Evidence supporting Airborne transmission

Info extracted from this document filled by @JenniferKShea, @jmcrookston and @jljcolorado.

In lab setting, aerosolized pathogen remains stable and/or viable (infectious) in the air after significant time has passed

Genetic material of pathogen detected in aerosol samples,  on air grates, in air vents and/or on low-/no- touch surfaces

Viable pathogen isolated from aerosol samples in laboratory settings (Cough/breath)

Viable pathogen isolated from air samples in non laboratory settings

MEASLES

INFLUENZA

CHICKENPOX

TUBERCULOSIS

SARS & MERS

SARS:
2004 · Xiao

MERS:
2016 · Kim

Outbreak investigations showing high likelihood of transmission over “long distances” (ie > 2m)

Nosocomial outbreaks and/or transmission events despite droplet/contact precautions

Animal models showing isolation of pathogen from aerosol samples and/or transmission through the air

Human challenge trials (unethical with COVID) OR Human to animal transmission studies
