...This flu, never before seen by scientists,...

Oh, bull. The 1918 "Spanish" Influenza was type A, H1N1. This has been proven by the CDC, Stanford, and other labs.

In stark contrast to contemporary human influenza H1N1 viruses, the 1918 pandemic virus had the ability to replicate in the absence of trypsin, caused death in mice and embryonated chicken eggs, and displayed a high-growth phenotype in human bronchial epithelial cells. Moreover, the coordinated expression of the 1918 virus genes most certainly confers the unique high-virulence phenotype observed with this pandemic virus.
