a high temperature – this means you feel hot to touch on your chest or back (you do not need to measure your temperature)
a new, continuous cough – this means coughing a lot for more than an hour, or 3 or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual)

To protect others and yourself, do not go to crowded places.

How long to stay at home
if you have symptoms of coronavirus, you’ll need to stay at home for 7 days
if you live with someone who has symptoms, you’ll need to stay at home for 14 days from the day the first person in the home started having symptoms
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.
