*d, days postexposure; hMPV, human metapneumovirus genotypes A1, A2, B1, B2; aMPV C, avian metapneumovirus subtype C. |
*d, days postexposure; hMPV, human metapneumovirus genotypes A1, A2, B1, B2; aMPV C, avian metapneumovirus subtype C.
†For the group exposed to hMPV B2, n = 15 because of 1 death (cause unknown) on day 5 postexposure.
‡For the group exposed to hMPV B2, n = 13 because of 1 death (cause unknown) on day 5 postexposure.
