👉 The Boston Flu, also known as the 1918–1919 influenza pandemic, was a severe global outbreak of the H1N1 influenza virus that caused widespread illness and mortality. Originating in Boston, Massachusetts, in April 1918, the virus rapidly spread across the United States and other parts of the world, infecting an estimated 500 million people, which is about one-third of the global population at the time. The pandemic was particularly deadly due to its high virulence and the fact that it occurred during World War I, when medical resources were strained and populations were already weakened by the war. Symptoms ranged from mild to severe, with many infected experiencing severe respiratory distress, pneumonia, and death. The Boston Flu highlighted the critical importance of public health measures like quarantine, social distancing, and hygiene in controlling pandemics.
