Two Ohio schools experienced an outbreak of over 200 cases of chickenpox during the period from October 5 to December 21, 1988, despite adherence to the 1986 American Academy of Pediatrics' recommendation that children be excluded from school for 1 week or until all lesions have crusted.
In grades kindergarten through four, the attack rate for susceptibles was 51% (167/329).
With the use of person-time analysis, classmates of a child with chickenpox in grades kindergarten through four were 3.6 times more likely to become a case 12-17 days (the range of one incubation period) after the last day the child with subsequent chickenpox was in class than at any other time during the 2.5-month study period.
