Why does Tedros Adhanom Ghebreyesus say that COVID-19 is a health crisis once in a century?

Because this time COVID-19's influence involves the whole world, this epidemic is rare in a hundred years, and this epidemic will have an impact on human beings for decades. More importantly, the hidden things that COVID-19 brought to the human body have not been discovered.

Tan Desai is the Director-General of WHO. When he convened an emergency committee before, he said that COVID-19 is a once-in-a-century health crisis, and more importantly, its impact will last for decades, not just the last two years. Serum research shows that most people in the world are easily infected with the virus. Even those areas that have experienced severe epidemics are still facing the crisis of repeated infections. Some countries that were less affected at first have not escaped the clutches of the epidemic, and the number of confirmed patients and the proportion of deaths have started to rise steadily.

He also said that although scientists are now cooperating to develop vaccines, and the research and development of vaccines is also born at a record speed, we should know that learning and viruses coexist, and we should use existing tools to fight the epidemic before the emergence of vaccines, such as making full use of existing treatment methods in medical institutions and medical materials.

Especially this time, COVID-19's influence will last for decades, because COVID-19 patients may have physical problems in the next few decades, because COVID-19 will attack patients' liver, kidneys and nervous system. Because everyone's constitution is different, the symptoms of COVID-19's disease are also different. Some symptoms only appear during the illness and have no effect after being cured, but some are permanent injuries that require extreme vigilance of human beings.

Secondly, the economic impact of the epidemic on human beings may affect the next few years, because the epidemic will not end until at least 202 1 year, and if it is more serious, it may not be until 2022, that is to say, it will take at least three or four years for the economic situation to recover, and by 20 19, it will pay a huge price to stimulate the economy again during this period. This is not only a health crisis, but also an economic crisis.
