Several factors keep virus particles suspended so they travel considerable distances, including the force and volume of exhalation, as well as the local humidity, temperature and airflow. With the pandemic at a critical stage we need urgent research to understand airborne transmission better. At the same time, international guidance must emphasise the risk of airborne transmission of Covid-19 and publicise preventive measures. But it is crucial that we take on board how our breathing, talking, singing and shouting is a significant route for spreading the virus. Recognising the importance of airborne transmission may prove a crucial breakthrough.
