Polio

no.l.........................................
but its patients are decreasing...

The enterovirus poliovirus from the family picornaviridae.

Polio is caused by a virus that attacks the central nervous system and affects the movement of muscles.

Stiffness and paralysis typically occurs in the neck and head.

Jonas Salk

Dr. Jonas Salk invented the vaccine against the polio. Before that the whole world was worried about the polio. Polio used to affect the most precious population, children! Two years before the invention of the polio vaccine, in US alone about 50,000 children got affected by polio. Dr. Jonas Salk did not get the patent for the vaccine, so that the vaccine became affordable for every body. Today is the 100th birth day of this hero. (28th October 2014.)

Jonas Salk invented polio vaccine. He did not patent the vaccine, so that it should be made affordable to every body.

Elizabeth Kenny

Jonas Salk was an American doctor and scientist. He was born in New York City. But if you are asking about his ancestry, his parents were Jewish immigrants, who came to America from Russia. He was the oldest of three sons, and the first in his family to attend college.

She either wanted marsh mellows or that was Shirley but I think she wanted either marshmellows or a hot guy and licorice. . . the hot guy ends up being art pegs brother.. hahaha (: hoped it helped. personally, I thought it was a really good book and recommend it to kids ages 11+.

Everywhere, but did not exhibit in epidemics until late 1800s after cities were cleaned up enough that children under 4 no longer were regularly exposed and naturally acquire lifetime immunity (in children under 4 the disease usually manifests in a milder nonparalytic form, in teens and adults the disease is much more severe and more likely to paralyze). Without natural immunity, when large enough groups of teens and adults accumulated the virus could spread like wildfire resulting in epidemics and serious symptoms.

Now it is 1 in a million as of 2020. In the early 20th century, polio was one of the most feared diseases in industrialized countries, paralyzing hundreds of thousands of children every year. Soon after the introduction of effective vaccines in the 1950s and 1960s however, polio was brought under control and practically eliminated as a public health problem. More people feared polio than the atomic bomb.

In the 1950s, Salk developed the first polio vaccine, an injection.

In 1962, Sabin developed the oral polio vaccine, taken by mouth, and still used, at present.

It is not given in intervals. It is given during childhood and the shot lasts forever.

I remember both the injected Salk and oral Sabin multiple times in grade school in the 1960s. They seemed to think multiple applications were needed then.

That is unknown. When it was an acute illness and millions were dying from it, it was thought that it only affected some people like a cold. Vaccination has gotten rid of it in all except Muslim countries.

The organism that causes polio is a virus.

India to be polio free.

The oral polio vaccine is a live virus that is mutated in order for it to be strong enough to induce an immune response but weak enough to not cause disease. This replication in the host of the live virus gave a better immune response and also allowed the vaccine strain to spread and inoculate people who did not directly (intentionally) received the disease. The problem is that rarely it could "back mutate" and actually produce polio disease.

It is believed that when the oral polio vaccine was widely used in the US there were about 10 cases per year of vaccine induced polio (compared to thousands of cases per year of natural polio before the vaccine was developed). Some studies cast doubt on this number by carefully examining proposed cases and finding other causes in most of them.

When the polio incidence became nearly zero it was decided that the advantaged of increased immunity and increased spread of the oral vaccine were not worth the vaccine induced cases and so the US, and most developed countries, switched to the injectable vaccine.

Polio is not curable at the last stage.... it can only be prevented and not cured.

0 he wanted to help the world while he did not patan it

Polio has no size, It's a disease.

pa ans. ans ko pa gaga

It was named after the virus that causes the disease.

It is not recommended to have food or drink for thirty minutes after receiving the Oral Polio Drops. This is recommended to allow time for the vaccine to reach the system without being diluted by food or drink in the stomach.
