Traces of polio virus found in London sewage as health officials declare national incident
Officials believe there has been some spread between closely linked individuals in northeast London - probably extended family members.

Traces of the polio virus have been found during a routine sewage inspection in London, leading the UK Health Security Agency to declare a national incident.
Health officials are now extremely concerned about the community spread of the virus after samples were collected from the Beckton Sewage Treatment Works in London.
"Jane Clegg, chief nurse for the NHS in London said:"The majority of Londoners are fully protected against polio and won't need to take any further action, but the NHS will begin reaching out to parents of children aged under five in London who are not up to date with their polio vaccinations to invite them to get protected.
