Science.org Blog Weighs Emerging Evidence on Long Covid's Causes

A Science.org blog post examines the current state of research into what drives Long Covid, the persistent multi-system illness that follows acute SARS-CoV-2 infection in a meaningful fraction of patients. The piece falls outside the usual technology beat, focusing instead on biomedical mechanisms under active investigation by virologists and immunologists.

The full article body was not available for summarization beyond the headline, so specifics on which causal hypotheses the author favors — viral persistence, autoimmunity, microclotting, latent virus reactivation, or vagal/neurological dysfunction — cannot be reported here. Readers seeking the underlying argument should consult the source directly at science.org.
