What should I do if I have symptoms of Coronavirus (COVID-19)? If you develop symptoms of Coronavirus (COVID-19) (high temperature above 37.8 °C and/or new and continuous cough), seek clinical advice using the NHS 111 online coronavirus service or call NHS111 if you don’t have internet access. In an emergency, call 999 if you are seriously ill. Do not visit the GP, pharmacy, urgent care centre or a hospital. Do this as soon as you get symptoms. The same guidance applies to the general population and those at increased risk of severe illness from COVID-19. If you develop symptoms of COVID-19, self-isolate at home for 7 days. You can find the full guidance at stay at home.
