I agree, there is nothing God can do, God gave humanity something precious called FREE WILL. What is happening around the world is not God's fault, it's human greed, ignorance and negligence. I mean sure people can be upset at God and ask how can a loving God allow this to happen - Well you cannot have free will and control at the same time, otherwise we would have absolutely no control of what we do. God did not create the illegal wet markets where wild animals are snatched from their wild habitat and put into cages together crammed with other animals and then sold to humans for human consumption. Nothing God can do now, whatever disasters and mistakes humans make, they can fix.
The Spanish Flu killed millions before it eventually disappeared. This virus is likely to make a comeback in WAVES before disappearing - for that to happen you need a vaccine and at least 50-60% infected - I would not expect the virus to DISAPPEAR before at least 3 years - since it takes 12 to 18 months for a vaccine, and then you need production phase and supply, administering etc which could take a lot of time. It's very likely covid19 could become a seasonal strain like Influenza. Meanwhile the number of cases and deaths will likely slow down in a matter of months, which will be encouraging news, things will eventually become stable and under control - BUT the virus will never completely disappear, people will have to continue applying hygiene and changing their way of life for a while.
