What really caused polio?
What causes polio.
Polio is caused by the poliovirus.
The virus enters the body through the mouth.
It is spread through contact with the feces (stool) of an infected person or through exposure to phlegm or mucus when an infected person coughs or sneezes..
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.
Can you recover from polio paralysis?
Recovery from minor polio occurs in about three days. The fever and other symptoms of paralytic polio can go away within days, but paralysis can be permanent. Some muscle function may return during the first six months after the acute illness, and improvement can continue for two years.
Can polio affect offspring?
When women had poliomyelitis during a pregnancy, more miscarriages and stillbirths were observed, as was paralysis of the newborn ( congenital polio). The vaccines for polio are made up of inactivated viruses and, if given in pregnancy, do not seem to cause any harm to the developing embryo or fetus.
Can you still get polio if you’ve been vaccinated?
No, thanks to a successful vaccination program, the United States has been polio-free for more than 30 years, but the disease still occurs in other parts of the world. It would only take one person with polio traveling from another country to bring polio back to the United States.
What does Polio do to legs?
Symptoms vary from mild, flu-like symptoms to life-threatening paralysis. In less than 1% of cases, polio causes permanent paralysis of the arms, legs or breathing muscles. Between 5 and 10% of people who develop paralytic polio will die. Physical symptoms may return 15 years or more after the first polio infection.
What percent of polio is paralytic?
About four to five percent of infected people have minor symptoms such as fever, muscle weakness, headache, nausea and vomiting. One to two percent of infected persons develop severe muscle pain and stiffness in the neck and back. Less than one percent of polio cases result in paralysis.
When did they find a cure for polio?
On March 26, 1953, American medical researcher Dr. Jonas Salk announces on a national radio show that he has successfully tested a vaccine against poliomyelitis, the virus that causes the crippling disease of polio.
Can you be cured of polio?
Failure to eradicate polio could result in as many as 200 000 new cases every year, within 10 years, all over the world. There is no cure for polio, it can only be prevented. Polio vaccine, given multiple times, can protect a child for life.
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.
