In children, the illness is usually self limiting, lasting four to five days, but at least 1% of children under 15 years experience a complication.1 2 These include secondary bacterial infection (particularly with group A beta haemolytic streptococcus),3 pneumonia, encephalitis, haemorrhagic complications, hepatitis, arthritis, and Reye syndrome.4 Furthermore, 10-50% of all children will visit a physician with an infection.5-7 The mortality rate of varicella in children under 14 years in the United States is estimated at 2 per 100 000 cases,8 and 90% of these have no risk factors for severe disease.9
Adults experience only 5% of all varicella cases, but experience more
