COVID-19 spreads by air and can be transferred via airborne droplets or ventilation systems even though you may not have had direct contact with the infected person. To lower your chance of airborne transmission, follow these five steps:
- Increase ventilation in indoor spaces
- Use natural ventilation
- Avoid air recirculation
- Make sure you are not in another person's direct air flow
- Keep the number of people you meet with to a minimum
