Omicron variant was first found in Botswana, southern Africa, on November 9, 2021. The variant has many mutations and spreads quickly. It also has immune escape to existing COVID-19 vaccines, and the infection rate and repeated infection rate have increased worldwide. For such variant, at this stage, foreign countries mainly adopt three strategies to prevent and control the epidemic. First, big data is used to track the potential infection of the epidemic, trace the spread of the epidemic, screen close contacts, and control the scope of infection. The second is to maximum the coverage rate of vaccination, especially the coverage rate of the third injection, so as to reduce the infection level of Omicron variant. At last, they are developing a general coronavirus vaccine to prevent infection caused by SARS-CoV-2 variants, including the Omicron variant, so as to fundamentally eliminate the potential threat of variants to human beings. In this paper, three major epidemic prevention strategies of Omicron variant abroad were summarized in detail. [ABSTRACT FROM AUTHOR]
