The headlines were alarming: 'Highly contagious polio spreading in the UK for the first time in years' and 'Urgent investigations after rare virus detected' are just a couple of examples. Another simply read: 'Polio horror.'
In late June, health officials announced they had picked up poliovirus during routine checks of London sewage water. Analysis suggested the highly contagious bug, which can cause paralysis and lifelong disability, was silently circulating.
Polio, which primarily harms young children, had not been seen in the UK since 1984, following one of the most successful worldwide vaccination campaigns in history.
