Airborne aerosols particles and COVID-19 transition.

With the outbreak of Coronavirus (2019) (COVID-19), as of late March 2020, understanding how the cause of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmitted is one of the most important questions that researchers are seeking to answer; because this effort helps to reduce the spread of disease. The COVID-19 is highly transmissible and deadly. Despite "tracking the call" and carefully examining patient contact, it is not yet clear how the virus is transmitted from one sick person to another. Why it is so transmissible? Can viruses be transmitted through speech and exhalation aerosols? How far can these aerosols go? How long can an aerosol containing a virus stay in the air? Is the virus amount in these aerosols enough to lead to an infection? There is no consensus on aerosols' role in the transmission of SARS-CoV-2. Findings show that SARS-CoV-2 aerosol transmission is possible. Therefore, to effectively reduce SARS-CoV-2, precautionary control strategies for aerosol transfer should be considered. Our aim is to review the evidence of the aerosol transmission containing SARS-CoV-2.
