Question
After five days of intravenous treatment for hand, foot, and mouth disease, there has been no improvement. The patient had previously recovered but has now developed blisters again. What could be the reason?
Answer
Hand, foot, and mouth disease is an infectious disease caused by enteroviruses, commonly occurring in children under the age of 5. The main symptoms include the appearance of blisters on the hands, feet, and mouth, with severe cases potentially leading to complications such as myocarditis, pulmonary edema, or aseptic meningitis. The disease is highly contagious and those infected may experience significant symptoms with higher risks. Transmission routes include contact transmission, droplet transmission, and foodborne transmission. The recurrence after treatment may be related to the virus not being completely cleared or the immune system not yet fully established to resist the infection. It is recommended to consult a doctor for individualized diagnosis and treatment advice.
