The 1918 flu, which ultimately killed about 50 million people globally, likely began in Haskell County, where scientists think the deadly flu virus jumped between animals and humans and then to troops at a nearby army base readying to fight World War I.
Why this matters today was highlighted in a Stat story this week by Helen Branswell, “When Towns Lose Their Newspapers, Disease Detectives are Left Flying Blind.” Continue reading
