Polio is a contagious viral illness that can lead to paralysis, making its complete eradication important to protect every child from lifelong disability, a mission recognised each year on World Polio Day. This global observance aims to spread awareness about the dangers of polio and the continued worldwide push to end the disease.The day also serves as a platform for governments, health organisations, and communities to reflect on the progress achieved so far, identify ongoing challenges, and strengthen collective efforts toward a polio-free world. Let’s take a look at when World Polio Day is observed and what this year’s theme focuses on.Why Is World Polio Day Celebrated?World Polio Day, observed every year on October 24, aims to raise global awareness about the importance of eradicating polio and maintaining immunization efforts. Recognized by organizations such as the World Health Organization, Rotary International, and UNICEF, the day celebrates the progress made against polio while highlighting the work still needed to protect children from this potentially life-threatening disease. It brings together governments, communities, educators, and health workers in a shared effort to support a polio-free world, underscoring the power of vaccination and the importance of collective action in public health.World Polio Day: History and OriginWorld Polio Day was created to honor Dr. Jonas Salk, who developed the first effective poliomyelitis vaccine. The observance was officially initiated by Rotary International and is now supported by the Global Polio Eradication Initiative (GPEI), which includes key partners like WHO and UNICEF. The day not only commemorates vaccine breakthroughs but also continues the global fight to end polio, a disease that once paralyzed hundreds of thousands of children annually. Thanks to worldwide vaccination campaigns, most of the world is now polio-free, though efforts continue in regions where the virus still exists.World Polio Day 2025 ThemeThis year’s theme, End Polio: Every Child, Every Vaccine, Everywhere, emphasizes the urgent need to vaccinate every child and ensure equal access to protection against polio. It is a call to action for global eradication, highlighting both the responsibility and commitment required to make a polio-free world a reality.How Does Polio Spread?Polio is mainly transmitted through the faecal-oral route, meaning it spreads when a person consumes food or water contaminated with the virus. It can also spread through close contact with an infected individual. The poliovirus lives in the throat and intestines of those infected, and poor sanitation, unsafe water, and inadequate hygiene greatly increase the risk of transmission, especially in communities with limited access to clean facilities.In severe cases, polio can lead to acute flaccid paralysis, which may affect the diaphragm and throat muscles, making it difficult to breathe or swallow. Since there is no cure for polio, prevention remains the only line of defence. Raising awareness about polio vaccination is therefore essential to protect individuals, especially children, from this potentially life-threatening disease.
