A serum positive for IgM is one in which the IgM antibody titer is ≥1:25 in a single sample.

The outbreak was confirmed to be due to MXV.

Acute-phase sera were collected late.

All sera from patients with rotavirus and astrovirus infections had IgG titers to rNV and rMXV in their acute- and convalescent-phase sera.

NA, not applicable.
