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.

Why does polio affect the legs?

These nerve cells cannot regenerate, and the affected muscles lose their function due to a lack of nervous enervation – a condition known as acute flaccid paralysis (AFP). Typically, in patients with poliomyelitis muscles of the legs are affected more often than the arm muscles.

What stopped the spread of polio?

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.

How long do polio survivors live?

For years, most polio survivors lived active lives, their memory of polio mainly forgotten, their health status stable. But by the late 1970s, survivors who were 20 or more years past their original diagnosis began noting new problems, including fatigue, pain, breathing or swallowing problems, and additional weakness.

What is the key symptom of polio?

Paralysis is the most severe symptom associated with polio, because it can lead to permanent disability and death. Between 2 and 10 out of 100 people who have paralysis from poliovirus infection die, because the virus affects the muscles that help them breathe.

How long does paralytic polio last?

How Long Does Polio Last? People who have milder polio symptoms usually make a full recovery within 1–2 weeks. People whose symptoms are more severe can be weak or paralyzed for life, and some may die. After recovery, a few people might develop “post-polio syndrome” as long as 30–40 years after their initial illness.

When was polio at its worst?

At its peak in the 1940s and 1950s, polio would paralyze or kill over half a million people worldwide every year.
