During previous outbreaks due to other coronavirus (Middle-East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS), human-to-human transmission occurred through droplets, contact and fomites, suggesting that the transmission mode of the COVID-19 can be similar. The basic principles to reduce the general risk of transmission of acute respiratory infections include the following:

• Avoiding close contact with people suffering from acute respiratory infections.
• Frequent hand-washing, especially after direct contact with ill people or their environment. 

People with symptoms of acute respiratory infection should practice cough etiquette (maintain distance, cover coughs and sneezes with disposable tissues or clothing, and wash hands). Clean your hands by washing them with soap and water for at least 20 seconds or using an alcohol-based hand sanitizer that contains 60%–95% alcohol immediately after coughing, sneezing, or blowing your nose. Soap and water should be used if hands are visibly dirty.

Do not travel while sick.
