[1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
Polio eradication, the goal of permanent global cessation of circulation of the poliovirus and hence elimination of the poliomyelitis (polio) it causes, is the aim of a multinational public health effort begun in 1988, led by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF) and the Rotary Foundation.

Post-polio syndrome (PPS, poliomyelitis sequelae) is a group of latent symptoms of poliomyelitis (polio), occurring in more than 80% of polio infections. The symptoms are caused by the damaging effects of the viral infection on the nervous system and typically occur 15 to 30 years after an initial acute paralytic attack.
Poliomyelitis, or polio, is a distinctly contagious illness caused by a virus called poliovirus. The virus targets the nervous system, which is why it sometimes triggers spinal and respiratory ...
“The polio vaccine has saved millions of lives and held out the promise of eradicating a terrible disease. Efforts to undermine public confidence in proven cures are not just uninformed – they ...
The discovery that oral antibiotic azithromycin can be used instead of the previous standard, injected penicillin, was tested on Lihir Island from 2013 to 2014; [58] a single oral dose of the macrolide antibiotic reduced disease prevalence from 2.4% to 0.3% at 12 months. [59]
The number of polio cases globally has dropped by more than 99% since the global effort to wipe out the disease led by the World Health Organization and others began in 1988. ... the wild polio ...
The infection is caused by the poliomyelitis virus which is a single-stranded, positive sense RNA virus surrounded by a non-enveloped capsid. Humans are the only known natural hosts of this virus. The disease has been eliminated from the U.S. since the mid-twentieth century, but is still found in certain areas of the world such as Africa. [3]
