An emergency vaccination-booster campaign in London last summer reached more than 370,000 children.

And in early November, the latest tests found less of the virus - but officials say there is no room for complacency.

Dr Vanessa Saliba, from the UK Heath Security Agency, told BBC News: "We have early signs that there's less spread of poliovirus in London - but we will need 12 months of no detections before the World Health Organization could declare that the UK is no longer an infected country."
