  • The phylogenetic results, combined with these other lines of evidence, suggest that the high mortality in 1918 among adults aged ∼20 to ∼40 y may have been due primarily to their childhood exposure to a doubly heterosubtypic putative H3N8 virus, which we estimate circulated from ∼1889–1900. All other age groups (except immunologically naive infants) were likely partially protected by childhood exposure to N1 and/or H1-related antigens.

    The Spanish flu apparently had the N1 complex present, to which the 20-40y population wasn’t exposed. At least that’s my limited understanding after skimming the paper.






  • In Germany we have got an integrated system with small pockets of protected forest inside leger forests. However, in opposition to most of the world, we don’t do clear cuts or the like, except for big calamities. we would usually fell single trees inside a forest and have the others left over for a later date or generations. You can get a year old sapling next to a 300 year old oak and everything in between right next to each other. Naturally due to historical over use, we haven’t got any old growth forests like in Ukraine or Poland, but we certainly preserve our ecological functions.
