Damaged immune system

Those reporting Long Covid symptoms showed measurable abnormalities in their immune system that can persist at least 8 months.

Patients with Long Covid had evidence of ongoing inflammation including highly activated immune cells, lack of inactivated T and B cells, and elevated presence of cytokines that are signatures of ongoing active immune response. This provides further evidence of physical damage from Long Covid.
