*Values are no. (%) except as indicated. p values were obtained from 2-sided t-tests. HAdV, human adenovirus; NA, not applicable. †One student was HAdV positive in March, then had recurrent symptoms in early May and was found to be both HAdV and parainfluenza 3 positive. The student was included in the HAdV infection only column and not in the co-detection column. This student’s clinical course and timeline were more consistent with a new parainfluenza infection; the detection of adenovirus was likely attributable to prolonged virus DNA shedding, not a new infection. This group does not include students with Epstein-Barr virus or group A Streptococcus infections.
