SARS-CoV-2通过空中传播的问题仍存在争议。这项快速审查的目的是评估与空调系统存在相关的新冠肺炎风险。原始研究(包括观察性和实验性研究)以英语撰写，没有时间限制，包括与暴发有关的SARS-CoV、MERS-CoV和SARS-CoV-2冠状病毒在空气中的传播。检索PubMed/MEDLINE、PubMed Central(PMC)、Google Scholar数据库和MedRxiv。为了扩大搜索范围，采取了滚雪球策略。14项研究报告了与空调系统有关的冠状病毒感染暴发。所有研究都是在远东地区进行的。在关于SARS的七项研究中，有六项通过病例的时空模式或空气流动动力学模型间接证明了供暖、通风和空调(HVAC)在疫情中的作用。在一份关于MERS的报告中，证明了暖通空调受到病毒颗粒的污染。在关于SARS-CoV-2的六项研究中，有四项是怀疑或通过计算机模拟支持病毒颗粒通过暖通空调的扩散。总而言之，有充分证据表明，在以前的亚洲疫情中，冠状病毒曾通过空气传播，各组织和国际机构发布的控制SARS-CoV-2在室内环境中传播的指南中已考虑到这一点。然而，暖通空调系统的技术差异阻碍了结果在世界范围内的推广。现有的为数不多的新冠肺炎调查没有提供足够的证据表明SARS-CoV-2病毒可以通过暖通空调系统传播。
The airborne transmission of SARS-CoV-2 is still debated. The aim of this rapid review is to evaluate the COVID-19 risk associated with the presence of air-conditioning systems. Original studies (both observational and experimental researches) written in English and with no limit on time, on the airborne transmission of SARS-CoV, MERS-CoV, and SARS-CoV-2 coronaviruses that were associated with outbreaks, were included. Searches were made on PubMed/MEDLINE, PubMed Central (PMC), Google Scholar databases, and medRxiv. A snowball strategy was adopted to extend the search. Fourteen studies reporting outbreaks of coronavirus infection associated with the air-conditioning systems were included. All studies were carried out in the Far East. In six out the seven studies on SARS, the role of Heating, Ventilation, and Air Conditioning (HVAC) in the outbreak was indirectly proven by the spatial and temporal pattern of cases, or by airflow-dynamics models. In one report on MERS, the contamination of HVAC by viral particles was demonstrated. In four out of the six studies on SARS-CoV-2, the diffusion of viral particles through HVAC was suspected or supported by computer simulation. In conclusion, there is sufficient evidence of the airborne transmission of coronaviruses in previous Asian outbreaks, and this has been taken into account in the guidelines released by organizations and international agencies for controlling the spread of SARS-CoV-2 in indoor environments. However, the technological differences in HVAC systems prevent the generalization of the results on a worldwide basis. The few COVID-19 investigations available do not provide sufficient evidence that the SARS-CoV-2 virus can be transmitted by HVAC systems.
