Covid-19 disease stages defined
NICE has defined three stages of Covid-19:
- Acute Covid-19 infection: Signs and symptoms of Covid-19 for up to four weeks
- Ongoing symptomatic Covid-19: Signs and symptoms of Covid-19 present from four weeks and up to 12 weeks
- Post-Covid-19 syndrome: Signs and symptoms that develop during or after an infection consistent with Covid-19, present for more than 12 weeks and are not attributable to alternative diagnoses.
