Common symptoms of the hoof and mouth virus in children include a sore throat and fever accompanied by a red rash that may produce painful, blister-like lesions on the inside of the cheeks, gums and tongue, according to the Mayo Clinic. Some children with the virus may also become irritable.
Many children lose their appetites when suffering from hoof and mouth virus, also known as hand-foot-and-mouth disease, explains the Mayo Clinic. A general feeling of malaise commonly occurs, and some children may develop blisters on their feet.
Children typically develop symptoms of the virus within three to six days, with a fever developing first, notes the Mayo Clinic. Malaise, poor appetites and sore throats usually follow within a day. Painful sores on the mouth, throat, feet and legs or a rash on the hands and feet typically occur one or two days after a fever develops in children affected by the virus.
The viral infection is mild, but it is contagious, explains the Mayo Clinic. The disorder is a result of coxsackievirus and does not require a specific treatment. Physicians commonly treat the symptoms of the disorder and promote good hygiene practices to prevent catching or spreading the hoof and mouth virus.
