Long Covid: Immune System's Lingering Battle
12 Aug
Summary
- Long Covid patients' immune systems may fight viral remnants.
- This prolonged battle causes ongoing inflammation.
- The body fails to fully eliminate the source of the issue.

The immune systems of individuals experiencing long Covid may be stuck in a prolonged fight against lingering remnants of the coronavirus. This ongoing battle appears to generate inflammation without effectively eliminating the virus's source.
Research from the University of California, San Francisco indicates an extensive immune response in long Covid patients. This suggests their immune systems remain hyperactive, battling residual viral material.
This persistent immune activation could explain the widespread and varied symptoms associated with long Covid. The failure to fully clear the virus may be a critical factor.
