Uncovering the Role of "Zombie" Viral Fragments in Severe COVID-19 Cases

A new AI study suggests that "zombie" viral fragments of SARS-CoV-2, unique to the COVID-19-causing virus and not found in its harmless cold-causing cousin, may be responsible for the variable severity of COVID-19. These fragments resemble human immune system molecules and can trick the body into overreacting, leading to severe inflammation. Individual differences in enzyme efficiency also play a role in determining the severity of the illness. This research offers insights into why COVID-19 affects people differently and opens possibilities for future treatments targeting these fragments.
