Polio was once one of the most feared diseases in the U.S. In the early 1950s, before polio vaccines were available, polio outbreaks caused more than 15,000 cases of paralysis each year.
In the late 1940s, polio outbreaks in the U.S. increased in frequency and size, disabling an average of more than 35,000 people each year. Parents were frightened to let their children go outside, especially in the summer when the virus seemed to peak. Travel and commerce between affected cities were sometimes restricted. Public health officials imposed quarantines (used to separate and restrict the movement of well people who may have been exposed to a contagious disease to see if they become ill) on homes and towns where polio cases were diagnosed.
Thanks to the polio vaccine, dedicated health care professionals, and parents who vaccinate their children on schedule, polio has been eliminated in this country for more than 30 years. This means that there is no year-round transmission of poliovirus in the United States.
Many of us witnessed this miracle during our lifetime. It’s a powerful reminder that vaccines work.
