The United Kingdom has the world's second-highest official COVID-19 death toll and, after criticism that he was slow to impose a lockdown, Johnson is extremely wary of triggering a second deadly wave of infection.
"Our plan must countenance a situation where we are in this, together, for the long haul, even while doing all we can to avoid that outcome," Johnson said in a foreward to the 51-page "Our Plan to Rebuild: The UK Government’s COVID-19 recovery strategy."
"It is likely that COVID-19 will circulate in the human population long-term, possibly causing periodic epidemics," the plan said. "In the near future, large epidemic waves cannot be excluded without continuing some measures."
The plan includes a staged undertaking to allow businesses to reopen, advice on avoiding public transport and wearing face coverings as well as an 14-day quarantine for most international arrivals.
There was a lack of specific detail, though, on what employers should do to ensure the safety of workers. The leaders of Scotland, Wales and Northern Ireland said they were sticking with the existing "stay-at-home" message.
Opposition parties said his "Stay Alert" message was meaningless against a virus invisible to the naked eye and that Johnson's messaging was confusing. Lawyers said some employers were confused about who should be working and when.
'FACE COVERING'
After weeks of declining to tell the British people to wear face coverings amid contradictory scientific advice on the utility of such masks, the government said face coverings should be worn in enclosed spaces where distancing is impossible.
"Homemade cloth face-coverings can help reduce the risk of transmission in some circumstances," the plan said. "Face-coverings are not intended to help the wearer, but to protect against inadvertent transmission of the disease to others if you have it asymptomatically."
Public Health England even published an accompanying description on how to make a face covering from an old T-shirt, along with cutting advice and how to sew a homemade face covering. It said a sewing machine was optional. https://www.gov.uk/government/publications/how-to-wear-and-make-a-cloth-face-covering/how-to-wear-and-make-a-cloth-face-covering
Opposition Labour Party leader Keir Starmer said Johnson's presentation had raised many questions and was perplexing.
"It's a bit all over the place," Starmer said.
Trade union leader Len McCluskey said Johnson had confused people. "Millions of people this morning will be completely dumbfounded," McCluskey said.
Scottish First Minister Nicola Sturgeon said the only modification she was making to lockdown measures was to allow people to exercise more.
Johnson's stern address to the nation prompted satire.
"So we are saying don’t go to work, go to work, don’t take public transport, go to work, don’t go to work," comedian Matt Lucas said in a short video which was watched almost four million times on Twitter. "If you can work from home, go to work.""And then we will or won’t, something or other."
