Between 25 percent and 50 percent of individuals who have recovered from paralytic polio in childhood can develop additional symptoms decades after recovering from the acute infection, notably new muscle weakness and extreme fatigue.

Around 85 percent of individuals who have recovered from paralytic polio in childhood can develop additional symptoms decades after recovering from the acute infection, notably new muscle weakness and extreme fatigue.

As the PPS indicates that current research gives the higher figure and the older figure is incorrect. 91.154.169.156 (talk) 20:28, 13 May 2025 (UTC)[reply]

What is your reference(s)? This one from 2023 still has "PPS afflicts between 25% and 40% of poliomyelitis survivors and mimics motor neuron diseases (MNDs), such as amyotrophic lateral sclerosis (ALS), due to its selective impairment, degeneration, or death of motor neurons in the brainstem and spinal cord."

This page confuses the meaning behind the three terms, eradication, elimination, and Polio-free. Eradication refers to the global disappearance of a disease and to date. The page incorrectly states that "A majority of countries have successfully eradicated polio." WHO uses the term “polio-free”, which means interruption of wild poliovirus transmission in a region. “Elimination” is a separate concept meaning zero incidence of a disease within a geographic area.

The page also incorrectly states that "In 2000, polio was declared to have been officially eliminated in 37 Western Pacific countries, including China and Australia." when the relevant references clearly state that these countries have been declared "polio-free".

The goal of the Wikipedia:WikiProject Medicine/Vital Signs 2026 campaign is to bring all 101 top-importance articles—including this one—up to at least B-class quality. Many of these articles are widely read but overdue for review, so even small improvements can have a big impact.

If you watch or edit this article, your help would be very welcome. You can:

1. Add yourself as a participant
2. Note the state of the article in the Progress table (is the current class still correct?)
3. Update the article based on recent clinical guidelines and review papers
4. Help address gaps, improve clarity for a broad audience, or improve image selection

To reach B class, articles should have: suitable referencing, reasonable coverage, a clear structure, good prose, helpful illustrations, and be understandable to a broad audience. Contributions of any size are appreciated. Femke (talk) 16:00, 20 December 2025 (UTC)[reply]
