Coronaviruses are generally thought to be spread most often by respiratory droplets that are spread through sneezing and coughing.

However, the virus has been found from stool for the first time from a patient who only presented with diarrhoea and no other symptoms. This has raised the possibility of feaco-oral transmission (the virus being transmitted through human stool). The best way to prevent any infection that can be transmitted through stool is regular handwashing particularly for breast or bottle feeding mothers.
