Long Covid - ChrisGreene - 01-10-2022

I am not competent to evaluate this. I do not know the reputation of the Norwegian Institute of Public Health.

Given the disclaimer, this covers some of the first data I've seen covering long covid.

They look at people that got COVID (separately in two different waves). Then they compare long covid symptoms between people that didn't get covid and people that did.

Thanks! Interesting.

Somewhat disappointingly, the number of those with COVID in their study was < 1000. Enough for statistics.

You can see absolute risk and relative risk for various symptoms at 1-6 months after COIVD on page 10, 11-12 months after COVID on page 9.

Table 4 compares the longer-term symptoms (sum of 1-6 months & 11-12 months) for those with "almost no illness" versus those with moderate/severe illness. This may be of interest for Omicron. There was about twice the risk for those with moderate/severe COVID to have any particular symptom, but those with mild COVID with symptoms still had increased risk of longer-term symptoms (6.9% had shortness of breath, 10.2% had fatigue, 16% had altered smell or taste).

From the clustering of symptoms, they postulate two (unknown) factors behind the increased risk for various long-lasting symptoms. That's in table 5 on page 12. One factor would increase your risk for brain fog, memory issues, heart palpitations, fatigue, and such (altered smell/taste is associated with this factor). The other factor would increase your risk of cough, reduced lung function, and chest pain.
