Lessons learned from corona 1. The powerful countries of the world have spent crores to build nuclear bombs as well as systems to counter those, they have spent crores for space science also but no country has built a system that can resist an epidemic. Very little research has been done in microbiology although a lot of research in microbiology should have been done. However, no country has shown much of interest so research in microbiology did not get more scope. How dangerous these minute organisms can be the humans have realised now. Had there been a little more research on viruses, if we had a little more knowledge about viruses then we could have easily resisted this corona. Our knowledge about viruses is very limited.
