*Values indicate patient samples/produce samples positive for norovirus (e.g., the GII.3[P7] combination was detected in 2 patient and 4 produce samples). Several VP1 and RdRp combinations are detected in patient and produce samples. Produce samples were obtained from open-air markets near the infection cluster and sent by local health officials for testing to determine a potential norovirus source. ND, not detected; P, polymerase; RdRp, RNA-dependent RNA polymerase; VP, viral protein.
