Importance of World Polio Day
Polio (Poliomyelitis) is a highly viral infectious disease, mainly affecting children under five. The virus is spread from person to person, mainly through the faecal-oral pathway or, less frequently, by a shared object (such as contaminated food or water). It multiplies in the intestine, from where it can enter the nervous system and cause paralysis.
There are cases of paralytic poliomyelitis due to a loss of viral attenuation in the oral polio vaccine (OPV), known as vaccine-associated paralytic poliovirus (VAPP). Vaccine-associated paralytic poliovirus (VAPP) is very rare, occurring approximately 3.8 times per lakhs of cases in countries using the oral poliovirus vaccine.
Over the past 35 years, cases of wild poliovirus have decreased by more than 99%, from 3,50,000 cases per year to less than ten annual cases of wild polio. 80% of variant polio cases are in only four subnational regions.
Polio is a highly contagious disease affected by the polio virus. Although very rare, the virus may damage the parts of the brain, which can cause death. World Polio Day was established to eradicate polio worldwide and to ensure a polio-free future for everyone, develop high immunisation coverage, implement high-quality observation to detect any presence of the virus and plan for an outbreak response.

In 1955, he created the Inactivated Poliovirus Vaccine. In 1962, Albert Sabin created the Oral Polio Vaccine. In 1988, World Health Assembly committed to eradicate the poliovirus, at the time, there were around 3,50,000 cases worldwide. In 2002, WHO European Region was declared polio-free since then on October 24, the World Polio Day is celebrated worldwide.
