Based on the HA cleavage site motif and supported by the intravenous pathogenicity index, 2 H7N3 viruses from 1 house in South Carolina were considered to be HPAIV. Bird flu is caused by a type of influenza virus that rarely infects humans. Citing the bird-based Spanish Flu outbreak of 1920, and the H5N1 outbreak in Hong Kong in 1997, Gregor writes, “the worry is that the virus never stands still but is always mutating.
