Why did polio spread so easily?

The polio virus usually enters the environment in the feces of someone who is infected. In areas with poor sanitation, the virus easily spreads from feces into the water supply, or, by touch, into food. In addition, because polio is so contagious, direct contact with a person infected with the virus can cause polio.

The first polio vaccine, known as inactivated poliovirus vaccine (IPV) or Salk vaccine, was developed in the early 1950s by American physician Jonas Salk. This vaccine contains killed virus and is given by injection. The large-scale use of IPV began in February 1954, when it was administered to American schoolchildren.

What animal did polio come from?

The discovery by Karl Landsteiner and Erwin Popper in 1908 that polio was caused by a virus, a discovery made by inoculating macaque monkeys with an extract of nervous tissue from polio victims that was shown to be free of other infectious agents.
