To accomplish this, the authors used RNA fragments of the virus obtained from the bodies of the formerly described 21-year-old Fort Jackson service member, “Lucy” from Brevik Mission, and a third person, a 30-year-old male service member stationed at Camp Upton, New York. gradually do the anomalies become visible as such.

Such an event would require significant increases in the manufacture, distribution and supply of medications, products and life-saving medical equipment, such as mechanical ventilators.

The authors found that the NA gene of the 1918 virus shared many sequence and structural characteristics with both mammalian and avian influenza virus strains.Overall, the phylogenetic analysis seemed to indicate that the ultimate source of the 1918 virus’ NA was avian in nature, but the authors couldn’t determine the pathway from its avian source to the virus’ final pandemic form.
