At present’s Seasonal Flu Might Descend From 1918 Pandemic Pressure | Well being & Health

TUESDAY, Might 10, 2022 (HealthDay Information) — The present H1N1 flu, generally generally known as the swine flu – seems to be a direct descendant of the influenza virus that induced the catastrophic 1918 pandemic, a brand new evaluation reveals.

Genetic knowledge extracted from samples of the 1918 flu not too long ago found in Germany counsel that every one the genome segments of the seasonal H1N1 flu may very well be immediately descended from that preliminary horrible pressure, the researchers stated.

“The next seasonal flu virus that continued to flow into after the pandemic might properly have advanced immediately from the pandemic virus fully,” stated lead researcher Sebastien Calvignac-Spencer, an evolutionary biologist on the Robert Koch Institute in Berlin.

If right, this new concept contradicts different hypotheses which have held that the present seasonal flu arose by completely different viruses that shared their genetic code, the research authors famous.

This studio It started when Calvignac-Spencer and her colleagues found a uncommon set of lung tissue samples dated between 1900 and 1931, all stored on the Berlin Museum of Medical Historical past and the Pure Historical past Museum in Vienna, Austria.

From these lung samples, the researchers had been in a position to develop a whole flu genome from a pattern collected in Munich in 1918, in addition to two partial flu genomes collected in Berlin that very same yr.
