To prevent the spread of COVID-19:

Clean your hands often. Use soap and water, or an alcohol-based hand rub.

Maintain a safe distance from anyone who is coughing or sneezing.

Wear a mask when physical distancing is not possible.

Don’t touch your eyes, nose or mouth.

Cover your nose and mouth with your bent elbow or a tissue when you cough or sneeze.

Stay home if you feel unwell.

If you have a fever, cough and difficulty breathing, seek medical attention.
