ABSTRACT
Airborne transmission of COVID-19 is possible under specific circumstances in which procedures that lead to aerosol production are carried out. Persistent heaviness and pains in the chest, shortness of breath, loss of appetite, confusion, irritability, impaired consciousness, depression-associated disorders, sleep disorders, stroke, brain inflammation, delirium, and nerve damage have also been reported as the less common symptoms associated with COVID-19. Naturally, coronaviruses are benign but they might gain the ability to cause severe diseases in humans if they undergo appropriate mutations in primary and intermediate hosts. The scientific community has been studying human coronaviruses for a long time but the outcome of exposure to the novel coronavirus SARS-CoV-2 and the disease it causes is a bit different compared with SARS-CoV, MERS-CoV, and so on. Coronaviruses belong to a family of viruses that have ribonucleic acid as their genetic material and have the ability to cause diseases in birds and mammals.
