The latest government guidance is that you, and everyone living in your household, should stay at home - if you have either:
- high temperature - you feel hot to touch on your chest or back
- new continuous cough - this means you've started coughing repeatedly
If you have the symptoms of coronavirus, you must stay at home for 14 days starting from the day you have become ill.
If you live with others and you or one of them have symptoms of coronavirus, then all household members must stay at home and not leave the house for 14 days, irrespective if they have the symptoms. The 14-day period starts from the day when the first person in the house becomes ill.
If you live with someone who is 70 or over, has a long-term condition, is pregnant or has a weakened immune system, try to find somewhere else for them to stay for 14 days.
If you have to stay at home together, try to keep away from each other as much as possible.
