Coughing or sneezing into your elbow catches the droplets and stops them getting onto your hands.

Like the flu, COVID-19 can be transmitted from person to person. The scientific evidence confirms that COVID-19 is spread by droplets. When an infected person coughs, sneezes or talks, they may generate droplets containing the virus. These droplets are too large to stay in the air for long, so they quickly settle on surrounding surfaces. If other people touch these surfaces they may get sick.
For most people facemasks are not recommended. Facemasks play an important role in clinical settings, such as hospitals. For people with symptoms of an acute respiratory infection, there may be benefit in wearing a facemask to reduce the spread of infection to other people.
