In a statement released today, he revealed new measures may soon be required to contain the outbreak. He said: “The Prime Minister has said that we are now seeing the start of a second wave of Covid-19 across the UK. “Londoners should also know that I am extremely concerned by the latest evidence I’ve seen today from public health experts about the accelerating speed at which Covid-19 is now spreading here in London.
“This is made worse by the uncertainty caused by the lack of testing capacity in the capital.
“It is increasingly likely that, in London, additional measures will soon be required to slow the spread of the virus.
“We will be considering some of the measures which have already been imposed in other parts of the UK.”
He also urged Londoners to be cautious and maintain social distancing measures where possible.
The Mayor made the announcement after meeting with Public Health England officials, London council leaders and the Government about the rise in cases.
Aside from the East Midlands, the North West and the North East, London has the highest infection rate per 100,000 in the population.
As cases surge, London is now registering 497.1 per 100,000.
Multiple areas in the North West and the North East have been placed into lockdowns due to the rise in coronavirus cases.
The public may also be advised to avoid public transport while households will not be able to mix.
Fears of a second wave in the capital comes as the Prime Minister warned a second wave is now “inevitable”.
Speaking today, he said the Government would review measures but ultimately, a second wave of the virus will soon hit the UK.
He said: “We are now seeing a second wave coming in.
“It is absolutely, I’m afraid, inevitable, that we will see it in this country.”
Mr Johnson said this as case numbers have risen to levels not seen since May.
The UK recorded 4,322 cases today, the highest daily rise since May 8.
Scientists have all expressed concern after the infection rate has now been estimated between 1.1-1.4.
