We are seeing, and will continue to see, economic stimulus both from central banks (monetary policy) and government (fiscal). A criticism I've seen is these will not cure the coronavirus. Of course they won't, what they are intended to do is ease the economic cost. The scientists working on vaccines, cure, and the other health-related concerns are the most important folks right now, but the folks applying the (economic) band aids are doing what they can. Economic support should help stabilise markets (its about dissipating fear right now).
