There are general principles you can follow to help prevent the spread of respiratory viruses, including:
Washing your hands more often - with soap and water for at least 20 seconds or use a hand sanitiser when you get home or into work, when you blow your nose, sneeze or cough, eat or handle food.
Avoid touching your eyes, nose, and mouth with unwashed hands
Avoid close contact with people who have symptoms
Cover your cough or sneeze with a tissue, then throw the tissue in a bin and wash your hands
Clean and disinfect frequently touched objects and surfaces in the home
