Questions & Answers

Should I wear a mask to protect myself?

Currently, there is not enough evidence for or against the use of masks (medical or other) in healthy individuals in the wider community.

Only wear a mask if you are ill with COVID-19 symptoms (especially coughing) or looking after someone who may have COVID-19. Disposable face mask can only be used once. If you are not ill or looking after someone who is ill then you are wasting a mask. There is a world-wide shortage of masks, so we urge people to use masks wisely.
The inappropriate use of masks may increase the risk of infection.

How to put on, use, take off and dispose of a mask?

  1. Remember, a mask should only be used by health workers, care takers, and individuals with respiratory symptoms, such as fever and cough.
  2. Before touching the mask, clean hands with an alcohol-based hand rub or soap and water
  3. Take the mask and inspect it for tears or holes.
  4. Orient which side is the top side (where the metal strip is).
  5. Ensure the proper side of the mask faces outwards (the coloured side).
  6. Place the mask to your face. Pinch the metal strip or stiff edge of the mask so it moulds to the shape of your nose.
  7. Pull down the mask’s bottom so it covers your mouth and your chin.
  8. After use, take off the mask; remove the elastic loops from behind the ears while keeping the mask away from your face and clothes, to avoid touching potentially contaminated surfaces of the mask.
  9. Discard the mask in a closed bin immediately after use.
  10. Perform hand hygiene after touching or discarding the mask – Use alcohol-based hand rub or, if visibly soiled, wash your hands with soap and water.


Medical masks are recommended primarily in health care settings, but can be considered in other circumstances. Medical masks should be combined with other key infection prevention and control measures such as hand hygiene and physical distancing.

Healthcare workers - Medical masks and respirators such as N95, FFP2 or equivalent are recommended for and should be reserved for, healthcare workers while giving care to patients. Close contact with people with suspected or confirmed COVID-19 and their surrounding environment are the main routes of transmission, which means healthcare workers are the most exposed.

People who are sick and exhibiting symptoms of COVID-19 - Anyone who is sick, with mild symptoms such as muscle aches, slight cough, sore throat or fatigue, should isolate at home and use a medical mask according to WHO’s recommendation on home care of patients with suspected COVID-19. Coughing, sneezing or talking can generate droplets that cause can spread the infection. These droplets can reach the face of others nearby and land on the surrounding environment. If an infected person coughs, sneezes, or talks while wearing a medical mask, this can help to protect those nearby from infection. If a sick person needs to go to a health facility they should wear a medical mask.

Anyone taking care of a person at home who is sick with COVID-19 - Those caring for individuals who are sick with COVID-19 should wear a medical mask for protection. Again, close, frequent and prolonged contact with someone with COVID-19 puts caretakers at high risk. National decision makers may also choose to recommend medical mask use for certain individuals using a risk-based approach. This approach takes into consideration the purpose of the mask, risk of exposure and vulnerability of the wearer, the setting, the feasibility of use and the types of masks to be considered.
