He said: “Regular hand washing is vital both before and after travelling. Use hot water and soap for at least 30 seconds and carry a small tube of hand sanitiser that contains at least 60 per cent alcohol with you to use after travelling on buses or the Tube if you have been touching hard surfaces such as hand rails.
“It appears that COVID-19 [the strain of coronavirus infecting people] can remain live for up to two hours after contact so think about using cashless payment and avoid holding the escalator rail if safe to do so when on the Underground system.”
