World Health Organization Director-General Tedros Adhanom Ghebreyesus in his New Year's message for 2022 is optimistic about mankind's victory over the new crown epidemic in 2022: mankind is expected to end the new crown epidemic in 2022. Although it has been two years, the total number of new coronary pneumonia (COVID-19) cases worldwide has now reached 287 million, and nearly 5.5 million patients have lost their lives. As we enter 2022, the novel coronavirus (SARS-CoV-2) is still a part of people's daily lives, and Director-General Tedros believes that as long as countries work together, the spread of the virus can be curbed.
