On March 11, 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic. 

 Since then, the disease has claimed more than 6.14 million lives worldwide, and has affected daily life in countless ways. Some countries are now trying to return to normal, although there is still a risk of a new wave of epidemic viruses. Two years later, let's look at what the world has learned during the epidemic. 

 Infectious diseases are a problem of the whole society:

 One in every 1,300 people alive in 2019 has died from SARS-CoV infection, but when we look back at Wade 19 in the future, we see the direct impact on health. 

 Most will remember but experts warn that other routines of his life. The effects of stress on the health system and mental health are the effects that one it will be felt for a long time.  

Prolonged school closures have caused irreparable damage, especially to children from low-income families.  Overall, the economic damage and displacement caused by airborne disease has degraded the living standards of people around the world.

 Major changes in vaccine preparation procedures:

 Today, two years later, it is probably easier for us to forget how remarkable the development of Code 19 vaccines was. In a strict regulatory environment, the journey from the genomic sequencing of code 19 to the acquisition of permission was completed in just 326 days, thus breaking all previous records for vaccine development. 

 In addition, biomedical sciences have provided numerous vaccines against acute covid-19 with high efficacy and overall safety profile. Now the standard of competition has increased and there is a serious debate as to whether a vaccine will be prepared in 100 days against any future epidemic in emergency medical conditions.

 Structural change for equal distribution: 

 Despite the achievements of vaccine research and development, there are persistent inequalities in access to its benefits. Significant increases in global vaccine capacity for emergencies will help ensure rapid access to vaccines for large numbers of people in the future. 

 The location of vaccine production is also important in low-income regions. Are planning to increase their local capacity to reduce reliance on global agreements and long-term supply chains during the next infectious disease crisis.

 Confidence in an effective epidemic response:

 Prior to the outbreak, it was assumed that there would be a high demand for safe vaccines that provide a high level of protection against the often deadly and socially modifying epidemic. 

 This has certainly been seen in some countries during the current epidemic, but overall skepticism and hesitation against the vaccine has been rare. In this epidemic, the success of the public health system, as in other cases, depends on the public trust in the government and the shared social consensus.

 Agility and speed make everything unique:

 The epidemic has resurfaced every time, contrary to expectations. Our response to this has always been in the light of the new information available.   

Evidence agrees on changes in policy and practice on topics such as the benefits of wearing a mask, the likelihood of recurrence of infection, the risk of new strains, difficulty acquiring immunity over time against an epidemic, and the benefits of supplementation. Opinions need to be generated. 

 Countries, businesses, and other partners need to balance the benefits of incorporating new evidence into their response plans to address this confusion and frustration. Research shows that agility and strong communication enable some companies to deal with crises more effectively than others.

 Can such problems be faced again?

 In addition to the loss of precious human lives, the current and high incidence of the disease has cost the global economy an estimated  16 trillion. 

 "This is not the last epidemic," said an international research report the 5 dollar per capita investment could help the global community respond more effectively to future future epidemics through an ever-evolving response system, disease prevention, hospital preparation and research and development.

 Global leadership is needed for a sustainable future:

 Despite the initial low emissions at the onset of the epidemic, concerns about global warming have not abated and there is a near consensus that environmental catastrophe is possible without major changes.

 The world is now expected to have the same kind of leadership in the fight against climate change as the world has shown in the fight against epidemics. People do not understand how to change their lifestyles to save the planet, and the biggest challenge is to take the lead in global change.
