What should you know about source of polio virus?

The virus can multiply in the gut and pass from an infected person in stool. Poor hand hygiene after using the toilet or changing nappies can transfer contamination to surfaces, food or the mouth. Some infections cause no obvious illness, while others begin with fever, tiredness, headache, nausea or muscle discomfort. In a small number of cases, the nervous system is affected and weakness or paralysis can develop. Possible exposure does not by itself confirm illness.

Wash hands carefully with soap and water after using the toilet and before preparing or eating food. Use safe drinking water and food practices, and avoid sharing personal items that may be contaminated. Check that children and adults in the household are up to date with Childhood Immunisation. If travel or a known exposure raises concern, contact a healthcare professional for individual advice rather than relying on symptoms alone.

Seek urgent medical help for new limb weakness, difficulty walking, trouble swallowing, breathing difficulty, severe headache, confusion or rapidly worsening illness. Contact a clinician promptly after a known exposure, especially if fever or unusual weakness develops. Keep the exposure and vaccination history available so the assessment can be targeted.

Ask whether your immunisations are current, whether an exposure changes your vaccination plan, which symptoms need urgent review, and how to reduce infection risk for children and other household members.
