The virus enters your body via your eyes, nose and/or mouth, so it is important to avoid touching your face with unwashed hands.
Washing of hands with soap and water for at least 20 seconds, or cleaning hands thoroughly with alcohol-based solutions, gels or tissues is recommended in all settings. It is also recommended to stay one metre fifty or more away from people infected with COVID-19 who are showing symptoms, to reduce the risk of infection through respiratory droplets.
