Chris Whitty says queuing is an outdoor scenario with greater chance of COVID spreading
Risk of transmission much lower outdoors than indoors... but new variant of virus ‘undoubtedly’ increases that risk compared with before
However, Whitty sure jogger running past someone in street is safe
Chris Whitty has warned that queuing outdoors could increase the risk of spreading coronavirus.
The risk of transmission of COVID-19 is well known as being far lower outdoors than indoors.
However, Prof Whitty, making a rare broadcast round of TV and radio stations on Monday, said the new variant of the virus – which has caused record infections, hospitalisations and deaths in recent weeks – “undoubtedly” makes every outdoor situation “slightly more dangerous”.
Describing outdoor scenarios which are of greater risk, England’s chief medical officer told BBC Radio 4’s Today programme: “It’s the much longer contacts in close proximity that can still happen outdoors.

“If people, for example, are crowded together in a queue… if they’re really huddled together around a market stall or something, that is a risk with this virus.”
Prof Whitty, one of Boris Johnson’s top COVID advisers, said there “might be some logic” to people wearing masks in such situations, but he said a “much better” alternative would be to avoid all unnecessary trips outdoors.
However, Prof Whitty dismissed a suggestion that fleeting contact in the street, such as a jogger running past, could be a risk.
“Very short contact like that, outdoors, is extremely low-risk.”
Responding to Prof Whitty’s comments, infectious diseases professor Keith Neal, from the University of Nottingham, said the risk of infection from someone walking or running past “is incredibly low and approaches zero”.
Regarding prolonged queuing, Prof Neal agreed wearing masks “is prudent” – but that increased social distancing would be more effective, and that supermarkets should place two-metre distance markers on the ground.
Elsewhere in Prof Whitty’s broadcast round, meanwhile, he promised life will return to normal… but not for a long time.
All four UK nations are under national lockdowns due to the winter crisis caused by the new variant.
