Abstract

Abstract

COVID-19 is still in the state of global pandemic currently. The Omicron variant is still the dominant strain worldwide, and many new subvariants have evolved and emerged continually during the pandemic. XBB is a recombinant of Omicron variants BA.2.10.1 and BA.2.75 sublineages, which was first identified in India in August 2022. Since then, it has rapidly spread to become the main epidemic variant in Singapore, Malaysia, as well as some European and American countries, and evolved some sublineages such as XBB.1, XBB.1.5, etc. XBB has a significantly increased immune escape ability compared with other circulating Omicron subvariants. But there is no evidence that the severity of XBB infection differs from other Omicron subvariants. It is recommended to strengthen the monitoring of virus mutation, carry out vaccination with booster doses in key populations, accelerate the research and development of vaccines and drugs, carry out multi-source monitoring to assess the risk dynamically, and timely take corresponding scientific prevention and control measures to reduce the threat of XBB strain.
