Dr Hilary Jones had a message for parents on Good Morning Britain today. Thursday's edition of the ITV news programme was hosted by Adil Ray and Charlotte Hawkins.
The two were joined by the well-known medical expert who discussed how concerned people should be after polio was detected in the UK. Polio was eradicated in Britain in 2003, but the UK Health Security Agency has found the virus in sewage samples in London, collected from the London Beckton Sewage Treatment Works, which serves around four million people in north and east London.
Experts have raised the alarm after several genetically-linked viruses were found in samples between February and May. However, it is quite normal for the virus to be picked up as isolated cases and not detected again reports the LiverpoolEcho.
