  The COVID-19 pandemic caused by the SARS-CoV-2 virus has spread rapidly
worldwide, leading to a global outbreak. Most governments, enterprises, and
scientific research institutions are participating in the COVID-19 struggle to
curb the spread of the pandemic. As a powerful tool against COVID-19,
artificial intelligence (AI) technologies are widely used in combating this
pandemic. In this survey, we investigate the main scope and contributions of AI
in combating COVID-19 from the aspects of disease detection and diagnosis,
virology and pathogenesis, drug and vaccine development, and epidemic and
transmission prediction. In addition, we summarize the available data and
resources that can be used for AI-based COVID-19 research. Finally, the main
challenges and potential directions of AI in fighting against COVID-19 are
discussed. Currently, AI mainly focuses on medical image inspection, genomics,
drug development, and transmission prediction, and thus AI still has great
potential in this field. This survey presents medical and AI researchers with a
comprehensive view of the existing and potential applications of AI technology
in combating COVID-19 with the goal of inspiring researchers to continue to
maximize the advantages of AI and big data to fight COVID-19.
