One of the most interesting thing I have found in researching the virus and the Spanish Flu is this article on the affect of social distancing? https://qz.com/1816060/a-chart-of-the-1918-spanish-flu-shows-why-social-distancing-works/

For baseball fans who like to look at charts and graphs this is a really good study of St Louis and Philadelphia during the 1918 epidemic.

"The extreme measures—now known as social distancing, which is being called for by global health agencies to mitigate the spread of the novel coronavirus—kept per capita flu-related deaths in St. Louis to less than half of those in Philadelphia, according to a 2007 paper in the Proceedings of the National Academy of Sciences."

“I think the critical lesson from both the modeling and the historical work is that the benefits of multiple interventions are greatest if they are introduced early (before 1% of the population is infected) and maintained,” wrote Hatchett, who has also directed medical preparedness in the Obama White House."

The history channel describes a very similar tactic to what the states are trying to do now, "The 1918 flu was first observed in Europe, the United States and parts of Asia before swiftly spreading around the world. At the time, there were no effective drugs or vaccines to treat this killer flu strain. Citizens were ordered to wear masks, schools, theaters and businesses were shuttered and bodies piled up in makeshift morgues before the virus ended its deadly global march."

Should we think 2 weeks or a month is going to take care of us, here is another quote from the History.com, "The first wave of the 1918 pandemic occurred in the spring and was generally mild. The sick, who experienced such typical flu symptoms as chills, fever and fatigue, usually recovered after several days, and the number of reported deaths was low.

"However, a second, highly contagious wave of influenza appeared with a vengeance in the fall of that same year. Victims died within hours or days of developing symptoms, their skin turning blue and their lungs filling with fluid that caused them to suffocate. In just one year, 1918, the average life expectancy in America plummeted by a dozen years."

Why was it called Spanish Flu? "By 11 March 1918, the virus had reached Queens, New York. ... The Allies of World War I came to call it the Spanish flu, primarily because the pandemic received greater press attention after it moved from France to Spain in November 1918. Spain was not involved in the war and had not imposed wartime censorship."

So do we assume that once the summer comes and the seasons change that we are done? No. "The second wave of the 1918 pandemic was much deadlier than the first. The first wave had resembled typical flu epidemics; those most at risk were the sick and elderly, while younger, healthier people recovered easily. By August, when the second wave began in France, Sierra Leone, and the United States,[93] the virus had mutated to a much deadlier form. October 1918 was the deadliest month of the whole pandemic."

Sports Illustrated described - "There’s a face mask on the hitter, the bench and the crowd. Underneath their standard equipment, the umpire and catcher have them, too.

"This is how the Pasadena Merchants and Standard-Murphys played a game in the Southern California Winter League on January 26, 1919."

"The 2016 Marlins-Pirates series in Puerto Rico, which was moved to Miami due to Zika virus."

In 1909 " as typhoid fever spread in California, the San Francisco Examiner ran the front-page headline “Epidemic Threatens to Ruin Ball Team” as the Pacific Coast League saw several players fall sick at once. The illness-related charity games have evolved with the times, too: The St. Louis Cardinals had an annual “Tuberculosis Day” game for more than two decades, and years later, President Eisenhower declared “Baseball Polio Day,” when MLB games were used to raise money for the disease on July 4, 1957."

We think of our athletes as men of good health and conditioning, but we have the following list of players who died during their career - only two from flu. https://en.wikipedia.org/wiki/List_of_baseball_players_who_died_during_their_careers

And finally for Twins fans there is this February 20 LA Times article that tells about Brusdar Graterol overcoming the flu - https://www.latimes.com/sports/dodgers/story/2020-02-20/dodgers-brusdar-graterol-over-flu-100-mph-fastball
