Symptom Duration and Risk Factors for Delayed Return to Usual Health Among Outpatients with COVID-19
https://pubmed.ncbi.nlm.nih.gov/32730...
US CDC
Random sample of 292 adults who had tested positive
35% of 274 symptomatic respondents, not returned to usual health 14 – 16 days after testing
18 – 34 year olds
N = 85, 26%. (74% returned to normal)
35-49 years
N = 96, 32% (68% returned to normal)
50 and older
N = 89, 47% (53% returned to normal)
Post–intensive care syndrome
6 – 12 months, cognitive, mental health, physical function
Persistent Symptoms in Patients After Acute COVID-19 (JAMA, July 2020, Rome)
https://jamanetwork.com/journals/jama...
143 patients discharged from the hospital
18 patients (12.6%) were completely free of any COVID-19–related symptoms after a mean of 60 days
Therefore 87.4 not returned to full normal
Manifestations
None of the patients had fever or any signs or symptoms of acute illness
Worsened quality of life, 44.1%
Pathogenesis
Direct tissue invasion by the virus
The virus cleares from most of the body, but lingers in some small pockets
If there's long-term diarrhoea then you find the virus in the gut, if there's loss of smell it is in the nerves - so that could be what's causing the problem (Tim Spector)
