COVID-19 transmission is airborne

A study published in the peer-reviewed medical journal The Lancet earlier this month asserted that SARS-CoV-2 (novel coronavirus) is an airborne pathogen. Researchers said detailed analyses of human interactions and other variables cannot be adequately explained by droplets or fomites as is the predominant scientific view.
  • 'Airborne' does not mean the air is contaminated, said Dr Younus referring to the Lancet study
  • The study said SARS-CoV-2 stayed infectious in the air during laboratory experiments
  • Ditch cloth masks, advised chief of Infectious Diseases at the University of Maryland, Dr Faheem Younus

Reacting to the study, Dr Faheem Younus said on Saturday that 'airborne' means the virus "may remain suspended in the air — typically in indoor settings —and pose a risk".


The recent study by six experts from the UK, the US and Canada, also stated that Covid-19 stayed infectious in the air for up to three hours in the case of laboratory experiments. It was also identified in air filters and building ducts in hospitals housing Covid-19 patients, the study went on to say.

Best mask to consider:

Before buying any mask online we would suggest you read the reviews. While wearing any mask the following things should be taken care of:

  • Wash hands before wearing a mask.
  • Follow the instructions on the package carefully, if available.
  • In general, when wearing a surgical mask, the following should be noted :
  • The colored side of the mask faces outwards, with the metallic strip uppermost;
  • The strings or elastic bands are positioned properly to keep the mask firmly
  • in place;
  • The metallic strip molds to the bridge of the nose;
  • The mask should fully cover the mouth., nose, and chin;
  • The mask should fit snugly over the face.
  • Try not to touch the mask once it is secured on your face. If you must do so, wash your hands before and after touching the mask
  • When taking off the mask, avoid touching the outside of the mask as this part may be covered with germs
  • After taking off the mask, put the mask into a plastic or paper bag before putting it into a dust bin with a lid;
  • A surgical mask should be discarded after use and under no circumstances should it be used for longer than a day. Replace the mask immediately if it is damaged or soiled.
Wearing a mask is just one of the ways to prevent respiratory tract infections. The most important thing a person should do is to observe good personal hygiene practices and a healthy lifestyle. For example, wash hands frequently with liquid soap, especially after sneezing, coughing, or cleaning the nose.
