How the Virus Spreads

Visualization of the coronavirus causing COVID-19

El País published an article with very nice visualizations of how the coronavirus spreads via aerosols. It’s a light and informative read. Main takeaways:

  • The main risk is spending prolonged time periods with an infected person in an unventilated rooms
  • (Ordinary) masks only help little in this scenario once the air is saturated with aerosols. Good ventilation and shortening the time spend together is most important.
  • Masks help during shorter encounters and if distance cannot be maintained.
  • Speaking (and even worse: singing) sheds much more particles than breathing in silence. Masks are more important in these scenarios
