Abstract:
SARS-CoV-2 Delta variant has the characteristics of stronger infectivity, higher viral load, and shorter incubation period, posing new challenges to the prevention and control of COVID-19 pandemic. SARS-CoV-2 Delta variant was first discovered in India, then quickly spread in many countries and has gradually become one of the main epidemic strains worldwide. Local epidemics caused by SARS-CoV-2 Delta variant also occurred in several provinces in China. This article summarizes the progress in research of etiological characteristics, transmission characteristics or possible mechanism and epidemiological characteristics of SARS-CoV-2 Delta variant, and the protective effects of vaccines and control measures against SARS-CoV-2 Delta variant in order to provide references for the effective prevention and control of COVID-19 epidemic caused by SARS-CoV-2 Delta variant.
