Patient's question:
Is the red blister near the mouth hand, foot, and mouth disease?Doctor's answer:
Hand, foot, and mouth disease is a common and highly prevalent infectious disease, primarily affecting infants and young children. It can be caused by various enteroviruses, with EV71 being one of them. The disease occurs throughout the year, with peak incidence from May to July. Generally, the symptoms are mild, and most patients first develop fever. Small red spots and blisters appear on the palms and soles (with redness around the blisters), and blisters or ulcers may develop in the mouth, causing significant pain. Some patients may also experience coughing, runny nose, loss of appetite, nausea, vomiting, and headaches. In a small number of cases, the disease can be severe, leading to complications such as encephalitis, meningitis, myocarditis, and pneumonia. If not treated promptly, it can be life-threatening.
