Role of Aerosols in the Spread of Covid-19- A Review

Abstract

The COVID-19 pandemic was identified in late 2019 at Wuhan, China. Its outbreak causes respiratory illness. It is considered to be a potential zoonotic disease and is asymptomatic or flu-like.SARS is a new clinical entity of the COVID-19 outbreak. The other symptoms are fever, sore throat, cold. They spread through droplets, saliva, or sneeze. They are also transmitted to the child by placental transmission. The airborne transmission is by aerosols where droplets are >5μm. They become bioaerosols and are found to travel more than 100 meters. In experimental work, it is found that the particles of COVID can be detected 3 hours after no clinical setting. The only way to stop the spread is appropriate preventive measures like PPE, respiratory etiquette, and social distancing. There are some recent advances in the field to stop the spread of COVID-19. In this review, we discuss the transmission and spread of coronavirus by aerosols and the various preventive measures used by medical practitioners to stop the spread of this pandemic.
