Do White Blisters on the Hands and Feet Indicate Hand, Foot, and Mouth Disease?

Question

The patient has two white blisters on their hands and feet, the size of mung beans, accompanied by a runny nose, but no fever and a good mental state. Are these symptoms enough to diagnose hand, foot, and mouth disease?

Answer

The typical symptoms of hand, foot, and mouth disease include fever, red blisters in the mouth, followed by blisters on the hands, feet, and buttocks. The presence of foot symptoms alone is not sufficient to diagnose hand, foot, and mouth disease. Hand, foot, and mouth disease is more common in children due to their lower resistance to bacteria. However, after infection, they can develop immunity to the bacteria.
