The source of the polio virus found in sewage samples could be traced back to a single house or street, a health minister has said.
Lord Kamall said ‘world-beating’ tactics learned during the Covid pandemic were being deployed to track down patient zero.
He revealed the investigation will see officials ‘go along the pipes’ to locate where the virus came from.
Positive samples were first detected at a sewage plant in Beckton which covers a population of 4million people in North and East London.
