The Prime Minister told MPs that the rules around statutory sick pay would be changed to ensure nobody was "penalised" for self-isolating.
Speaking in the Commons chamber Boris Johnson said the rules would be changed temporarily to allow statutory sick pay to be paid from the first day for those who have to self-isolate.
Johnson said: "The Health Secretary will bring forward, as part of our emergency coronavirus legislation, measures to allow the payment of statutory sick pay from the very first day you are sick instead of four days under the current rules, and I think that’s the right way forward.
“Nobody should be penalised for doing the right thing.”
The Prime Minister had faced calls from Labour leader Jeremy Corbyn and the SNP's Westminster leader Ian Blackford to ensure workers and those on benefits were protected during the crisis.
Corbyn said the change did not go far enough because a £118-a-week income threshold is still in place that blocks sick pay to some 2 million low-paid workers.
Johnson said those on low-pay could claim Universal Credit instead, however Corbyn said they would face a "terrible choice between health and hardship" due to the five week waiting period for the benefit.
Those an sick pay are entitled to one payment of £94.25 a week.
The Scottish Government health secretary Jeane Freeman announced on Wednesday morning that two new cases of the virus had been confirmed in Scotland.
It brings the total number of confirmed Covid-19 cases in Scotland to three; whilst around 1000 have been tested.
The locations of the new cases have not been revealed, although it was previously announced the first patient was in Tayside.
She explained health authorities would move into the "delay" phase of their response when they start to see "community" transmission of the disease.
The government's worst-case scenario for the virus suggests 80% of Scotland's population could be infected, with around a fifth of those falling ill.
