Trisha Greenhalgh and colleagues explore why inaccurate narratives about the mode of transmission of SARS-CoV-2 emerged early in the pandemic and shaped a flawed policy response, with tragic consequences
Key messages
- A flawed narrative that SARS-CoV-2 was transmitted by droplets rather than being airborne became entrenched early in the pandemic
- Measures aimed at an assumed droplet pathogen (handwashing, surface cleansing, physical distancing) were over-emphasised
- Measures to reduce airborne transmission (improving indoor air quality, reducing indoor crowding and time spent indoors, and high-grade respiratory protection) were under-emphasised
- UK policy makers seemed to favour narratives from a narrow group of scientific advisers
- Consequences included care home deaths, mission critical delays in public masking, and avoidable infections of healthcare workers
