What is Polio?

Polio, also known as poliomyelitis, is a highly infectious disease caused by the poliovirus. It can cause paralysis, muscle weakness, and even death.

History of Polio

Polio was once a major public health threat, causing widespread outbreaks and epidemics in the early 20th century. In the 1940s and 1950s, polio outbreaks in the United States and Europe were particularly severe, with thousands of cases reported each year.

Symptoms of Polio

The symptoms of polio can vary depending on the severity of the infection. They can include:

• Fever
• Headache
• Sore throat
• Muscle weakness or paralysis
• Stiffness in the neck and back
• Pain or stiffness in the arms and legs

Types of Polio

There are three main types of polio:

• Type 1: This is the most common and most severe type, causing paralysis and death.
• Type 2: This type is less common and typically causes mild symptoms.
• Type 3: This type is also less common and typically causes mild symptoms.

Vaccination

The development of the inactivated poliovirus vaccine (IPV) in the 1950s led to a significant decline in polio cases worldwide. The vaccine is given in a series of injections, typically starting at birth.

Global Eradication Efforts

The World Health Organization (WHO) launched a global eradication campaign in 1988, with the goal of eliminating polio worldwide. While significant progress has been made, polio remains endemic in several countries, including Afghanistan, Pakistan, and Nigeria.

Current Status

According to the WHO, there were 33 reported cases of wild poliovirus in 2020, down from 350,000 cases in 1988. However, the organization still considers polio a public health emergency, citing the ongoing risk of transmission and the need for continued vaccination efforts.

Interesting Facts

• Polio was once known as "infantile paralysis" because it often affected young children.
• The first polio vaccine was developed by Jonas Salk in 1955.
• The global eradication campaign has saved an estimated 10 million people from paralysis and death.
• Polio is still a major concern in some parts of the world, particularly in areas with poor sanitation and limited access to healthcare.
