Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which has lasted for nearly a year, has made people deeply aware of the strong transmissibility and pathogenicity of SARS-CoV-2 since its outbreak in December 2019. By December 2020, SARS-CoV-2 had infected over 65 million people globally, resulting in more than 1 million deaths. At present, the exact animal origin of SARS-CoV-2 remains unclear and antiviral vaccines are now undergoing clinical trials. Although the social order of human life is gradually returning to normal, new confirmed cases continue to appear worldwide, and the majority of cases are sporadic due to environmental factors and lax self-protective consciousness. This article provides the latest understanding of the epidemiology and risk factors of nosocomial and community transmission of SARS-CoV-2, as well as strategies to diminish the risk of transmission. We believe that our review will help the public correctly understand and cope with SARS-CoV-2.
Core Tip: The coronavirus disease 2019 pandemic has not only placed a heavy burden on the health system but has also led to significant sociological, psychological, and economic adverse effects globally. A comprehensive understanding is needed of the risk factors of transmission of severe acute respiratory syndrome coronavirus 2 and strategies to diminish this risk. At the same time, people need to act in a socially responsible and cohesive manner, thus creating a common living space with a low risk of infection.
