Colloquially known as coronavirus, the Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2), that causes CoronaVirus Disease 2019 (COVID-19), has become a matter of grave concern for every country around the world. The rapid growth of the pandemic has wreaked havoc and prompted the need for immediate reactions to curb the effects. To manage the problems, many research in a variety of area of science have started studying the issue. Artificial Intelligence is among the area of science that has found great applications in tackling the problem in many aspects. Here, we perform an overview on the applications of AI in a variety of fields including diagnosis of the disease via different types of tests and symptoms, monitoring patients, identifying severity of a patient, processing covid-19 related imaging tests, epidemiology, pharmaceutical studies, etc. The aim of this paper is to perform a comprehensive survey on the applications of AI in battling against the difficulties the outbreak has caused. Thus we cover every way that AI approaches have been employed and to cover all the research until the writing of this paper. We try organize the works in a way that overall picture is comprehensible. Such a picture, although full of details, is very helpful in understand where AI sits in current pandemonium. We also tried to conclude the paper with ideas on how the problems can be tackled in a better way and provide some suggestions for future works.

严重急性呼吸系统综合症冠状病毒 2 (SARS-CoV-2) 俗称冠状病毒，它会导致 2019 年冠状病毒病 (COVID-19)，已成为世界各国严重关注的问题。疫情的迅速蔓延造成了严重破坏，需要立即采取应对措施来遏制其影响。为了解决这些问题，各个科学领域的许多研究已经开始研究这个问题。人工智能是在解决许多方面的问题方面发现了巨大应用的科学领域之一。在这里，我们概述了人工智能在各个领域的应用，包括通过不同类型的测试和症状诊断疾病、监测患者、识别患者的严重程度、处理 covid-19 相关成像测试、流行病学、药物研究本文的目的是对人工智能在应对疫情造成的困难中的应用进行全面的调查。因此，我们涵盖了人工智能方法的每一种应用方式，并涵盖了直到撰写本文为止的所有研究。我们尝试以一种易于理解的整体方式来组织作品。这样的图景虽然充满了细节，但对于理解人工智能在当前混乱局面中的地位非常有帮助。我们还试图总结本文，提出如何更好地解决问题的想法，并为今后的工作提供一些建议。
