Episode notes
Airborne Spread Made COVID Harder To Control
- SARS and MERS showed coronaviruses can kill many, but COVID proved high infectiousness with lower fatality.
- Airborne aerosol transmission made COVID far harder to control than earlier coronaviruses.
Stadium Measles Case Shows Long-Range Aerosols
- Osterholm recounted a Minneapolis measles outbreak where air currents infected people 490 feet away.
- The case illustrated how aerosols can travel long distances and infect distant spectators.
Make Masks People Will Wear
- Invest in comfortable, highly effective respiratory protection that people will actually wear for long periods.
- Prioritize reusable, sealed respirators and better indoor air quality to reduce aerosol transmission.
