  How does COVID-19 spread?

  COVID-19 is caused by the SARS-CoV-2 virus. Current evidence suggests that the virus spreads mainly among people who are in close contact with each other, for example at a conversational distance. The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe. Another person can then contract the virus when infectious particles that pass through the air are inhaled at a short-range (this is often called short-range aerosol or short-range airborne transmission) or if infectious particles come into direct contact with the eyes, nose, or mouth (droplet transmission).

  How to protect yourself from COVID-19?

  How to protect yourself from COVID-19?

  If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as social distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue.
  ① Maintain at least a 1-metre distance between yourself and others to reduce your risk of infection when they cough, sneeze or speak. Maintain an even greater distance between yourself and others when indoors. The further away, the better.
  ② Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal are essential to make masks as effective as possible.
  Here are the basics of how to wear a mask:
  ① Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.
  ② Make sure it covers both your nose, mouth and chin.
  ③ When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.
  ④ Don’t use masks with valves
