I am not sure about that. If you mean is tracking the cases, it is not necessary needes blockchain for that purpose. Blockchain goal cannot be tapped on ths one whatever we think any of help it can give. But it can help those people by using blockchain as a way to spread the help such as donation and using it as fast transaction for funds that will be used for helping affected community or hospitals. Aside from it, I cannot see elsewhere we can utilize it for fighting the corona virus. What we need here is a cure or any vaccine that can kill it totally.
