AI Article Synopsis
- SARS-CoV-2 mainly spreads through the air, though it can also be transmitted via direct contact and contaminated surfaces.
- Variants-of-concern (like Delta and Omicron) are generally more contagious than the original strain of the virus.
- Early VOCs have better stability in the air and on surfaces compared to the initial WA1 strain, but this increased stability doesn't account for their higher transmissibility.
Article Abstract
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.
