Understanding Polio: Causes and Effects

In the 1930s and 40s, summer was dreaded in America due to the onset of polio season. Polio, a highly contagious virus, spread through sneezing, coughing, and contact with human waste, though this was not known at the time. The virus attacked the nervous system, leading to paralysis and death, particularly in children. The disease spread silently, causing widespread fear and tragedy. However, efforts by leaders, scientists, and the public eventually led to combating the disease, offering hope for a future free from its grip.
