Everyone should follow the latest NHS advice about coronavirus.

Doctors of the World have translated the latest NHS advice into 36 languages, visit the Doctors of the World website for more information and to access this information in another language.

The symptoms of coronavirus are:

  • 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)
  • A loss of smell or taste (also called anosmia)

If you have symptoms of coronavirus, you’ll need to self-isolate for 10 days.

To protect others, do not go to places like a GP surgery, pharmacy or hospital. Stay at home.

If you need help, use the 111 online coronavirus service to find out what to do. Only call 111 if you cannot get help online.
