Poliovirus has caused epidemics for centuries, with major outbreaks in the early 20th century leading to widespread paralysis and fear. The development of effective vaccines by Jonas Salk (inactivated) and Albert Sabin (oral) in the 1950s revolutionized public health, dramatically reducing its incidence and leading to global eradication efforts.
Poliovirus primarily spreads through the fecal-oral route, typically by ingesting food or water contaminated with the feces of an infected person. It can also spread through close contact with an infected individual, though respiratory droplet transmission is less common.
