Avian flu is infecting cows across the US via cow-to-cow transmission. Here's what you need to know about the bird flu spread.

A strain of bird flu known as H5N1 or highly pathogenic avian influenza has made a worrying leap to cattle herds across the US over the past month. This development has sparked “enormous concern” among health experts, including the World Health Organization’s (WHO) chief scientist, who warned of the virus’ “extremely high” mortality rate in humans.

    I dunno about 50%, but Native Americans had a >90% mortality from European disease at the time of the Columbian Exchange, and it messed them up pretty badly.

    The Black Death killed maybe 50% of Europe’s population.

    The Black Death was the second great natural disaster to strike Europe during the Late Middle Ages (the first one being the Great Famine of 1315–1317) and is estimated to have killed 30% to 60% of the European population, as well as approximately 33% of the population of the Middle East.

    That didn’t end European civilization, but it was a cataclysmic event, left huge scars.

    Though they also had shorter supply chains and such, were maybe more-resilient to disruption.

      It’s a matter of being different societies, occurring over different lengths of time, and being global instead of regional.
