This shows the number of assessments carried out by NHS helplines (111 and 999 phone calls and 111 online) for people who are assessed as having symptoms of Covid-19. Note that the figures show the number of assessments - not the number of people who contact the NHS.
This is an important early warning indicator. Health experts have shown a strong association between changes in these figures and changes in the number of deaths from Covid-19 that happen 16 days later.
