When we know the full extent of the virus? It's an easy question to ask, but an incredibly hard one to answer. For example, they've been finding that the virus can trigger strokes in otherwise healthy individuals. That's individuals that either exhibit no symptoms or minor symptoms. So while they may otherwise be asymptomatic, we can't know unless we do a full extensive test to see if they're also suffering from unseen clotting issues.
