Lessons must be learned from the mistakes of the Covid pandemic. some countries facing persistently high infections may have used the wrong strategy, leaving them facing persistently high infections. This book will analyse what have been the main mistake since the Covid pandemic. This book also suggest a system to solve pandemic problem so that it can be used in future pandemic.

Prevention is better than cure. Instead of creating new medical treatment or vaccine for viruses or mutant viruses, it is better to create a system to prevent the spread of pandemic viruses. As we have seen, China and South Korea managed to solve the covid-19 surge in their countries without using vaccines in 2020. Therefore, the epidemic prevention system must be able to detect any wrong guidelines faster to prevent the use of the wrong guidelines from causing widespread spread of the virus.

For pandemics, waiting for research evidence to implement non-medical prevention strategies is a big mistake, because the prime time to reduce the spread of the virus has been missed. It takes time to generate research evidence, and follow-up peer review also takes time, so the process of peer review research evidence allows the virus to spread widely, and some mutations may occur, making virus prevention more difficult to deal with.
