Meanings of infectious aerosols in inglés

Background: The interaction between the source of respiratory infectious aerosols and the receiver has not been investigated.

Air samples were regularly collected from the MBSL-3 Lab, but no evidence of Ebola virus infectious aerosols was detected.

First the subjects were injected with infected lung tissue taken from the dead and then sprayed in the eyes, nose, and mouth with infectious aerosols.

But, it adds: "There is currently no evidence of human infection with Sars-CoV-2 caused by infectious aerosols distributed through the ventilation system ducts of HVACs."
