Extra financial measures are set to be announced by the government with UK firms at risk of going out of business thanks to the coronavirus restrictions.
Covid-19 has already claimed 55 people in Britain, prompting Prime Minister Boris Johnson to urge citizens to maintain social distance as well as steer clear of pubs and restaurants, and work from home as much as possible.
Those most vulnerable to the potentially deadly virus will also be asked to self isolate for three months in the coming days.
Cases in Britain are feared to be as high as 50,000 despite only 1,500 having actually been tested.
Chancellor Rishi Sunak will set out a new package of support for businesses hit by the outbreak less than a week after announcing £30 billion of emergency funding in the Budget, the Mirror understands.
Mr Sunak is also expected to join the PM at the daily Downing Street news conference later today.
Among the new measures is likely to be aid for the struggling airlines while pubs, theatres and music venues have all voiced concerns about how they will fare under the new strict guidance.
Despite not forcing closures, Mr Johnson instead advised people to avoid going to public venues, leaving many with uncertain futures.
The National Theatre, London Palladium and Royal Opera House have all confirmed they are among many venues across Britain to close until further notice.
The PM has admitted the country's economy is facing a "severe blow" due to the epidemic.
New measures also include all "unnecessary" visits to care homes to stop.
People have been told to only use the NHS when only completely necessary while those who are vulnerable or have serious health problems should self-isolate for 12 weeks from next weekend.
These include over 70s, those normally advised to take the flu vaccine and pregnant women.
If one person in a household has a persistent cough or fever, everyone there should self-quarantine for two weeks, and should avoid leaving home even for food and essentials.
Schools, meanwhile, must remain closed.
Emergency legislation is set to be announced on Thursday while the Budget will get "nodded through" rather than facing calls for a vote.
Labour leader Jeremy Corbyn demanded support for the self-employed and those who cannot get statutory sick pay when meeting Mr Johnson on Monday night.
Despite being 70, the leader of the opposition said he would not self isolate and condemned the government's communication with the public as "worse than inadequate" while disagreeing with 'rationale' in some decision-making.
Yesterday the total number of people tested in the UK rose by 171 to 1,543 though most who have died have been over 60 and with underlying health problems.
The PM warned Britain is about to hit the "fast growth part" of the epidemic as the peak nears.
