Progress of study on biology, epidemiology and prevention strategies for SARS-CoV-2 lambda variant

The emergence of SARS-COV-2 caused the global pandemic crisis.As the pandemic evolves, the mutation of novel coronavirus genome continues, resulting in several novel coronavirus variants. For example, Alpha (B.1.1.7), Beta (B.1.351), Gamma (p.1), Delta (B.1.617.2) and Lambda (C.37) variants may cause changes in biological characteristics of the virus, such as pathogenicity and infectivity, which may lead immune escape from vaccine protection and antibodies, even bring greater harm to epidemic prevention and control and also disease treatment. In this paper, the pandemic characteristics and relevant prevention and control measures of lambda variant are reviewed.
