*Values are no. (%) except as indicated. EV, enterovirus; IQR, interquartile range. †Two EV-D68–positive household contacts were children and had onset of symptoms starting 2 d before or on the same day as the primary participant. The other 3 EV-D68–positive household contacts were adults and had onset of symptoms that started 3–5 d after the primary participant. ‡Including the primary participant.
