I honestly don't think a cure will prevent more calamities in the world. The most important thing is to address the underlying problem so that more similar disasters doesn't occur again anywhere in the world.
It will be fairly difficult and prohibitively expensive to bring Western hygiene standards to the massive populations in the underdeveloped world. 200,000 people are born every day, mostly to these impoverished countries.
There will always be viruses, but that will not be the downfall of humanity. Starvation will be. :/
You think hygiene and washing of hands will stop the earth from getting destroyed?
I totally believe rebellion and refusal to obey the CREATOR will lead our planet to its ruin. Sin actually destroys the body/societies and not really hygiene. I hardly get sick since I started obeying GOD Words. But I occasionally got sick while I was in rebellion with HIM despite living a "healthy lifestyle".
Isaiah 24:4-5:
"The earth dries up and withers; the whole world grows weak, both earth and sky decay. The people have defiled the earth by breaking God's laws and by violating the covenant he made to last for ever."
