With the increase in the spread of contagious Corona Virus disease, many people are sharing different points of view over the spread of this fatal disease. The Primary mode of Covid-19 transmission continues to remain large droplets even as aerosol and fomite transmission cannot be ruled out, the World Health Organization said on Thursday in its 10-page long open report given to the agency to revise its airborne transmission guidelines. After which the global health agency admitted that aerosol transmission cannot be ruled out, especially in crowded and poorly ventilated areas.

Aerosols are defined to be less than 5 micrometers or five-thousands of millimeters in size. While droplets can also be airborne, airborne transmission refers primarily to aerosol transmission in the context of Covid. It is said that the Aerosols stays in the air for several hours and spread widely, especially in unventilated indoor spaces. World Health Organization has said that Covid-19 might be transmitted at a higher speed through aerosols, which are generated from just speech or exhalation of air.


What is ‘WHO’ Saying?

In the report of the World Health Organization, it mentioned that the mode of transmission is not clear yet but these two are the main source of transmission. It added that even though the virus was detected in the air, but still the doctors are saying that it is not a viable source of transmission.

One of the WHO officials said, “The possibility of airborne transmission in public settings, especially in very specific conditions-Crowded, closed, poorly ventilated settings-cannot be ruled out. In these events, short-range aerosol transmission, particularly in specific indoor locations, such as crowded and inadequately ventilated spaces, over a prolonged period of time with infected persons cannot be ruled out”.

WHO has also stated that there is some lack of evidence for fomite transmission, stating that despite consistent evidence of the virus settling on surface, there has been no evidence of the virus spreading between individuals through this method, as those who came in contact with infected surfaces likely came in contact with infected individuals as well.

As said by the WHO, to prevent the transmission WHO recommends testing, tracing, and isolating. It said asymptomatic people can infect others, thus, they are recommended to stay away from the asymptomatic people. The agency also said that further research is urgently needed to investigate aerosol transmission understanding instances attributed to it.
