SARS-CoV-2 is transmitted principally via air; contact and fomite transmission may also occur. Variants-of-concern (VOCs) are more transmissible than ancestral SARS-CoV-2. We find that early VOCs show greater aerosol and surface stability than the early WA1 strain, but Delta and Omicron do not. Stability changes do not explain increased transmissibility.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）主要通过空气传播；接触传播和污染物传播也可能发生。值得关注的变异株（VOCs）比原始的SARS-CoV-2更具传播性。我们发现，早期的VOCs在气溶胶和表面上比早期的WA1毒株表现出更高的稳定性，但德尔塔和奥密克戎变异株并非如此。稳定性变化并不能解释传播性的增加。
