Of 29 probable cases, 25 were confirmed, giving an average annual incidence rate of 7.3 per 100 000 in children 0–5 years.The mean age of all cases was 38 months (range: 3.5–80 months).There was a male predominance.The mean time between the onset of illness and diagnosis was 8.2 ± 3.1 days. Five of the 25 patients had cardiovascu- lar abnormalities before treatment. All patients were treated with intravenous immunoglobulin and 22 (88%) responded to a single dose of treatment and high doses of acetylsalicylic acid; 2 patients needed a second dose of IVIG, and 1 patient required a third. Complete recovery was noted in all patients except for 1, who is under follow-up and treatment.
