Is COVID-19 airborne? WHO releases new guidelines


  • WHO has acknowledged that there are possibilities of airborne transmission of covid-19 under certain conditions

  • The UN body releases the new guidelines on transmission including new evidence on spread of SARS-Cov-2.

The WHO on Thursday issued new guidelines on the transmission of novel coronavirus.The UN health agency have told that airborne spread of coronavirus can occur in healthcare settings particularly through droplets and aerosols.

The guidelines have stated that a clear understanding of how,when and what type of settings tend to increase transmission is required to effectively manage public health and take precautionary actions.Currently the diseases spreads via direct,indirect or close contact with infected individuals through saliva or respiratory secretions(cough,sneeze, talk or sing).Agency have also noted that this pandemic can also be asymptomatic and more research is required on its basis.

WHO have also stressed that quality research is required in order to find out the transmission in the absence of aerosol generating procedures.dose of virus required to transmit,settings and risk factors for superspread events,as well as extend of asymptomatic and presymptomatic transmission.

What is the difference between airborne transmission and droplet transmission?

Airborne means it tends to refer the microbes within the droplet nuclei,which are generally considered to be <5 micrometre in diameter.

Airborne and droplets are 2 descriptions of one phenomenon.Microorganisms less than 5 micrometers is called as airborne and more than 5 micrometers is called as droplets.airborne material can travel upto 6-9 feet and droplets settle on some surfaces.Bacteria or virus can remain viable on surfaces few minutes to hours.close contact by a person to these surfaces and persons can easily cause transmission of the disease.Getting infected and getting disease are two different things.even if bacteria or virus enters our body immune system can fight and kill it.So its not necessary that all who are infected may get the disease.

Here is all what you can do.

  • Its always best to wear a mask. while going out especially in crowded areas to keep respiratory infections away.

  • Try to keep 3 feet distance (to prevent physical contact). Wash hands frequently with soap and water for atleast 20 seconds

  • Do not touch face unnecessarily and practice respiratory etiquette.

  • Ensure proper environmental cleaning and disinfection

  • To boost immunity have proper diet (indian square meal) and practice yoga, meditation or routine exercises.

To prevent transmission WHO recommends identifying suspect cases as quickly as possible ,testing and isolating all cases in appropriate facilities.
