Usage of the face mask, has been very much influential, as the aerosols released through the breath and saliva, can be easily diverted and also it causes disruption of its kinetic motion.

Amidst the crisis period imposed by the deadly corona virus a lot of researches is still ongoing regarding the settlement of a proper guideline to be safe from the corona virus. During onset of the disease, a proper medical guideline was missing, at that time. Each and every department and their scientist opted for other method of control of the disease, with a soul motto of checking the transmission rate of this deadly virus. WHO (World Health Organization) and CDC (Centre of Disease Control) came up with a lot of guidelines, that included medical as well as non-medical. One of the prominent rules that got implemented during this past one year of pandemic was “social distancing”.

Through a variety of research and studies conducted by many institutes, to understand the mechanism of transmission of the virus, from one person to another person, droplet method of transfer became very common.  Physical study of Fluids, embarked upon the fact that with normal breathing, mainly indoor condition, saliva as well as nasal gaseous outputs can travel up to 2.2 meters distance, carrying the viral particles. Moreover, with the distance, it can also reach a height of about 7 feet, within a time period of one and half seconds.

For these obvious reasons use of the mask, and a social distancing of about 6 meters have been prescribed in this pandemic condition.  A computerized simulation study has been implemented regarding this aspect. Previously the aforesaid method was used only in the case of normal cough and cold condition, like sneezing, wheezing, cough etc. However, recent studies included the breathing aspects as well.

Normal breathing also emits a lot of volatile organic compounds (VOCs), along with its saliva and nasal discharge. Usage of the face mask, has been very much influential, as the aerosols released through the breath and saliva, can be easily diverted and also it causes disruption of its kinetic motion.  Further studies will be done in respect to aerosol and its dynamics for better understanding of this transfer.
