The latest research progress of the Corona Virus Disease 2019 mutant strain "Omicron"

Coronavirus disease 2019 (COVID-19) that broke out at the end of December 2019 has been raging for 3 years, bringing unpredictable harm to the physical and mental health of all mankind and global economic development. The new type of coronavirus pneumonia is a new type of respiratory infectious disease with a high incidence and fatality rate caused by SARS-CoV-2. Up to now, hundreds of millions of people have been infected with new coronary pneumonia worldwide, and millions of people have died. Due to the specificity of the new coronavirus itself and its high mutation rate, a series of different new coronavirus variants have appeared, which has caused the new crown pneumonia epidemic to repeat. Recently, the World Health Organization (WHO) announced a new variant "omicron" (omicron, B.1.1.529), and declared that the mutant strain may be highly infectious, antibody tolerant and highly resistant to vaccines. This article briefly reviews the latest research progress of the "omicron" variants.
