UK scientists have created an online calculator that shows how likely you are to die if you contract the new coronavirus disease Covid-19.
Experts from University College London say there are more than eight million people who are 'high risk' so should stay indoors until the lockdown is completely lifted.
They say if people at risk from Covid-19 leave the home or ignore lockdown rules then the number of deaths in the UK could go over 73,000.
And they say if the government removes restrictions too fast, the virus could spread out of control and kill 400,000 people, Sun Online reports.
Researchers warn the risk of death among people with underlying health conditions - such as heart disease or diabetes - is five times higher than those without and the over 70s are also at risk.
They have estimated there are 8.4 million people in the UK who need to avoid going outdoors to curb an increase in deaths.
The team created the Covid-risk calculator that allows individuals to see if they are deemed vulnerable and take any necessary steps to safeguard themselves.
It uses an individual's age, sex and underlying health conditions to assess their effect on coronavirus mortality under different scenarios..
Dr Amitava Banerjee, lead researcher, said the calculator is an early prototype and provides one-year mortality risks for common conditions by age and sex.
He added: “Using data modelling on a number of different scenarios, our findings show the mortality risk for these vulnerable groups increases significantly, and could lead to thousands of avoidable deaths.
“Our calculator is the first to give doctors, health experts and the public a personalised risk from Covid.
“In the current emergency there is an urgent need to develop better understanding of who is at risk based on reliable health data.”
Professor Sarah Harper, from Oxford University, said the calculator highlights 'the importance of identifying underlying health conditions'.
