The World Polio Day (WPD) is observed every year by the World Health Organization (WHO) on October 24 to raise awareness about the hazards of the crippling and potentially fatal infectious disease. The day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine against poliomyelitis. There is no cure for this disease, but there are safe and effective vaccines. Polio can be prevented through immunization. Polio vaccine, given multiple times, almost always protects a child for life. The strategy to eradicate polio is therefore based on preventing infection by immunizing every child until transmission stops and the world is polio-free.
