(CNN)UK Prime Minister Boris Johnson reimposed a lockdown in England on Monday as a more transmissible variant of Covid-19 fuels a surge in infections and hospitalizations in the country.
"It is clear that we need to do more to bring this new variant under control," Johnson said. "That means the government is once again instructing you to stay at home."
During his televised address to the nation, Johnson reimposed measures seen during the first lockdown last spring, including closures of secondary and primary schools to all except the children of key workers and vulnerable children. He added that this means it will not be "possible or fair for all exams to go ahead this summer as normal," and alternative arrangements are being put in place.
People will be allowed to leave their homes for limited reasons like shopping for essentials, exercise, and medical assistance. Johnson also said people could still leave home "to escape domestic abuse" -- an issue that arose earlier during the pandemic, as isolation and lockdown conditions exacerbated barriers to escape for victims of domestic violence.
International departures are now limited to those who have "a legally permitted reason," such as work.
Outdoor sports venues will have to close. But unlike spring's lockdown, nurseries will not be shuttered, elite sports can go ahead, and places of worship will remain open on the basis that attendees adhere to social distancing rules.
