progress to respiratory failure, directly threatening the patient's life. It is therefore recommended to seek hospital treatment as early as possible. Wishing you a speedy recovery.
