Question
A one-year-and-four-month-old child, after five days of intravenous treatment, has been cured of hand, foot, and mouth disease. However, the child developed a fever again the next day, and after a blood test at the hospital, was diagnosed with acute tonsillitis and has been taking the corresponding medication. The following day, the child no longer had a fever. What could be the reason for the low fever and yellow nasal mucus after hand, foot, and mouth disease?
Answer
Hand, foot, and mouth disease is an acute infectious disease caused by enterovirus Coxsackie virus, characterized by fever and rashes in the oral cavity, hands, and feet. It commonly affects children under four years old and peaks in July and August during summer. The main modes of transmission are through respiratory droplets or by touching contaminated toys and unclean hands that enter the mouth. After the treatment of hand, foot, and mouth disease, if low fever and yellow nasal mucus appear, it may be due to symptoms of acute tonsillitis. Acute tonsillitis can cause fever and may persist even after treatment.
