Enteroviral infections– Herpangina

• Lesions develop on the mucous membranes, most often on the tonsils, uvula, and soft palate of the mouth • Lesions are characterised by grey-white tiny papulovesicles about 1-2mm in diameter • Lesions are self-limiting and resolve over 5-10 days • Generalised symptoms include high fever, headache, sore throat, difficulty swallowing, vomiting and abdominal pain • Hand-foot-and-mouth • Oral lesions develop anywhere inside the mouth but most frequently appear on the hard palate, tongue, cheek and gums • Oral lesions begin as erythematous macules and papules (flat, inflamed red spots) 2-8mm the hain diameter. These progress to form

thin-walled vesicles (blisters) that burst and form painful ulcers surrounded by a red halo. These heal without treatment over 5-10 days. • Skin lesions appear along with or shortly after oral lesions develop. There may be a few lesions or more than 100 lesions and occur on

nds and the feet. • Skin lesions begin as erythematous macules or papules which quickly turn into small, grey vesicles surrounded by a red halo. These

lesions resolve spontaneously over 7-10 days without scarring. • Boston exanthem disease • After a short fever, pink macules and papules suddenly erupt on the face, trunk, and less commonly the extremities. Small ulcers may

also be found on the soft palate and tonsils. • Eruptive pseudoangiomatosis • Lesions, usually no more than 10, develop on the face, trunk and extremities. Lesions are 2-4mm in diameter and red papules

resembling cherry angiomas. • Lesions resolve spontaneously within 10 days.
