SARS-CoV-2 RNA survives in the human brain and multiple organs for up to 230 days after the first symptoms appear.

Covid-19 was long considered a respiratory infection that the body clears after a few weeks of illness. Autopsies now reveal that the virus actually migrates throughout the entire body and parks itself in tissues for over seven months. These viral remnants were found in patients who only had mild symptoms and never went to the hospital. The long-term presence of this genetic material suggests the body is never truly finished with the virus even after a negative test. This provides a concrete biological explanation for why some people suffer from brain fog and fatigue for years.
