What is Polio?
Polio (poliomyelitis) is a viral infection that can affect the nervous system, in rare cases causing paralysis. It spreads mainly through contact with the faeces of an infected person, or less commonly through contaminated food or water.
Thanks to widespread vaccination, polio has become rare in most parts of the world, though it remains a risk in certain regions. Most infections cause mild or no symptoms, but a small proportion of cases can lead to serious, permanent complications.

Clinical context
Self-care advice
Speak to your GP or a travel health clinic to check your polio vaccination status before travelling to at-risk regions.
03 · Act
When to see a doctor
- 1You're planning travel to a region where polio is still present and want vaccination advice
- 2You're unsure whether your polio vaccinations are up to date
- 3You develop sudden muscle weakness or paralysis, particularly after travel to an at-risk area
- 4You have concerns about a child's polio vaccination schedule
- 5You experienced polio in the past and are noticing new muscle weakness or fatigue (post-polio syndrome)

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Stay up to date with vaccination.The polio vaccine, given as part of routine childhood immunisation, is highly effective at preventing the disease.
- 2Check travel vaccination requirements.If travelling to an area where polio is still circulating, check whether a booster dose is recommended.
- 3Practise good hygiene.Thorough handwashing, particularly around food preparation, helps reduce the spread of poliovirus in affected regions.
- 4Seek urgent care for sudden weakness.Sudden onset of muscle weakness, especially after potential exposure, needs immediate medical assessment.

BarnMD Bottom Line
Vaccination has made polio rare, and keeping vaccinations up to date, especially before travel to at-risk areas, remains the best protection.
If travelling somewhere polio is still present, checking your vaccination status well in advance of your trip is worthwhile.
