Whatr was Jesus's opion on Viruses?

HE IS NOT THRILLED with them but we are ruining the world. How sad.

He wasn't fond of them.

Luke 21:10,11 he mentioned signs of the last days of the system of things..."Then he said to them: “Nation will rise against nation, and kingdom against kingdom.  There will be great earthquakes, and in one place after another food shortages and pestilences.."
There has been a number of pestilences through out history.
So the prophesy is getting fulfilled. 
When Jesus was on earth, he cured all sorts of diseases and raised some people from the dead. In the future He and Jehovah God will do the same on a global scale. (Revelation 21:3,4; John 5:28,29)
