The 1918 Flu Pandemic
Even in spite of the advancements made in the field of medicine and proper sanitation, the 20th century still wasn’t safe from another virulent menace on the horizon. Documented as one of the most widespread and catastrophic diseases in all of human history, the 1918 flu pandemic infected 500 million people across the globe, leaving 50 to 100 million dead in its wake. Those perfectly fit and healthy weren’t spared from the effects of the H1N1 influenza, necessitating the need for face masks to be worn in public to curtail the flu’s advancement. Researchers debate its origin, but many agree overseas troop deployment across World War I Europe exacerbated the situation.
