Polio 101: Signs, Symptoms, Dangers

It attacks children under the age of 5 most strongly, and the worst forms of the virus can cause nerve damage, leading to paralysis, dyspnea, and death. During the 20th century epidemic, the virus frequently occurred during the warm summer months and struck towns and cities every year or so.

Polio was one of the most feared illnesses in the world until he was a doctor. Jonas Salk invented the polio vaccine in 1954 and tested its safety.

“In the early 1950s, before the polio vaccine became available, polio outbreaks caused more than 15,000 paralysis each year,” the United States said. Centers for Disease Control and Prevention OK. “Parents were afraid to let their children out, especially in the summer when the virus seemed to peak.”

What Causes Polio?

Enteroviruses, called polioviruses, cause polio.According to, there are three strains, two of which are eliminated in the world World Polio Eradication InitiativeWHO program.

However, one type of wild poliovirus is still endemic in Pakistan and Afghanistan and can be picked up by travelers and transported around the world. “Only one traveler with polio can bring the disease to the United States,” the CDC said.

Infection can also occur if not enough children are vaccinated in an area. It usually occurs with the oral polio vaccine first used in 1961, created by Dr. Albert Sabin. According to GPEI, the formulation of this vaccine contains a mixture of each of the three live attenuated poliovirus strains.

Poliovirus confirmed in London sewers, says British health agency

“The weakened strain can be flushed into the environment through the digestive system by vaccinated children and transferred from an unvaccinated individual to another. This process is inadequate. It is exacerbated by a good sanitary system and lack of clean drinking water, “GPEI said.

When a strain infects an unvaccinated person, it begins to circulate and can travel around the world.

It may be a factor in the recent diagnosis of polio in Rockland County, New York. First case of polio in the United States since 2013According to the New York State Department of Health.
Tests confirmed by the CDC have found a type of virus that appears to have come from people who have been vaccinated with “oral polio vaccine (OPV), which is no longer licensed or administered in the United States.” Health Department said in a statement..

“This suggests that the virus may have originated outside the United States where OPV is being administered, as the (reverted) strain cannot emerge from the inactivated vaccine.” Said the statement.

Commonly used by healthcare professionals around the world Various types of oral vaccines Fighting polio is cheap, easy to manage, safe, effective, and provides long-term protection. However, Salk’s original inactivated polio vaccine is Manage through a series of childhood shotsThe only version used in the United States since 2000. CDC said..

Polio is highly contagious

According to CDC data, vaccination rates for kindergarten children fell last year.
Poliovirus lives in the throat and intestines of infected people. People who carry poliovirus, including asymptomatic people, can spread the highly contagious virus in their faeces for several weeks.Rarely, virus infection Can occur Through droplets from sneezing and coughing CDC said..

Most people come into contact with polio by picking up small pieces of infected feces and touching them.Exposure to the virus also occurs when you have children Mouth toys or other objects contaminated with feces.

In unsanitary conditions, the virus can also spread through contaminated food and water.

Polio symptoms start like the flu

Many cases of polio, such as Covid-19, are asymptomatic. In fact, according to the CDC, about 95% of all polio cases are asymptomatic.

When symptoms appear, they can take three forms. Flu-like symptoms such as headache, sore throat, nausea, diarrhea, fever, and malaise are characteristic of polio miscarriage.

If these symptoms include additional neurological symptoms such as photosensitivity or stiff shoulders, you may have polio without paralysis.

The most dangerous versions of polio can cause paralysis “in a matter of hours,” WHO said. The disease begins with flu-like symptoms and progresses to muscle aches, cramps, and loss of reflexes. Paralysis on one or the other side may continue.

An iron lung patient at Baltimore Hospital got his first television. Mirrors allow them to watch the broadcast.
Illness can also affect Lungs-When the breathing muscles get stuck, 5% to 10% of people die. According to WHO.. Patients often suffer during epidemics of the 1940s and 1950s Iron lungs to help them breathe.
But the stats show In most cases of paralytic polio, people recover-less than 1% of people with polio are paralyzed, According to GPEI.. Unfortunately, muscle and joint weakness and pain, breathing and swallowing problems, sleep problems, and poor circulation can last a lifetime.virus It hides and goes dormant and may even appear in so-called things a few years later. Post-polio syndromeCDC said.

Treatment of polio

There is no cure for polio, only treatments that relieve symptoms.

“Fever and physiotherapy are used to stimulate muscles, and antispasmodics are given to relax muscles,” GPEI said. “This can improve mobility, but it cannot reverse permanent polio paralysis.”

Vaccination is the only preventative measure.
