Polio – Everything You Need to Know

Introduction

Polio, which people also call poliomyelitis. It is a virus that causes a very contagious disease known as polio. The poliovirus is responsible for this illness. It mainly affects kids who are under five years old and can lead to paralysis or, in extreme situations, death.

What is Polio?

Polio spreads through contaminated water or food, or when an infected person directly contacts you. The virus targets your nervous system, causing muscle weakness and, in severe situations, paralysis. This disease has no cure, but you can protect yourself from the disease by getting vaccinated.

What is the History of Polio?

Polio existed for thousands of years, and the first outbreak was recorded in ancient Egypt. However, in the late 19th and early 20th centuries. The disease became a significant public health concern, particularly in industrialized countries.

Researchers in the 1950s worked on creating two polio vaccines → the inactivated poliovirus vaccine (IPV) and the oral poliovirus vaccine (OPV). These vaccines were vital in lowering the global polio case count.

In 1988, the WHO initiated the Global Polio Eradication Initiative with the aim of eradicating polio worldwide by the year 2000. Although this initiative made substantial progress. It faced several challenges including → political instability, conflict, and vaccine hesitancy. From a medical perspective, the eradication of polio is of utmost importance because it will not only rescue lives and prevent paralysis, but also yield savings of billions of dollars in healthcare costs.

In the next section, we will discuss the causes and transmission of this disease.

Causes and Transmission of Polio

The poliovirus infects people easily and causes polio, a severe and sometimes deadly disease that affects the nervous system. It spreads through → contaminated food, water, or surfaces, and you can also catch it by coming into contact with the saliva or feces of an infected person.

How Polio Spreads?

Poliovirus spreads primarily through the fecal-oral route. Infected individuals shed the virus in their faeces, which can contaminate food, water, or surfaces. When someone touches their mouth after coming into contact with these contaminated sources, they can contract the virus.

Furthermore, the virus spreads through respiratory secretions such as saliva, and it transmits when someone coughs or sneezes. In some uncommon instances, contact with an infected person’s blood or semen can result in virus transmission.

Risk Factors for Infection

Poliovirus can infect anyone, but certain populations face a higher risk. The highest risk is for unvaccinated individuals, especially young children. People residing in regions with inadequate sanitation and hygiene are also more prone to poliovirus infection.

How to Prevent Polio

The best way to prevent poliovirus infection is by getting vaccinated. Doctors recommend the polio vaccine for all children as part of their regular immunization schedules. It’s safe, effective, and helps protect against the virus.

Besides vaccination, maintaining good hygiene and sanitation can also play a role in preventing the spread of poliovirus. This involves frequently washing hands with soap and water, using a separate toilet for sick individuals, and disposing of faeces properly.

In regions where poliovirus is still present, vaccination campaigns are frequently conducted to boost vaccination rates and stop outbreaks.

Now, let’s move to the symptoms and diagnosis of the disease.

Symptoms and Diagnosis of Polio

The body shows symptoms to tell us that something’s wrong. Symptoms can be mild or severe, causing different types of discomfort or even intense pain. They can appear suddenly or slowly develop over time. Detecting the root cause of symptoms is a crucial aspect of medicine, and a precise diagnosis is vital for choosing the right treatment. In this section, we’ll delve into the fundamentals of symptoms and diagnosis, starting from when symptoms first appear to the diagnostic tools and tests that doctors employ to identify the underlying condition.

Here is an explanation of the symptoms and diagnosis of the disease:

Incubation Period and Progression of Symptoms

The polio virus takes 7 to 14 days to incubate and during this time, it replicates in the throat and intestinal tract. Once the incubation period is over, individuals might encounter flu-like symptoms, including:

• Fever
• Sore throat
• Headache
• Vomiting
• Fatigue

These symptoms can last for a few days and are not specific to polio. In some cases, polio can progress to more severe symptoms, including paralysis.

Common Symptoms of Polio

The most common symptoms of the disease include:

• Fever
• Headache
• Nausea and vomiting
• Stiffness in the neck and back
• Muscle weakness or paralysis
• Loss of reflexes

Paralysis is the most severe symptom of this disease and occurs in about 1 out of every 200 cases. Paralysis can affect the legs, arms, or both and can be permanent in some cases.

Here is an explanation of the diagnosis of this disease.

Diagnosis Through Laboratory Testing and Clinical Observation

Polio is diagnosed through laboratory testing and clinical observation. The virus can be detected in stool samples or throat swabs using a laboratory test called polymerase chain reaction (PCR). Blood tests can also be used to detect antibodies against the virus.

Clinical observation is also important in diagnosing this disease. Doctors will look for symptoms such as muscle weakness or paralysis, loss of reflexes, and stiffness in the neck and back. If polio is suspected, the doctor may order additional tests to confirm the diagnosis.

As we discussed the Causes, transmission, symptoms, and diagnosis, now let’s move to the treatment and management of this disease.

Treatment and Management of Polio

Polio is a viral infection that can cause paralysis, muscle weakness, and other serious complications. While there is no cure for polio, several treatment and management options are available to help manage the symptoms and prevent the spread of the virus.

No Cure for Polio, but Symptoms Can be Managed

Unfortunately, there is no known cure for polio. Once infected with the virus, it can only be managed through supportive care and symptom management. However, with proper care and management, most people with polio can recover from the infection and lead normal, healthy lives.

Supportive Care

One of the most important aspects of managing polio is providing supportive care to help the patient manage their symptoms. This may include providing breathing assistance, such as the use of a ventilator or oxygen therapy, to help the patient breathe more easily. Physical therapy can also help improve muscle strength and mobility, which can be affected by the virus.

Vaccines for Prevention

One of the best ways to manage this disease is through prevention. The polio vaccine is highly effective in preventing the spread of the virus, and it is recommended for all children as part of their routine immunizations. There are two types of polio vaccines available: the oral polio vaccine (OPV) and the inactivated polio vaccine (IPV). Both vaccines are safe and effective, but the choice of which one to use depends on the individual patient’s health status and other factors.

Now, we will discuss the Global Impact and Eradication effect of this disease.

Global Impact and Eradication Efforts

Polio, also known as poliomyelitis, is a viral disease that can cause lifelong paralysis, and in some cases, death. The disease mainly affects children under the age of 5, and it spreads through contaminated food, water, or contact with infected faeces. Polio epidemics have occurred throughout history, causing widespread panic and devastation.

Current Status of Polio and Global Eradication Efforts

Today, polio remains endemic in only two countries: Afghanistan and Pakistan. However, the disease can easily spread across borders, making global eradication efforts crucial. The Global Polio Eradication Initiative (GPEI), launched in 1988, aims to eradicate this disease globally through vaccination campaigns, surveillance, and outbreak response.

Challenges to Eradication

Despite the progress made toward polio eradication, challenges remain. One major obstacle is vaccine hesitancy, which is the reluctance or refusal to vaccinate despite the availability of vaccines. This can be due to misinformation, lack of trust in vaccines, or religious or cultural beliefs.

Political instability and conflict can also hinder eradication efforts, as they can disrupt vaccination campaigns and surveillance activities.

Final Words on Polio

Polio, or poliomyelitis, affects young children and spreads easily through contaminated food, water, or contact with infected faeces. The virus causes paralysis, which can be permanent, and in some cases, it leads to death. Although there is no cure for this disease, vaccination effectively prevents the disease.

Vaccination and global health efforts play a crucial role in combating polio. Widespread vaccination campaigns have significantly decreased the incidence of this disease in recent decades. In 1988, experts estimated 350,000 cases of this disease globally, but in 2020, only 140 cases were reported, marking a 99.9% reduction. Healthcare professionals and organizations worldwide have tirelessly worked together, achieving this progress through global collaboration.

However, even though we have made progress, we haven’t completely won the battle against this disease. Some parts of the world still have the disease, and if we don’t keep up with vaccinations, new outbreaks might happen. That’s why we need to keep supporting and investing in global health initiatives to get rid of polio forever. If we work together, we can make sure that future generations don’t have to worry about polio or other diseases that can be prevented.
