Poliomyelitis (polio) is a highly infectious and sometimes fatal disease, which invades the nervous system and can cause life-long paralysis. In June 2002, all 53 countries in the WHO European Region were certified polio free. A sustained effort of immunization and disease surveillance helps maintain the Region’s polio-free status and ensures that no polio case can be left undetected.
