Polio, short for poliomyelitis, is an infectious viral disease caused by the poliovirus. It primarily affects children under the age of five, but can also impact adults. Polio is highly contagious and spreads mainly through the fecal-oral route, meaning it is transmitted through contaminated food, water, or direct contact with an infected person. The poliovirus attacks the nervous system, specifically the spinal cord and brain, leading to paralysis in severe cases.
Polio has been a major public health concern for decades, causing widespread outbreaks and leaving thousands of children disabled. However, thanks to the development of effective vaccines, the number of polio cases has significantly decreased worldwide. Understanding the causes and transmission of polio is crucial in preventing its spread and protecting ourselves and our communities.
The poliovirus has three distinct types, known as wild poliovirus type 1, 2, and 3. Each type can cause paralysis and has different characteristics. Poliovirus type 1 is the most common and virulent strain, responsible for the majority of polio cases. Type 2 and 3 are less prevalent but can still cause severe illness. Vaccination is the key to preventing polio and eradicating this disease globally.
Polio is caused by the poliovirus, which belongs to the family of enteroviruses. The virus is mainly transmitted through the fecal-oral route, meaning it spreads through contact with infected fecal matter or oral secretions. This can occur when consuming contaminated food or water, or through close contact with an infected person.
The virus enters the body through the mouth and multiplies in the throat and intestines. It then spreads to the bloodstream and can invade the central nervous system, causing paralysis in severe cases. Polio is highly contagious, and even individuals who show no symptoms can spread the virus to others.
Poor sanitation and inadequate hygiene practices contribute to the transmission of polio. In areas with limited access to clean water, proper sanitation facilities, and vaccination programs, the risk of polio outbreaks is higher. It is crucial to emphasize the importance of hygiene, sanitation, and vaccination in preventing the spread of polio.
Polio can present in different ways, ranging from asymptomatic to severe illness. Approximately 95% of polio infections are asymptomatic, meaning individuals do not display any symptoms. However, these individuals can still spread the virus to others, unknowingly contributing to the transmission.
For those who do develop symptoms, it usually starts with flu-like symptoms such as:
These initial symptoms can last for a few days before progressing to more severe manifestations. In some cases, polio can lead to muscle weakness, paralysis, and even death.
The severity of polio depends on various factors, including the individual’s age, immune status, and the type of poliovirus involved. Paralytic polio, the most severe form of the disease, occurs in approximately 1% of polio cases. It can cause permanent muscle weakness, leading to lifelong disabilities.
Vaccination is the most effective way to prevent polio and its devastating consequences. There are two main types of polio vaccines: the inactivated polio vaccine (IPV) and the oral polio vaccine (OPV). Both vaccines provide immunity against the wild poliovirus and contribute to the global eradication efforts.
The IPV is an injectable vaccine made from inactivated or killed polioviruses. It is given as a series of shots, usually administered at 2, 4, and 6-18 months of age, followed by a booster dose during adolescence. The IPV is considered safe and effective, providing long-lasting immunity against polio.
On the other hand, the OPV is an oral vaccine that contains weakened, live polioviruses. It is administered as drops in the mouth and stimulates the immune system to produce a response against the poliovirus. The OPV is primarily used in countries where polio is still endemic, as it can also contribute to the spread of the vaccine-derived polioviruses in rare cases.
The vaccination schedule for polio varies depending on the country and the vaccination guidelines. It is essential to follow the recommended schedule and ensure that you and your loved ones receive the necessary doses of the polio vaccine.

Preventing polio begins with vaccination. Ensuring that you and your loved ones receive the recommended doses of the polio vaccine is essential in protecting against this disease. Vaccination not only provides individual immunity but also contributes to the overall effort to eradicate polio globally.
In addition to vaccination, practicing good hygiene and sanitation measures can help prevent the spread of polio. This includes regular handwashing with soap and clean water, especially before eating or preparing food, and after using the toilet. It is also important to consume safe and clean food and water, avoiding consumption of contaminated items.
For those planning to travel to areas where polio is still endemic, it is crucial to seek pre-travel advice and ensure that all necessary vaccinations are up to date. Taking these preventive measures can significantly reduce the risk of contracting polio and prevent its transmission.
Since the introduction of the polio vaccine, significant progress has been made in eradicating this disease. Global polio eradication efforts, led by organizations such as the World Health Organization (WHO), have resulted in a dramatic reduction in polio cases worldwide.
In 1988, when the Global Polio Eradication Initiative was launched, polio was endemic in 125 countries, with hundreds of thousands of cases reported annually. As of 2021, wild poliovirus transmission is limited to just two countries, Afghanistan and Pakistan. This remarkable achievement is a testament to the power of vaccination and the dedication of healthcare professionals and organizations worldwide.
However, despite the progress made, the fight against polio is not over. Ongoing efforts are needed to ensure that every child receives the polio vaccine, especially in areas where the disease is still endemic. Continued surveillance, vaccination campaigns, and community engagement are crucial in achieving the ultimate goal of global polio eradication.
In conclusion, understanding polio is essential in protecting ourselves, our families, and our communities. By knowing the causes, symptoms, and prevention methods, we can make informed decisions about our health and contribute to the eradication of polio. Vaccination remains the most effective tool in preventing polio, and at Immunize Los Angeles, we are here to support you in your journey towards a polio-free world.
