Governments around the world are encouraging people to stay at home to protect health services and save lives.
Among the new measures being brought in the UK, people can only leave their homes to buy food, medicine and to exercise.
They're allowed to travel, but only to and from work if they cannot do their jobs from home.
Staying at home to keep people safe can be a difficult concept to grasp, especially when you are feeling fit and healthy yourself.
BBC health reporter Laura Foster looks at the statistics which show just how much of a difference it can make when it comes to taking pressure off health services and saving lives.

Do as they say, not as they do! Officials advising the public on how to limit the spread of coronavirus keep touching their face - moments after telling people not to. President Trump said he hasn't touched his face "in weeks" - but photos show him resting his head on his hands during the coronavirus crisis. Dr. Ezekiel Emanuel said that it's important to avoid touching the "T-Zone," the space near the eyes, nose and mouth. Plus, Inside Edition's digital team fields questions from viewers. What probably started with a single sneeze is now a pandemic, so far infecting at least 120,000 people in more than 100 countries.
World leaders are warning the coronavirus crisis is going to get worse, but isn't unstoppable.
The measures to limit the spread vary from simply washing your hands - to complete isolation.
And it's not always your choice to decide how to protect yourself.
Governments have taken drastic action to help contain the disease.
China and Italy have locked down entire cities - hundreds of millions of people staying at home or off work.
Football matches and other sporting events are cancelled or played behind closed doors.
The US President has banned all transatlantic flights from Europe - except the UK - for 30 days.
And he's announced help for companies struggling to stay in business
But are travel bans enough?
