Boris Johnson is launching a drive to equip the NHS with more ventilators, as No 10 indicated it could soon step up measures to tackle the coronavirus.
These include "shielding" elderly and vulnerable people - where they are kept apart from the wider population - and asking entire families to self-isolate.
The government has faced pressure to do more to tackle the epidemic after the UK death toll rose to 21 on Saturday.
Downing Street said it would continue to be guided by its medical experts.
