2.5-year-old infant, fever for two days, red granules in the throat, no red spots on hands and feet

Patient's question:

Fever above 38 degrees for two days, hoarse voice

Doctor's answer:

Hand, foot, and mouth disease is an infectious disease caused by enteroviruses, primarily affecting infants and young children. It can cause blisters on the hands, feet, and mouth, and in some cases, lead to complications such as myocarditis, pulmonary edema, and aseptic meningitis and encephalitis. The disease is widely distributed, with no significant regional patterns, and can occur in all seasons, peaking in summer and autumn. This condition often presents as outbreaks followed by scattered cases. During outbreaks, kindergartens and daycare centers are prone to collective infections, while families may also experience clustered cases. The disease is highly contagious with complex transmission routes, capable of causing large-scale outbreaks in a short period.
