- While social distancing has slowed transmission of COVID-19, understanding how airborne droplets travel is important for informing public health.
- When we cough or sneeze we expel micro-droplets which follow the principles of fluid mechanics.
- Research has shown that these droplets can travel as far as 7m (20ft).
COVID-19 has sharply brought into focus the impact of respiratory infectious diseases on humanity. It has also shown that the greatest defence against health crises is government policy that is strongly rooted in science.
