Polio is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle and multiplies in the intestine.
One in 200 infections leads to irreversible paralysis (usually in the legs).
Among those paralysed, 5% to 10% die when their breathing muscles become immobilized.
There is no cure for polio, it can only be prevented by vaccination. Polio vaccine, given multiple times, can protect a child for life.
Today, polio is only routinely transmitted from person to person in three countries - Afghanistan, Nigeria and Pakistan.
Sanofi Pasteur, as a leader in providing both Oral (OPV) and Inactivated injectable (IPV) Polio Vaccines, has been a longstanding partner of the Global Polio Eradication Initiative (GPEI) and WHO for over 20 years. Since 2013, the WHO has recommended that all children receive routinely at least one doses of IPV.
