Evidence for Aerosol Transfer of SARS-CoV-2-Specific Humoral Immunity

Immunohorizons. 2023 May 1;7(5):307-309. doi: 10.4049/immunohorizons.2300027.


Infectious particles can be shared through aerosols and droplets formed as the result of normal respiration. Whether Abs within the nasal/oral fluids can similarly be shared between hosts has not been investigated. The circumstances of the SARS-CoV-2 pandemic facilitated a unique opportunity to fully examine this provocative idea. The data we show from human nasal swabs provides evidence for the aerosol transfer of Abs between immune and nonimmune hosts.
