Was polio not eradicated? Why is polio resurgence?

According to the Centers for Disease Control and Prevention (CDC) For example, polio infections peaked in the United States in 1952, with more than 21,000 cases causing paralysis. The first polio vaccine was introduced in the United States in 1955, and the vaccine was very successful.

We have not seen a case of polio spreading in the Western Hemisphere since 1991, despite a few imported cases. With Immunization rates have declined in the U.S. and around the world due to the pandemic. In many parts of the world, polio remains a threat and children are not vaccinated.

What are the symptoms of polio?

Polio is a viral infection. Most polio cases have no symptoms at all, or very mild symptoms, including fever, headache, and nausea, that go away after a few days.

A small number of cases, maybe 3% or 4%, may progress and lead to meningitis, which is the lining of the brain inflammation. Meningitis can be very scary, but this type of meningitis is usually well tolerated and most people recover.

However, in less than 1% of cases, polio causes paralysis. It infects parts of the spinal cord, specific cells of the spinal cord that control our movement. If these cells become infected, it can cause paralysis in various parts of the body. According to the World Health Organization, 1 in 200 infections result in irreversible paralysis.

It can cause mild fever and irritation (pain, redness and swelling at the injection site).
