What are the symptoms of hand, foot, and mouth disease?

Patient's question:

My child has been running a fever recently and has developed many pimples on their body. We suspect it might be hand, foot, and mouth disease. I want to know what are the symptoms of hand, foot, and mouth disease?

Doctor's answer:

The common symptoms of hand, foot, and mouth disease are as follows: Most children suddenly develop the illness. First, they have a low fever, with a temperature below 38 degrees Celsius, accompanied by symptoms such as headache, cough, and runny nose. The temperature remains constant. The higher the fever, the longer the duration of the illness and the more severe the condition. Children with fever may develop blisters on their oral mucosa and lips either during the fever or 1-2 days after it. These blisters burst to form ulcers, causing pain. Children often show signs of discomfort, such as hitting, crying, drooling, and loss of appetite. One to two days after the oral blisters appear, children may develop macules and papules on their palms, soles, and buttocks, mostly on the soles. The blisters are round or oval-shaped, flat, small like rice grains, or large like peas. They are hard with a red halo around them, containing cloudy fluid.
