Human Coronaviruses cause infections of the nose, throat and lungs. They are most commonly spread from an infected person through: 

• respiratory droplets generated when you cough or sneeze 
  
• close, prolonged personal contact, such as touching or shaking hands 
  
• touching something with the virus on it, then touching your mouth, nose or eyes before washing your hands 

We encourage all travellers to engage in preventative measures as outlined: 

• wash your hands often with soap and water for at least 20 seconds 
  
• avoid touching your eyes, nose or mouth with unwashed hands 
  
• stay home if you are sick 

When coughing or sneezing: 

• cover your mouth and nose with your arm or tissues to reduce the spread of germs 
  
• immediately dispose of any tissues you have used into the garbage as soon as possible and wash your hands afterwards
