Prime Minister Boris Johnson to unveil alert system – UK developments

A Covid-19 alert system is set to be launched by the government in England to track the virus, Prime Minister Boris Johnson is expected to announce on Sunday.

It is understood the system – with alerts ranging from green (level one) to red (level five) – will be similar to the one used to keep the public informed about the terror threat level.

Speaking from Downing Street Johnson is also expected to unveil a new slogan, telling the public to “stay alert, control the virus, save lives” when he gives a televised address updating the nation on the progress of lockdown measures.

“Stay alert” – which replaces “stay home” was criticised by some ahead of Sunday’s announcement for being vague and unsuitable for tackling transmission of a virus.

Johnson is not expected to provide dates for when the current lockdown restrictions – first announced on 23 March – will change
