<bot>: Yes, there are some things you can do to help prevent the spread of a cold or the flu. Make sure to wash your hands often with soap and water for at least 20 seconds. Avoid touching your face, especially when you're sick. Cover your coughs and sneezes with a tissue or your elbow. Stay home if you feel unwell and avoid close contact with others who may be sick.
